  • Development of dandelion ( spp.) quality evaluation technology based on
           phenolic acids

    • Abstract: One of the main purposes for which dandelions are cultivated is to derive phenolic acids from their processing. Phenolic acids, which are one of the main useful compounds in dandelion, constitute one of the important groups of therapeutically significant bioactive compounds in traditional Chinese medicine. To carry out a relatively full evaluation of dandelion quality, it was found advisable to use multiple indices to avoid conflict with the single evaluation index stipulated by China Pharmacopoeia. Thus, a quality evaluation method was created based on traditional Chinese medicinal theory and relevant statistics on phenolic acids. Firstly, four main kinds of phenolic acids – caftaric acid, chlorogenic acid, caffeic acid and cichoric acid – were chosen as the main indices for quality evaluation through the optimisation of high performance liquid chromatography detection conditions and fingerprint comparison analysis; then, the content of each component was divided into five levels based on the descriptive statistics of 578 dandelion samples and references; finally, the equal weight average method was used to convert content levels of the four components into a comprehensive quality index, which served as the means for dandelion quality to be identified and segregated into grades, as follows: Grade 1 (super high, probability of 0.8%), Grade 2 (high, 18.72%), Grade 3 (medium, 37.28%), Grade 4 (qualified, 32%) and Grade 5 (low, 11.2%). This method is the first to comprehensively evaluate dandelion quality for setting an industry standard in China, and has practical and scientific characteristics.

  • Waste apple wood: A safe and economical alternative substrate for the
           cultivation of and

    • Abstract: The use of waste apple-wood as a source of sawdust to cultivate the mushrooms Pleurotus ostreatus and Lentinula edodes is a common practice, but it is imperative to ensure that the wood does not contain unsafe amounts of heavy-metals or pesticide residues. In this study, we sampled and investigated the pollution of heavy metals and pesticide residues in apple-wood from Yantai, Shandong, China and cultivated P. ostreatus and L. edodes using apple-wood as substrate. Heavy metals, pesticide residues, mineral elements, and biological efficiency were measured. Heavy metals were more commonly detected in the 73 apple-wood samples, but serious pollution was only an isolated phenomenon. No Pb was detected in P. ostreatus and L. edodes. The contents of Hg, As, Cd, and Cr were at safe levels. The contents of Ni were equivalent to those of wild mushrooms. Most notably, chlorpyrifos was detected in all the apple-wood tested. However, chlorpyrifos was only detected in L. edodes cultivated with apple sawdust. No other pesticide residues were detected in the other mushroom samples. The biological efficiency of P. ostreatus cultivated by apple sawdust was 89%, which was 80% of the control. The biological efficiency of L. edodes cultivated with apple sawdust was 81%, which did not differ significantly from the control. Apple-wood can replace wild oak as the material for L. edodes cultivation, but producers should ensure that the raw materials are safe. The main materials chosen to cultivate P. ostreatus should balance the two factors of raw material price and biological efficiency.

  • Optimization of solvent-free microwave-assisted extraction of antioxidant
           compounds from fruit by response surface methodology

    • Abstract: Lagenaria siceraria (bottle gourd) fruit is highly celebrated for its nutritional as well as therapeutic properties. The present study was undertaken with the aim of exploring an efficient green solvent-free microwave-assisted extraction method for bioactives from this fruit. Optimization was done according to response surface methodology (RSM), where microwave power (W) and time (s) were independent factors, and percent extraction yield, total phenolic content (TPC), total flavonoid content (TFC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, ferric reducing antioxidant potential (FRAP) and iron chelating activity (ICA) were the responses. TPC, TFC, DPPH radical scavenging activity, FRAP and ICA were highest at 480 W and 60 s. The TPC was 288.9 mg GAE · g−1 DW (milligram gallic acid equivalent per gram dry weight), TFC was 214.1 mg RE · g−1 (rutin equivalent per gram DW), anti-radical activity was 32.96%, FRAP was 289.7 mg AAE · g−1 (mg ascorbic acid equivalents per gram) and ICA was 19.52%. The results of the study thus demonstrate that the solvent-free microwave-assisted extraction method, which utilised an optimum power of 480 W and a time of 60 s, is an effective and green method for extraction of antioxidant compounds from bottle gourd fruit.

