  • Einfluss von Biostimulanzien und Lichtreflexionsfolie auf die
           Fruchtqualität und Farbentwicklung bei Apfel
    • Authors: Henrike Schuhknecht; Lutz Damerow; Achim Kunz; Michael Blanke
      Pages: 89 - 103
      Abstract: Zusammenfassung Ziel der Untersuchungen war es, den Einfluss von Licht reflektierenden Gewebefolien und Biostimulanzien auf die Fruchtausfärbung bei Apfel zu untersuchen. Die vierjährigen Apfelbäume der Sorte ‘Braeburn, Hillwell‘ auf M9 und 1 m × 3 m Pflanzabstand standen auf dem Campus Klein-Altendorf. Zwei Licht reflektierende Mulchfolien wurden im Herbst 2015 sieben Wochen vor der Ernte beidseits der Baumreihen ausgelegt, sowie zwei Biostimulanzien jeweils vier und zwei Wochen vor der Ernte appliziert; als Kontrolle dienten angrenzende unbehandelte Apfelbäume mit Grasstreifen. In 2015, einem Jahr mit guter Fruchtausfärbung, verbesserten die beiden Reflektoren die Rotfärbung der Äpfel signifikant von 71°hue der Kontrollfrüchte (Grasstreifen) auf 49°hue (Lumilys®-Folie) und auf 40°hue (Extenday®-Folie). Die Färbung der Unterseite der Frucht wurde von 85°hue der Kontrolle auf 52°hue durch Lumilys® bzw. 40°hue durch Extenday® verbessert, entsprechend 69 % Früchte in der Farbklasse mit 75–100 % roten Deckfarbanteil mit Extenday® gegenüber 44 % mit Lumilys® und den Kontrollparzellen mit 16–26 %. Zuckergehalt (°Brix) und Festigkeit (kg/cm2) blieben durch die reflektierenden Mulchfolien unverändert; Apfelfrüchte mit Reflektoren bauten die Stärke langsamer ab, ihr Streif-Index war signifikant höher und sie reiften etwas langsamer. Der Folieneinsatz wird erst ab zweimaligem Auslegen im Jahr wirtschaftlich, wenn man nur die Materialkosten und Lebensdauer der Mulchfolien – ohne Arbeitskosten – berücksichtigt. Die Biostimulanzien brachten keine signifikanten Verbesserungen weder bei der inneren noch der äußeren Fruchtqualität und der Fruchtausfärbung. Die Anteile in der Farbklasse 75–100 % rote Deckfarbe der mit Wuxal®ATRiun und Sunred® behandelten Früchte unterschieden sich nicht signifikant von den Früchten der unbehandelten Kontrollparzellen. Auch der Vergleich der Festigkeitswerte, des Zuckergehaltes und des Stärkeabbaus wies keine Signifikanzen auf, so dass – ungeachtet der Kosten für das Ausbringen der Mittel – keine Wirtschaftlichkeit bestand. Ein Vergleich der DA-Indices mit den Streif-Indices aus den Reife-Parametern Festigkeit, Zuckergehalt und Stärkeabbau ergab nicht immer eine positive Korrelation dieser Werte.

  • Interaction of Maximum Daily Trunk Shrinkage and Fruit Quality in European
           Plum
    • Authors: Yousef Rezaei Kalaj; Martin Geyer; Werner B. Herppich; Manuela Zude-Sasse
      Pages: 105 - 112
      Abstract: Maximum daily trunk shrinkage (MDS) has been suggested as an appropriate indicator of plant water status because it is closely related to stem water potential. Interaction of MDS and fruit quality was studied in plum (Prunus domestica L. ‘Jojo’/Wavit and ‘Tophit plus’/Wavit) in temperate climate. According to the MDS data, trees were grouped as low MDS (LMDS) and high MDS (HMDS). Fruit quality was analysed during fruit development (95, 103, 117 DAFB for ‘Jojo’ and 99, 112, 121 DAFB for ‘Tophit plus’) before commercial harvest. Fruit picked at commercial harvest (137 DAFB and 140 DAFB for ‘Jojo’ and ‘Tophit plus’, respectively) were stored at 2 ± 0.5 °C (90 ± 2% RH) for 28 days, and 2 days shelf life at 20 °C providing 6 measuring dates postharvest. Results confirmed that MDS was positively correlated with water vapour pressure deficit also in the apparent temperate, semi-humid climate. Transpiration of fruit from high crop load and resulting HMDS trees, which can be assessed as physiologically drought, was low compared to that of fruit from LMDS trees. Furthermore, HMDS tree grown plums had enhanced soluble solids and dry matter contents with a tendency of reduced fruit size.