  • First characterisation of chrysanthemum virus B infecting chrysanthemum in
           Thailand and development of colourimetric RT-LAMP for rapid and sensitive
           detection

    • Abstract: Chrysanthemum is among the world's most important ornamental plants because of its high economic and cultural value. Our report is the first to describe the detection of chrysanthemum virus B (CVB) in chrysanthemum leaf samples collected from Thailand, which showed yellowing and mild mottling symptoms. The coat protein sequences of CVB isolated in this study share 95.15% identity with previously characterised CVB isolates. Biological indexing found that CVB induced both local and systemic symptoms in tobacco plants, while petunia displayed systemic symptoms. To improve the rapidity and sensitivity of CVB detection, the loop-mediated isothermal amplification (LAMP) technique was developed. LAMP detection was found to be optimal when incubation was conducted at 65 °C for 45 min, wherein the LAMP reaction demonstrated 106 times higher sensitivity than polymerase chain reaction. To simplify the interpretation of results, we designed the method such that a positive result is clearly indicated based on a change of colour (colourimetry), from pink to yellow, as observed visually and via gel electrophoresis. To our best knowledge, this is the first report on the characterisation of molecular, biological and morphological characteristics of CVB infecting chrysanthemum in Thailand, along with the development of colourimetric RT-LAMP for improving detection efficiency.

  • Foliar application of potassium silicate, potassium fulvate and betaine
           improve summer-time tomato yield by promoting plant nitrogen and potassium
           uptake

    • Abstract: During the summer months, greenhouse tomato production is challenged by the heat, causing yield reduction; therefore, we conducted a study to test the effectiveness of different foliar spray compositions for the improvement of Lycopersicon esculentum var. cerasiforme ‘Qianxi’ nutrition uptake and fruit yield. Two forms of silicon, two kinds of organic nitrogenous compounds and water as the control factor were two-two paired to become nine different recipes, which were as follows: CK (H2O), ISi (K2SiO3), organic silicon (OSi), potassium fulvate (BSFA), BSFA + ISi, BSFA + OSi, betaine (GB), GB + ISi and GB + OSi. The plants were sprayed three times during the period of the first, second and third truss fruit expansions with a 2-week interval. As a result, BSFA or K2SiO3 generated higher yield in plants compared with the other compositions. Also, K2SiO3 significantly enhanced the total nitrogen, phosphorus and potassium accumulation in fruit and the whole plant. Comparing across the nine recipes, BSFA + ISi, ISi and GB had improved the fruit yield by 17%, 12.7% and 9.5%, performing the best. BSFA + ISi, ISi and GB also improved the plant nitrogen uptake by 8.2%, 18.8% and 9.8%, as well as the potassium uptake by 16.2%, 12.3% and 15.2%, compared with CK, respectively. Thus, K2SiO3, BSFA and GB stimulated the plant nitrogen and potassium uptake, which improved the marketable yield.

  • Mathematical modelling of Hass avocado firmness by using destructive and
           non-destructive devices at different maturity stages and under two storage
           conditions

    • Abstract: Devices which are used to determine firmness of non-destructive nature do not penetrate the skin or damage the underlying flesh of the fruit and do provide real-time results, avoid raw biomass loss and allow the testing of every individual fruit and repeated testing of the same fruit, thus providing many advantages for researchers and the industry alike. Contrarily, destructive methods puncture the fruit and thus only a subsample, selected to represent all fruit, can be tested. In addition, different operators can generate quite different values for the same fruit using a hand-held penetrometer. Hass avocado from two commercial orchards was collected, and fruit firmness was measured at harvest, during two storage conditions controlled atmosphere (CA) and regular air (RA), during shelf-life and at the ready-to-eat stage using both destructive (Fruit Pressure Tester, mod. FT327, Wagner Instruments, Greenwich, USA) and non-destructive devices (Model TA.XT plusC, Stable Micro Systems Ltd, England). Then, the mathematical relationship between these two devices was assessed using Spearman Correlation coefficient (rho) and p-values adjusted by Benjamini-Hochberg and Bonferroni procedures. Thus, 3,200 fruits were evaluated during two harvests and two subsequent seasons. A moderate and positive association between destructive and non-destructive devices was found (rho coefficient ranging from 0.41 to 0.51). The variance explained by the regression models ranged from 0.53 to 0.63; all of them were significant with good accuracies (i.e., 0.79; 0.78; 0.73; 0.76). The results prompt us to conclude that a non-destructive texture analyser device can be used to accurately predict firmness measured by a penetrometer in Hass avocado fruit and contribute to avoiding fruit discards.

  • Zn induces changes in activities of mitochondrial respiratory chain
           complexes and emissions of floral volatiles in

    • Abstract: In recent years, there has been increasing interest in floral volatiles due to their important function in reproduction, self-protection and so on. Although some progress was made on deciphering emissions of floral volatiles and on related mechanisms under a variety of environmental factors, the effects of Zn2+ concentrations on mitochondrial function and floral volatile emissions are yet to be revealed. Dendrobium huoshanense petals were used as materials and were treated with a 0–8 mM ZnSO4 solution. Intracellular Zn2+ concentrations were evaluated by the fluorescent dye method and atomic absorption method. Mitochondrial respiratory chain complex activities and the precursor and ATP contents were determined by the biochemical method. Floral volatile components were analyzed by the gas chromatograph-mass spectrometer (GC-MS). The results indicated that ZnSO4 application significantly increased intracellular Zn2+ concentrations. Elevated intracellular Zn2+ concentrations differently affected mitochondrial respiratory chain complex activities, precursor and adenosine triphosphate (ATP) productions and floral volatile emissions. Moreover, positive correlations exist among the activities of mitochondrial respiratory chain complexes, productions of precursors and ATP and emissions of floral volatiles. It is concluded that Zn2+ concentrations induce the activity changes of mitochondrial respiratory chain complexes, especially complex II and V, which promote or inhibit the emissions of floral volatiles by affecting the precursor and ATP levels that are closely related to the production of terpenoids, benzoids and fatty acid derivatives. The research will contribute to understanding the relationship between Zn2+ concentrations and floral volatile emissions from the perspective of mitochondrial function.

  • Perceived functions of allotment gardens and their importance during the
           COVID-19 pandemic in Poland

    • Abstract: This article describes the changes taking place in the functions of allotment gardens, their perceived value, reasons for purchasing allotments and subjective (self-reported) assessments of their importance during the pandemic. A questionnaire survey was conducted among 203 owners of allotment gardens located in three highly urbanised cities in the Silesian Voivodeship (Southern Poland). Semi-structured questionnaires and non-standardised questionnaires were used to collect the data. The results demonstrate that the respondents aged above 61 years (38.5%) have observed a generational change in the function of allotments, from cultivating fruits and vegetables to recreational purposes. Regardless of age, the owners of allotment gardens did not notice any technological progress or new crops. The young respondents (21–30 years) treated allotment gardens as an investment (36.7%), while the respondents aged below 20 years and over 61 years declared that the greatest benefits of allotment gardening are improved health and growing one’s own fruits and vegetables. The respondents aged over 41 years (25.9%) also pointed out the importance of growing their own produce. Allotments were especially important during the pandemic as a private space free from COVID-related restrictions. Extended interviews with the respondents revealed that allotment gardening was perceived as a coping strategy for the stress generated during the lockdown. This study showed that allotment gardens are important sites not only for food production but also for maintaining mental health, social capital and environmental engagement.

  • Therapeutic horticulture as a potential tool of preventive geriatric
           medicine improving health, well-being and life quality – A systematic
           review

    • Abstract: The global population of older people grows systematically and with age, the physical and cognitive abilities of people decline. The amount of evidence that gardening may provide substantial health benefits and enhance the quality of ageing is increasing. This paper presents a systematic review of the therapeutic effects of horticulture and gardening on clients aged ≥60 years. It encompasses articles published in English between January 1, 2010, and December 31, 2021. The literature survey shows that the interest in the topic has grown significantly in recent years as over half of the published studies are from 2019 to 2021. Most of this work was done in Asia (60%), America, Europe, Australia and New Zealand. The most commonly used interventions were active horticultural therapy programs or gardening, but 20% of the studies explored the passive connection of being outside. The fitness of the elderly was measured using 33 psychological tests, 32 physiological and functional parameters and different kinds of self-developed questionnaires and interviews. The most commonly used psychological tests were the Geriatric Depression Scale, Self-rated Health and Quality of Life, Mini-Mental State Examination, Friendship Scale, Lubben Social Network Scale, and the Attitudes to Ageing Questionnaire. The physiological and functional parameters included heart rate variability, blood pressure, electroencephalography, brain nerve growth factors, and different types of biomarkers. The study outcomes demonstrated positive results of horticultural therapy on human health and well-being, particularly in a psychological dimension and to a smaller but still significant extent physiological aspect.