  • Usage of Shoot Analyses to Assess Early-Season Nutritional Status of Apple
           Trees
    • Authors: Kadir Uçgun; Mesut Altındal; Murat Cansu
      Pages: 113 - 117
      Abstract: Mid-summer leaf analyses are commonly used as the standard method worldwide to assess the nutritional status of fruit trees. However, the analyses performed at this period yield information only about current nutritional status of the trees. Several physiological processes influencing yield and quality take place early in spring. It was reported in previous studies that dormant-season shoot analyses for some nutrients may reliably be used to assess early-season nutritional status of peach trees. The present study was conducted with the shoot samples taken in dormant-season of 150 apple orchards from Isparta region during the years 2010 and 2011. Shoot samples were taken 15 days before full bloom stage and samples were subjected to nutrient analyses. Reference values for each nutrient were indicated as 25 and 75% of the resultant values. The shoot reference values for N, P, K, Ca, Mg, Fe, Mn, Zn and B were respectively observed as 0.66–0.82%, 0.12–0.15%, 0.37–0.45%, 0.84–1.24%, 0.11–0.16%, 24.55–32.24 ppm, 11.12–17.55 ppm, 12.96–21.90 ppm and 13.33–16.00 ppm. To check the reliability of shoot analyses, leaf samples were taken from the same orchards in 7 different periods until mid-vegetation season and correlations between nutrient contents of shoots and nutrient contents of leaves taken in all periods were investigated. Significant correlations were observed between N, P, K, Mg, Mn and B contents of shoots and leaves. Therefore, it was concluded that early-season shoot N, P, K, Mg, Mn and B analyses could reliably be used to assess nutritional status of apple trees.

  • Effect of Different Storage Temperatures on Storage Life, Physico-chemical
           and Sensory Attributes of Goji Berry ( Lycium barbarum  L.) Fruits
    • Authors: Mushtaque Ahmed Jatoi; Mladen Fruk; Josip Buhin; Marko Vinceković; Marko Vuković; Tomislav Jemrić
      Pages: 119 - 126
      Abstract: Goji berries are considered as the latest super food or fruit due to its excellent nutritive and medicinal properties and usually consumed and marketed as a dried or as a juice due to its short storage life and lack of information about its postharvest behavior. The current study was an attempt to prolong its storage life simply by using different storage temperatures (−2, 0, 10 and 20 °C) and evaluating the post-storage biochemical and fruit quality. The fruits stored at 0 °C and −2 °C appeared with lowest weight losses (13.08 and 14.95%) and significantly different from fruit stored at 10 °C (18.29%) for 12 days of storage. Whereas, the fruits stored at 20 °C deteriorated within a day due to fungal decay. However, some storage disorders like cracking, peel disorder, shriveling were observed in the fruits stored under −2 and 10 °C. There were significant differences in the phytochemical attributes like SSC, TA, SSC/TA ratio, total polyphenols, DPPH, ABTS and β‑carotene while the amount of anthocyanins and CIE color variables were found non-significant. In addition, the fruits stored under 0 °C appeared fresh and healthy and hence received highest scores during sensory analysis and strongly recommended for storage of this important horticultural commodity.