  • Comparative RNA-Seq analysis to understand anthocyanin biosynthesis and
           regulations in

    • Abstract: Anthocyanins play a critical role in flower colour pattern formation, and their biosynthesis is typically regulated by transcription factors (TFs). Curcuma alismatifolia is a well-known ornamental plant with colourful flowers. However, little is known about the genes that regulate anthocyanin accumulation in C. alismatifolia. In the present study, high-quality RNA was extracted from three flowering stages of ‘Dutch Red’ and the blossoming stage of ‘Chocolate’. In all, 576.45 Mb clean data and 159,687 de-redundant sequences were captured. The Kyoto Encyclopedia of Genes and Genomes analysis showed that the pathways of phenylpropanoid biosynthesis, flavonoid biosynthesis, flavone and flavonol biosynthesis, and terpenoid backbone biosynthesis were the most enriched. Thirty unique isoforms were annotated as encoding enzymes or TFs involved in anthocyanin biosynthesis. Further analysis showed that the up-regulation of anthocyanin biosynthesis genes was associated with the red colour formation of ‘Dutch Red’, and their expression was induced at the initial flowering stage. The gene flavonoid 3′, 5′-hydroxylase, a key enzyme in the formation of delphinidin-based anthocyanins, reduced expression in ‘Chocolate’. In addition, we identified totally 14 TFs including 11 MYB proteins and 3 WD proteins, which might play important roles in the regulation of anthocyanin biosynthesis. The quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) results were generally consistent with the high-throughput sequencing results. Together, the results of our study provide a valuable resource for the regulatory mechanism of anthocyanin biosynthesis in C. alismatifolia and for the breeding of Curcuma cultivars with novel and charming flower colours.

  • Screening of composite substrates suitable for tissue-cultured plantlets
           growth of (Lour.) Merr

    • Abstract: Asparagus cochinchinensis (Lour.) Merr is a medicinal, edible and horticulture plant. Seedling breeding relies on tissue-cultured technology, but the transplant from tissue-cultured seedlings to field cultivation poses a problem in the large-scale production of A. cochinchinensis. Tissue-cultured seedlings of A. cochinchinensis were used as materials, and they were transplanted into the substrates that were mixed with coconut bran, peat, vermiculite, perlite or garden soil. The analysis of the physical and chemical properties of the substrate, combined with the survival rate of seedlings, the aboveground parameters (plant height, stem diameter, fresh weight and dry weight), underground parameters (root fresh weight, root dry weight, root length, root diameter, root surface area and root volume) and physiological indexes (malondialdehyde, soluble protein, soluble sugar, proline, chlorophyll and root vigour), allow us to understand the effects of different combination substrates on the growth and physiology of A. cochinchinensis tissue-cultured seedlings. We concluded that the survival rate of seedlings was negatively correlated with the bulk density and conductivity and was positively correlated with the porosity in the substrate. The membership function was used to comprehensively evaluate the indexes of each combination substrate, and it was concluded that coconut bran:perlite:vermiculite = 33.33%:33.33%:33.33% (bulk density = 0.23 g · cm−3, total porosity = 65.07%, pH = 6.30, conductivity = 0.51 mS · cm−1) scored the highest, the survival rate of seedlings reached 87.10%, the aboveground and underground growth were vigorous and the quality was better than other substrates. This research provides technical support for the efficient cultivation of tissue-cultured seedlings of A. cochinchinensis and reduces the cost of raising seedlings.

  • Differences in health-promoting properties in civilisation diseases of
           fruiting bodies harvested from three flushes

    • Abstract: A controlled environment and composition of the compost used for the commercial production of Agaricus bisporus can allow fruiting bodies with increased nutritional value to be obtained. The present study aimed first to investigate the content of bioelements in fruiting bodies of A. bisporus harvested from three flushes of cultivation and to estimate which elements are accumulated most effectively by determination of bioconcentration factor (BCF). The second aim of the study is to determine the amount of selected organic compounds in the A. bisporus fruiting bodies harvested from three flushes of cultivation and to evaluate their antioxidant activity. Among the three examined A. bisporus flushes, the first is considered the most valuable, since it was rich in dietary and nutritional substances, and has shown promise of antioxidant and antidepressant activities. The present study is the first to describe a complex evaluation of the content of bioactive substances and antioxidant activity in three different cultivation flushes of A. bisporus fruiting bodies.