  • Changes in Morphological, Physiological Traits and Enzyme Activity of
           Grafted and Ungrafted Grapevine Rootstocks Under Drought Stress
    • Authors: Seda Sucu; Adem Yağcı; Kubilay Yıldırım
      Pages: 127 - 136
      Abstract: American grapevine rootstocks are used as the most efficient control method for phylloxera disease. Vitis vinifera species are grown over these rootstocks. The rootstocks may have different drought tolerances. In present study, morphological and physiological responds and enzyme activities of grafted and ungrafted grapevines were investigated under drought stress. The rootstocks Rupestris du Lot, 420A, 5BB, SO4, 8B, 110R, 1103P, 140Ruggeri and Ramsey and K‑7 clone of Sultani Seedless grape cultivar were used as the plant material of this study. Drought stress was exerted as water deficits and stress treatments were terminated when the available moisture level dropped to 5%. Current findings revealed that grafted plants were less influenced morphologically from the droughts than the ungrafted ones. In control group, average leaf water potential was measured as −0.51 MPa for ungrafted plants and −0.46 MPa for grafted plants. In stress group, leaf water potential was measured as −2.03 MPa for ungrafted plants and as −1.69 MPa for grafted ones. Superoxide dismutase (SOD) and ascorbate peroxidase (APX) enzyme activities of both grafted and ungrafted plants increased with drought stress. Considering the enzyme activities of ungrafted plants in control and stress groups, it was observed that SOD activity increased from 508 (unit/mg protein) to 852 (unit/mg protein); APX activity increased from 153 (micromole/mg protein/min) to 584 (micromole/mg protein/min). In grafted plants, SOD activity increased from 639 (unit/mg protein) to 796 (unit/mg protein); APX activity increased from 414 (micromole/mg protein/min) to 1002 (micromole/mg protein/min). The drought resistant rootstocks (like 140Ru, 110R) exhibited higher enzyme activity in both control and stress groups than drought sensitive rootstocks (like 5BB, SO4).

  • Genetic Diversity Among Juglans Regia Genotypes Based on Morphological
           Characters of Nut
    • Authors: Sina Cosmulescu; Dragos Stefanescu; Mariana Birsanu Ionescu
      Pages: 137 - 143
      Abstract: Walnut germplasm from three different sites in Oltenia region, located in the southwestern part of Romania, was evaluated to determine the variability and to identify promising types. A total of 64 genotypes were evaluated using morphological characteristics of nuts. Considerable genetic variation in the measured traits was found in native trees which were of seedling origin. Variability found was between 7.62–20.90 g in nut weight, between 31.17 and 53.60 mm in nut length, between 24.81 and 37.48 mm in nut diameter I, and between 23.64 and 36.18 mm in nut diameter II. Separation of the three areas in multivariate space was assessed by calculating the Mahalanobis distance. The highest inter-populations value was observed between Bechet and Ostroveni population (1.83), followed by Sadova and Ostroveni population (1.08), which indicates a wide genetic distance between these populations. Cluster analyses showed a considerable diversity within the same germplasm population. The results indicated that most of genotypes were suitable in terms of morphological traits of nut. These data demonstrated large phenotypic diversity of nut among the selected genotypes that can be considered as a valuable gene stock for breeding programs.

  • A Study on the Effect of Nitrogen Spray at Different Times on Color and
           Yield Parameters of Grape cv. Pykany
    • Authors: Mina Razmi; Bahram Abedy; Ali Tehranifar
      Pages: 145 - 152
      Abstract: In order to study the effect of nitrogen spray at different times on color and yield parameters of grape cv. Pykany, an experiment was carried out in factorial based on randomized complete block design with four replications in Khalil Abad County in 2015. The treatments included three concentrations of nitrogen (0, 5 and 10 ppm) and three spray times (Late April, before bloom stage, and after pollination and fruit set stage). Color parameters such as brightness rate (L), redness (a) and yellowness (b), chroma, hue angle and browning index were evaluated in this experiment. The results of variance analysis and means comparison showed that the effect of treatment containing spray at concentration of 10 ppm on yield was significant at 1%. There were not significant differences among treatments of urea concentrations and spray times on L and b but different concentrations of urea had significant effect on a* at the level of 1%, so that the highest amount of significant difference was due to the treatment of urea spray at the concentration of 10 ppm and the lowest amount was due to the control treatment. Furthermore, the interaction effect of concentration and different times of nitrogen application on color intensity index was significant at the level of 5%. Based on the results, the effect of different concentrations of urea spray on hue angle was significant at 1% so that the highest level of significant difference was due to the concentration of 10 ppm and the lowest was related to control treatment.

      Abstract: In this study, an adaptive neuro fuzzy interface system (ANFIS) based predictor was designed to predict the physical properties of four almond types. Measurements of the dimensions, length, width and thickness were carried out for one hundred randomly selected samples of each type. With using these three major perpendicular dimensions, some physical parameters such as projected area, arithmetic mean diameter, geometric mean diameter, sphericity, surface area, volume, shape index and aspect ratio were estimated. In in a various Artificial Neural Network (ANN) structures, ANFIS structure which has given the best results was selected. The parameters analytically estimated and those predicted were given in the form of figures. The root mean-squared error (RMSE) was found to be 0.0001 which is quite low. ANFIS approach has given a superior outcome in the prediction of the Physical Properties of Almond Nuts.

    • Authors: Servet Aras; Ahmet Eşitken
      Pages: 161 - 164
      Abstract: The physiological responses of cherry rootstocks were evaluated under moderate salinity in short term. MaxMa 14, CAB-6P and Mazzard rootstocks were treated with 35 mM NaCl solution for 1 month to assess physiological responses. Under NaCl stress, rootstocks’ physiological parameters were compared with their own control, with the greatest alterations in SPAD value, leaf relative water content (LRWC), membrane permeability and stomatal conductivity. SPAD value was reduced by 9.5, 2.17 and 2.27% in saline-treated plants of MaxMa 14, CAB-6P and Mazzard, respectively. MaxMa 14 and CAB-6P exhibited a rapid decrease in stomatal conductivity by 39.90 and 47.60%, respectively compared with their control, while in Mazzard there was a reduction by 5.28% compared with its control. Moreover, LRWC of the plants decreased by 11.24 and 13.75% in salt-treated MaxMa 14 and CAB-6P, respectively. In comparison, a lower reduction of LRWC (6.11%) was observed in NACl-treated Mazzard. As seen in the result of experiment, the inhibitory effects of NaCl were less in Mazzard compared with MaxMa 14 and CAB-6P.

  • Seed Oil Quantity and Fatty Acid Composition of Different Sea Buckthorn (
           Hippophae Rhamnoides  L.) Wild Populations in Iran
    • Authors: Ali Kuhkheil; Ali Mehrafarin; Vahid Abdossi; Hassanali Naghdi Badi
      Pages: 165 - 172
      Abstract: Sea buckthorn (Hippophae rhamnoides L.) is a valuable multipurpose medicinal plant belonging to Elaeagnaceae family. In this study, oil content and fatty acid composition of seed oil from 20 sea buckthorn wild populations of Iran were evaluated in 2014 and 2015. Oil extraction was done using n-hexane solvent in a Soxhlet apparatus and then GC analysis of fatty acid methyl esters was performed. The highest and lowest amount of seed oil content in two years were obtained from Sarein and Kejel populations, respectively (3.88 to 8.63% in 2014 and from 4.07 to 9.66% in 2015). Importance of seed oil is related to it’s highly amount of unsaturated fatty acids. Maximum content of oleic acid cis were existed in Kelavenga (21.19%) on 2014. The highest value of oleic acid trans were related to Shahrestanak (6.34%) in 2015. Maximum content of linoleic acid in 2014 were existed in Baladeh (42.03%) on 2015. The highest linolenic acid content were obtained from Dehdar (30.73%) in 2014. Factor analysis based on PCA revealed, first three components (PC1–PC3) explained 63.86% of the total variation. The first component (PC1) was contributed by some traits such as seed oil percentage, Palmitoleic acid, oleic acid trance and linoleic acid contents with about 29% of total variation. Hierarchical cluster analysis divided the populations into four main groups with high diversity. Wide range of variation across the sea buckthorn populations in seed oil traits could be exploited for selection of suitable genotypes to improvement and commercial exploitation of this plant.

  • Evaluation of Phenolic Composition and Content of Pear Varieties in Leaves
           from China
    • Authors: Xingguang Dong; Yingchun Zheng; Yufen Cao; Luming Tian; Ying Zhang; Dan Qi; Hongliang Huo; Dajiang Wang
      Abstract: In this study, we assessed the main phenolic compounds in leaves of 90 pear germplasm resources, including 26 accessions of P. bretschneideri, 24 accessions of P. pyrifolia, 40 accessions of P. ussuriensis to determine the diversity of phenolic compounds among these pear species and to analyse the relationships among the contents and profiles of phenolic compounds. The average contents of total phenolic compounds of different pear species in leaves were in the range of 17.02–21.11 mg/g. Arbutin was detected as major phenolic compound in the leaves which contributed almost 32.3% of the total amount of phenol compounds in the assayed samples, and about 86.7% of the varieties had highest arbutin content than other individual phenolic compounds. Principal component analysis (PCA) showed that P. bretschneideri and P. pyrifolia accessions were not noticeably discriminated with each other based on their phenolic content and profile, while P. ussuriensis accessions were markedly distinguished mostly according to the second principal component variation, and also wild P. ussuriensis and cultivated P. ussuriensis accessions showed obvious discriminating between each other. The specific organization of the pear species based on the accumulation of secondary metabolites showed a high consistency with the phylogenetic organization known. Partial least squares discriminant analysis (PLS-DA) showed that the phenolic composition in leaves resolved variation in difference pear species from China, and the variation was mainly attributed to four compounds. This study provides new insights into phenolic diversity of pear germplasm resources.