  • Agronomic traits, secondary metabolites and element concentrations of
           leaves as a response to single or reiterated drought stress: How effective
           is the previously experienced stress'

    • Abstract: In nature, plants are constantly challenged by an array of drought episodes, which critically affect the distribution of the plants. The drought episodes might occur recurrently, so the plants endure drought by adjusting and shifting their metabolisms. The impacts of subjecting plants to drought stress have been widely investigated, but reports on how reiterated drought stress affects the plants are limited. The present study was designed to investigate the response of lavender, a reputed medicinal and aromatic plant, against single drought, recovery and reiterated drought stress at greenhouse conditions. In this regard, the experimental design was based on three cycles of 11 days of drought by withholding water, followed by subsequent periods of 6 days of recovery, and then double-stressed and single-stressed periods. As expected, the present findings revealed that single stress decreased the fresh and dry weights of the leaf, stem and root. Reiterated drought stress caused critical reductions in the fresh weight of the leaf, stem and root, while the dry weight of stem and root were not significantly affected. Of the estimated traits, only the dry weight of leaf increased with reiterated drought stress. The mineral status of the leaves was adversely affected with single stress, but the effects of recovery and reiterated stress were not in accordance with the improvement in water contents of the leaf and soil. Regarding essential oil compounds, eucalyptol, camphor and endo-borneol were predominant. Single and reiterated drought stress increased camphor percentage, while recovery and full irrigation decreased the percentage. Endo-borneol was decreased under single stress, but reiterated stress increased the percentage of the compound. Considering the phenolic acids, stressed and non-stressed groups were well discriminated and hence, phenolic acids might be useful as good indicators of the stress response in lavender.

  • Outcomes of foliar iodine application on growth, minerals and antioxidants
           in tomato plants under salt stress

    • Abstract: Plant biostimulants have been used to reduce the damage caused by different types of biotic and abiotic stresses. Iodine (I) is a non-essential element in plants. Still, it is considered beneficial and a biostimulant, since exogenous application can enhance the redox metabolism, which improves antioxidants, synergies with essential minerals and increases tolerance to adverse factors. However, little is known about the mechanism of action of iodine; so, it is advantageous to undertake research that elucidates the impact of this element on plant physiology, which is expected to encourage the productive agricultural sector to use this element with additional biofortification benefit. The objective of this research was to evaluate the effect of foliar KIO3 applications every 15 days at 100 μM, on growth, mineral content and antioxidants in tomato plants grown under greenhouse conditions subjected to salinity stress (100 mM NaCl). The results showed that iodine did not mitigate the adverse impact of salinity on fresh or dry biomass but increased fruit production by 23%. A greater amount of N and Fe was also found in the leaves but not in the fruits; the same happened with the iodine concentration, which was high in the leaves of the treated plants but not in tomato fruits. The content of Ca and Mg in fruits was decreased in plants treated with iodine, as well as the activity of the GPX, lycopene and the antioxidant potential. None of the fruit quality variables were affected by salinity with or without application of iodine.

  • Yield parameters, antioxidant activity, polyphenol and total soluble
           solids content of beetroot cultivars with different flesh colours

    • Abstract: This study aimed to evaluate yield parameters, antioxidant activity (AOA), total polyphenol content (TPC) and total soluble solids (TSS) in beetroot cultivars with different flesh colours. Field experiments were established at the Slovak University of Agriculture in Nitra in 2016 and 2017. Within the study, 16 beetroot cultivars were tested, including 11 red-fleshed (‘Boltardy’, ‘Boro’ F1, ‘Crosby Egyptian’, ‘Cylindra’, ‘Detroit Globe’, ‘Detroit 2’, ‘Egyptian Turnip Rooted’, ‘Opolski’, ‘Pablo’ F1, ‘Renova’ and ‘Taunus’ F1), 2 yellow-fleshed (‘Boldor’ F1 and ‘Golden’), 2 white-flesh cultivars (‘Albino’ and ‘White Detroit’) and 1 red-white fleshed cultivar (‘Chioggia’). All beetroot cultivars with red flesh colour showed higher AOA and TPC than different-coloured beetroot cultivars. The highest root yield was found in the white-fleshed beetroot cultivar ‘Albino’ (37.80–41.91 t · ha−1). The highest root weight was found in the white-fleshed beetroot cultivar ‘White Detroit’ (362.4–412.1 g). The highest AOA (819.19–972.50 mg TEAC · kg−1 d.w.) and TPC (2,387.70–2,731.00 mg · kg−1 d.w.) were found in the red-fleshed beetroot cultivar ‘Pablo’ F1. Different-coloured cultivars of beetroot were characterised by a lower content of TSS (6.4–8.8 ºBRIX) than cultivars with typical, red flesh colour (7.8–10.8 ºBRIX). Results clearly indicate that cultivar, or flesh colour, is showed as a significant factor influencing the quality of beetroot. Knowing of yield potential and quality of beetroot cultivars is important for growers as well as consumers. Results of this study indicate that white-fleshed cultivars of beetroot are characterised by high yield potential but lower quality, including lower AOA, TPC and TSS.