  • Phytochemical Screening and Biological Activity of Extract Berries of
           Black Currant ( Ribes nigrum  L.)
    • Authors: Svetlana M. Paunović; Mihailo Nikolić; Rade Miletić; Pavle Mašković; Mira Milinković; Žaklina Karaklajić-Stajić
      Abstract: The objective of this study was to identify and quantify phenolic compounds, antioxidant and antimicrobial activity in extract of berries of seven black currant cultivars (‘Ben Lomond’, ‘Ben Sarek’, ‘Titania’, ‘Čačanska Crna’, ‘Tisel’, ‘Tiben’ and ‘Tsema’). High performance liquid chromatography-diode array detector (HPLC-DAD) technique was used to establish the profile of phenolic compounds. Antioxidant properties were evaluated using different methods, including total antioxidant capacity, DPPH and hydroxyl radicals scavenging activities, as well as inhibition of lipid peroxidation. The highest amounts of phenolics (15.0 mg GAE/g), flavonoids (5.25 mg RU/g) and antioxidant capacity (12.4 mg AA/g) were found in the cultivar ‘Čačanska Crna’, whereas the other cultivars exhibited variability in the studied parameters. The fruits of black currant contained high concentrations of flavonols and phenolic acids. The main phenolic compounds were quercetin and caffeic acid. All explored extracts exhibited strong scavenging activity against DPPH radicals, which ranges from 56.19 μg/mL (‘Titania’) to 61.17 μg/mL (‘Tisel’). The antimicrobial activity was tested using broth dilution procedure for determination of the minimum inhibitory concentration (MIC). The MICs were determined for 8 selected strains. All extracts showed strong antimicrobial activity, in the range between 50.65 μg/mL and 166.38 μg/mL. Black currant fruit extract, rich in phenolic compounds and with strong antioxidant activity can be used as natural antioxidant in food and pharmaceutical industries.

  • Reduction of Cracking in Pomegranate Fruit After Foliar Application of
           Humic Acid, Calcium-boron and Kaolin During Water Stress
    • Authors: Elmira Ghanbarpour; Mehdi Rezaei; Shaneka Lawson
      Abstract: One of the primary physiological issues with cultivation of pomegranate (Punica granatum L. cv Post Sefid Darjazin) is excessive fruit cracking. Foliar applications of chemical and organic mixtures to limit or prevent pomegranate cracking were evaluated in this work. This 2 year study (2014–2015) was conducted in Darjazin, Iran and designed to evaluate the impacts of foliar application of 2 and 5 ml l−1 humic acid, 6% kaolin, and 3% Calcium-1% Boron (CB) separately or in combination. Pomegranate fruits were examined under two irrigation regimes at three time periods during the growing season. It was found that 14 day irrigation periods resulted in significantly more cracking in pomegranate than standard irrigation. Increased temperatures in 2015 contributed to higher percentages of fruit cracking as well. Foliar application of 6% kaolin significantly decreased cracking in 7 day irrigation studies while 2 ml l−1 humic acid, 6% kaolin, CB, and the combination of 6% kaolin/CB and 6% kaolin/2 ml l−1 humic acid reduced cracking under 14 day irrigation. Fruit weights significantly increased with 6% kaolin application and 7 d irrigation while 5 ml l−1 humic acid both increased pomegranate acidity and decreased the flavor index. Therefore, foliar application of kaolin and humic acid can reduce cracking in pomegranate fruit.

    • Authors: Nilda Ersoy; Osman Tekinarslan; Elif Akcay Ozgür; Ulas Göktas
      Abstract: Good Agricultural Practices (GAPs) includes agricultural techniques which environmentally-conscious, is not harmful to human and animal health, target protection of natural resources, provide traceability and food security. With these kinds of production techniques, it is aimed at agricultural production which is socially viable, economically profitable and sustainable. In this study conducted under good agricultural practices, pesticide residues in apricot fruit were investigated. The experiment was set up to have 3 replications and 15 trees in each replicate, according to randomized trial design. From the trees included in the experiment, necessary samples were taken at the harvest time and analyzes were carried out. In this study, pesticide residue levels were determined in fruit extracts with high-precision analytical instruments such as LC-MS/MS and GC-MS. A total of 385 pesticide active substances were analyzed in LC-MS/MS and 101 pesticide active substances in GC-MS in fruit extracts. In this research carried out in 2014 and 2015, samples of both years were not found to be detectable to the tolerance values of Turkish Food Codex (TFC).

  • Effects of Plant Growth Regulators on Sex Expression and Flower
           Development in Pomegranates
    • Authors: Hakan Engin; Zeliha Gökbayrak
      Abstract: The effects of external treatments with gibberellin, brassinosteroid and auxin on sexual determination and flower development in pomegranate (Punica granatum L. cv. Çekirdeksiz) were investigated. Eigth treatments with three growth regulators, viz., epibrassinolide at 0.01 and 0.1 ppm, homobrassinolide at 0.01 and 0.1 ppm, GA3 at 10 and 25 ppm, NAA at 5 and 15 ppm and control (water spray) were sprayed at the time of initiation of new sprouts. Effects of the plant growth regulators on the percent of the flowers types were not clear. Plants produced considerably more male flowers. Although no statistical importance was detected, it was clear that all growth regulators decreased bisexual flowers and increased male flowers. There were no significant effects of growth regulators on the formation of bisexual flowers at different positions in the plants. The percentage of single bisexual flower was significantly higher than terminal or lateral bisexual flower in a cluster in the control plants. Effects of the plant growth regulators on the size of the parts of the bisexual pistils were, however, found important. The smallest ovaries were obtained from 0.1 ppm HBr, base to sepal notch was the only characteristic which was not influenced by the treatments and stayed between 15 and 18 mm. Total pistil length of the bisexual flowers was greatest with EBr applications and the shortest with the HBr treatments (about 27.5 mm). Length of the style and stigma was mostly shorter, but 0.1 ppm EBr boosted it up comparably more than the rest of the applications including the control. Stigma, on the other hand, was widest in the control flowers, closely followed by all except 0.1 ppm EBr application.

  • Influence of Different Soilless Substrates to Morpho-physiological
           Characteristics and Yield Relations in Strawberries
    • Authors: Nafiye Adak; Ilhami Tozlu; Hamide Gubbuk
      Abstract: Some of the advantages of soilless production systems over conventional systems are higher yield, better pest control management and more efficient labor use. Among berries, strawberry responds quite well to soilless production systems. Major yield-affecting factors for strawberries in soilless systems may be listed as; growing medium, source and types of plantlets, density of plants and efficiency of fertigation system. The present research was conducted with strawberry plants (Fragaria x ananassa ‘Camarosa’) grown in four different media; (1) Cocopeat (C), (2) Peat (P) and (3 and 4) 1:1 mixtures with Pumice (Pu), to evaluate the effects of soilless media on marketable yield and root-shoot morpho-physiological parameters. Correlation measurements were made to assess if there is any interaction between yield and any tested morpho-physiological feature. The experiment was conducted in greenhouse, using frigo plantlets (11.6 plantlet/m2) planted in July and through 1 June of following year. Results showed that growth medium had an effect on yield, numbers of developed leaves, shoot-root dry mass, number and length of roots. Yield was correlated with these morphological features. Growth medium also had an influence on plant nutrient accumulations i. e., shoot accumulation of nitrogen (N) and potassium (K) and root accumulation of phosphorus (P) and all the micro-nutrients that with exception of boron (B). There were some interactions between yield and plant nutrient content of tissues determined by correlation analyses. The most striking were negative correlations with yield and shoot N–K amounts and positive correlation with yield and root P amount. Some positive correlations were also found between yield and copper (Cu), manganese (Mn) and zinc (Zn) contents of both shoot and root tissues. Boron (B) contents was correlated only with the root tissues. The medium which had the best overall performance for soilless strawberry production was C + Pu and should be recommended to be used with frigo plantlets of ‘Camarosa’.