  • Nitrogen supply and shading affect morphology and composition of the
           essential oil in marigold ( L.)

    • Abstract: Terrestrial plants are constantly exposed to multiple environmental signals that influence their metabolism. Among these signals, nitrogen (N) nutrition and light affect importantly diverse metabolic and physiological processes. Herewith the effects of N nutrition (8.47, 12.71 and 16.94 mg · L−1 N) and shading percentages (0 and 70%) on plant morphology and chemical composition of the essential oil of marigold (Tagetes erecta L.) ‘Inca’ were assessed. Increasing N levels enhanced the number of secondary branches and the flower diameter, while shading reduced height of side branches, number of primary branches and opened flower buds. In leaves, flowers and stems, 15 different compounds were identified. In leaves, low and medium N levels and high light level increased the synthesis of ocimene, limonene and piperitone. As well, medium and high N doses, independently of the light level, stimulated the synthesis of caryophyllene and β-phellandrene in leaves. Nevertheless, increasing N doses and shading level decreased the synthesis of β-myrcene and α-pinene in leaves. In flowers, medium N level and high light intensity increased the synthesis of trans-pinene. Piperitone and verbenone were identified only in flowers of plants with high N doses and lower light intensity. In the stems, caryophyllene, piperitone and β-farnesene were more abundant with medium and high N levels. The interaction of study factors differentially affected both morphological variables and the composition of essential oil among organs studied. Therefore, N nutrition and light intensity are key factors that modify the morphology and composition of the essential oil in T. erecta.

  • Functional traits of okra cultivars (Chinese green and Chinese red) under
           salt stress

    • Abstract: Two okra cultivars (Chinese green and Chinese red) were subjected to salt stress for 12 weeks. Salt stress treatments T1 (20.8 mM), T2 (103.3 mM), T3 (180.0 mM) and T4 (257.0 mM) were applied with equal proportions of NaCl and CaCl2 in Hoagland nutrient solution. Salt stress significantly affects photosynthesis, transpiration, stomatal conductance, water use efficiency, water potential, plant height, root length, fresh weight and dry weight of both okra cultivars in every salt stress treatment. At T2, T3 and T4, Chinese red plants maintained their physiological and growth traits up to Weeks 9, 6 and 3, respectively; beyond these salt-stress durations, growth reductions were found. Similarly, Chinese green plants maintained their growth up to Weeks 9, 5 and 3, respectively, at T2, T3 and T4 treatments. In comparison, Chinese red showed more tolerance than Chinese green. According to the results, the third and ninth weeks are the tolerance threshold limits for both cultivars to sustain their physiological traits and growth under T4 and T2 salinity treatments. Similarly, Chinese red has the threshold limit to bear T3 treatment up to the eighth week and Chinese green, up to the fifth week. Thus, this study provides a new method to determine the threshold value of crops with respect to duration under salt stress. This finding would be useful in the field of water saving and utilisation of saline water resources.

  • Evaluation of yield and nitrogen utilisation with urease and nitrification
           inhibitors in sweet potato crop ( L.)

    • Abstract: Sweet potato (Ipomoea batatas L.) is a new tuber crop grown in Greece. It constitutes an innovative dietary component for both humans and animals, due to its nutritional properties. The cultivation of sweet potato focuses on the growth of both tubers and plants. Nitrogen is considered an essential element for almost all crops. This study set out to compare the effect of nitrogen inhibitors on yield components of sweet potato. In the literature, it is stated that in sweet potato cultivation nitrogen mainly affects the plants’ growth such as the tuber's yield and some quality characteristics such as dry matter and protein content. To furthermore explore this particular area, field experiments took place in West Greece, during the years 2018 and 2019. Several urea combination treatments were used in the experimental process. The treatments were urea (46-0-0), urea with urease inhibitor (UI), urea with nitrification inhibitor (NI), urea with double inhibitors (UI + NI) and control (without fertilizer) in a randomised complete block design. Leaf area index (LAI) was significantly affected by the fertilizer marking the highest value of 5.35 under urea + UI + NI treatment. Marketable yield was profoundly affected by the fertilizer in the experimental years and ranged from 18,180 to 23,230 Kg · ha−1 whereas non-marketable yield was not affected by the fertilizer. A considerable impact of fertilizers was noticed on yield where the highest value was 30,923 Kg · ha−1 under urea + NI + UI treatment. The percentage of nitrogen on tubers and upper parts was significantly affected by the fertilizers. Nitrogen markers, such as nitrogen use efficiency (NUE), nitrogen harvest index and nitrogen agronomic efficiency (NAE), were used to evaluate nitrogen release. A significant positive correlation was noticed between marketable yield and NUE (0.774). Also, the significant increase in yield showed a positive correlation with NAE (0.727). For yield components of sweet potato, the highest values were observed in urea with double inhibitors treatment in both experimental years.

  • Effects of constantly high soil water content on vegetative growth and
           

    • Abstract: Excess water in vineyard soils during grapevine growing season is expected to become a critical issue in Japan. The objective of this study was to investigate the effects of constantly high soil water content which was controlled at constantly more than 20% water content in soil on vegetative growth and berry quality of Cabernet Sauvignon over a 3-year growing season. A wireless sensor networking system for real-time monitoring of soil moisture was used to check that the experimental plot had constantly more than 20% water content in soil. Véraison in the experimental plot controlled at constantly high soil water content started 10 days, 4 days and 1 day later than that in the non-irrigated experimental plot in the 2017, 2018 and 2019 growing seasons, respectively. The constantly high soil water content had no notable effects on berry quality, such as berry characteristics and berry composition, at harvest compared with the non-irrigated experimental plot, although there was a certain tendency that constantly high soil water content decreased anthocyanin contents in berry skins compared with those of non-irrigated grapevines during the three growing seasons. We postulated that waterlogging damage due to the increase in soil water content by frequent rainfall would be minimised by the selection of rootstock that confers tolerance to waterlogging stress for scion cultivars and/or viticultural practices to prevent decrease in soil temperature. Also, the introduction of Internet of Things technology for monitoring water status in vineyard soil is expected to contribute to improving practical approaches to vineyard soil water management.

  • Comparison of physico-chemical characteristics of myrtle at different
           ripening stages

    • Abstract: The fruits of myrtle at different stages of development, namely green (G), colour break (C) and mature (M), were used to investigate the changes of fruit quality and anthocyanin composition during its development. Five anthocyanin components, such as delphinidin (Dp), cyanidin (Cy), pelargonidin (Pg), peonidin (Pn) and malvidin (Mv), were detected. Among them, the content of Dp glucoside was the highest (2.12 μg · g−1) and the content of Pn glucoside was the lowest (0.17 μg · g−1) at the green stage. The content of Cy glucoside was the highest (120.94 and 1,200.03 μg · g−1), and the content of Mv glucoside was the lowest (19.50 and 62.72 μg · g−1) at the colour break and mature stages. The single fruit weight, vertical diameter and transverse diameter at the mature stage were significantly higher than those at the colour break and the green stages by 0.87 g, 1.27 mm, 1.53 mm and 1.54 g, 3.4 mm, 3.55 mm, respectively. Fruit quality, the contents of soluble sugar and carotenoids, gradually increased with the development of fruit; and the contents were the highest at the mature stage (17.68% and 16.90 μg · L−1). The contents of titratable acidity, total phenol, flavonoids, chlorophyll a and total chlorophyll gradually decreased with the development of fruit, the content was the lowest at the mature stage (2.71 mmol · 100 g−1, 9.29 μg · g−1, 0.1%, 0.37 μg · L−1, 0.9 μg · L−1) and the content was the highest at the green stage (5.25 mmol · 100 g−1, 21.07 μg · g−1, 0.17%, 8.86 μg · L−1, 15.47 μg · L−1). The difference between the green period and the colour break period was significant.
