  • Yield and Quality Response of Young ‘Gala, Galaxy’ Trees under
           Different Irrigation Regimes
    • Authors: Yusuf Ucar; Abdullah Kadayıfcı; Mehmet Atilla Askın; Abdullah Kankaya; Ulas Senyiğit; Fatma Yıldırım
      Pages: 159 - 167
      Abstract: Abstract This study was conducted in 2007–2008 to determine the effects of different irrigation regimes on yield, quality and water-yield relationships of young dwarf ‘Gala, Galaxy’ apple trees in Isparta-Turkey. Irrigation water was applied based on a ratio of class A pan evaporation (rates of 0.0 (kcp0), 0.25 (kcp1), 0.50 (kcp2), 0.75 c (kcp3), 1.00 (kcp4) and 1.25 (kcp5)) with 5-day intervals. The effects of irrigation regimes on yield and fruit weight were statistically significant. Seasonal evapotranspiration was measured as 246.5–608.2 mm and 289.3–631.9 mm in 2007 and 2008, respectively. Water use efficiency lead to a yield ranging from 0.0023 to 0.0055 t ha−1mm−1 and from 0.0033 to 0.0111 t ha−1mm−1 and irrigation water use efficiency varies from 0.0009 to 0.0073 t ha−1mm−1 and from 0.0045 to 0.0186 t ha−1mm−1 in 2007 and 2008, respectively. The annual average yield response factor, ky, was 1.22. As a result of the research, it was concluded that the irrigation schedule for the 0.75 kcp3 treatment, applying 0.75 of evaporation from class A pan, could be used in the irrigation of young dwarf apple trees without evident reduction in yield and that high water use efficiencies could be obtained.

    • Authors: Adem Gunes; Metin Turan; Nurgul Kitir; M. Sefik Tufenkci; Kerim Mesut Cimrin; Ertan Yildirim; Sezai Ercisli
      Pages: 177 - 184
      Abstract: Abstract Deficiency of Boron (B) is widespread in the many parts of region of Turkey. So, the effects of boron and plant growth promoting bacteria (Bio-B) on the fruit yield, antioxidant enzyme activity and plant freeze injury of strawberry cv. Fern were investigated under field conditions between 2013 and 2014. The experimental plot was a completely randomized design with 4 replicates. Control and Bio-B were used as fertilizer agent in the experiment. Bio-B fertilizer was applied in three methods as soil, foliar and soil + foliar application methods to strawberry plants. Data through 2 years showed that the use of Bio-B significantly increased fruit yield, antioxidant enzyme activity and decreased freeze injury of strawberry leaf. Soil + foliar applications of Bio-B fertilizer increased to fruit yield compared to the control by 55.91 %. However, foliar application of Bio-B fertilizer increased to catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) enzyme activity compared with the control treatment 41.86 %, 48.99 %, and 26.59 %, respectively and decreased freeze injury of strawberry leaves 27.41 %. Overall, the results of this study suggest that Bio-B fertilizer application have the potential to increase the yield, antioxidant enzyme activity and decreased freeze injury of strawberry plants under field conditions.

  • Phenotypic and Bioactive Diversity on Medlar Fruits (Mespilus
           germanica L.)
    • Authors: Mustafa Akbulut; Sezai Ercisli; Tunde Jurikova; Jiri Mlcek; Sadiye Gozlekci
      Pages: 185 - 191
      Abstract: Abstract Mespilus germanica, known as the medlar, is a large shrub or small tree. The fruit has been cultivated since Roman times, and is unusual in being available in winter, and in being eaten when bletted.  In this study twelve medlar (Mespilus germanica L.) genotypes were harvested at commercial maturity stage (skin brownish, pulp white, fruit hard) from Rize provinces located eastern black sea region and were analyzed for their some important fruit phenotypic (fruit mass, shape index, fruit firmness, ostiole diameter and fruit flesh ratio) and bioactive characteristics (total phenolic content, total antioxidant capacity, vitamin C and phenolic compounds). A wide variation among genotypes on most of the searched parameters was found. Fruit mass and flesh ratio varied from 12.3 g (KRD-1) to 23.6 g (KRD-8) and 83.6 % (KRD-2) to 93.0 % (KRD-4) indicating high variability among genotypes. The total phenolic contents of twelve medlar genotypes varied from 157 to 227 mg gallic acid equivalent in 100 g fresh weight basis. Chlorogenic acid, rutin and p-coumaric acid were dominant in medlar fruits.

  • Concurrent Ex vitro Rooting and Hardening in Ney Poovan Banana ( Musa AB):
           Effect of Carbon Sources and their Concentrations
    • Authors: P. Bohra; A. A. Waman; B. N. Sathyanarayana; K. Umesha
      Pages: 193 - 198
      Abstract: Abstract Mass multiplication of non-Cavendish group of bananas has been limited due to non availability of reliable multiplication protocol and higher cost of production. The process of root induction and hardening are considered to be the most capital and labour intensive activities in micropropagation of any species. Carbon sources being one of the prime components governing the ex vitro survival of the plants need to be studied to maximize the success rate. Present is an attempt to study the effect of kind and concentration of carbon source on concurrent ex vitro rooting and hardening (CEVRH) in Ney Poovan banana. The results revealed that kind and concentration of carbon source present in the nutrient pool at the time of multiplication had a significant effect on the ex vitro performance of the plantlets. Better ex vitro rooting and hardening performance was exhibited by the shoots obtained from glucose (2 %) supplemented medium. Though rooting percentage was reduced in this treatment, considering the superior performance of the plantlets, it could be recommended to the commercial units for large-scale propagation of Ney Poovan banana plants. The concept of simultaneous rooting and hardening could be a boon for the varieties showing poor multiplication rate resulting in their higher cost of production.

  • EUFRIN Tagung in Porto 2016 – Themen von Ausdünnung
           bis Stippigkeit
    • Authors: M. Blanke
      Abstract: Zusammenfassung Der Beitrag berichtet vom diesjährigen Treffen der EUFRIN-Ausdünngruppe in Porto im März 2016 mit folgenden Ergebnissen 1) Die Mehrzahl der Vorträge beschäftigte sich mit dem neuen Ausdünnprodukt BrevisTM zur Fruchtausdünnung im 8–10 mm Stadium bei Apfel (und Birne); die Wirkung beruht auf einer Photosynthesehemmung; die Zulassung ist in den meisten europäischen Ländern bereits erfolgt oder beantragt. 2) In Vorversuchen wurde die Ethylenvorstufe ACC (1‑Aminocyclopropancarbonsäure) zur Ausdünnung sowohl von Kern- als auch Steinobst auf 3 Kontinenten erprobt. Im späten 18–20 mm Fruchtstadium, nach der empfindlichen Zeit für Berostung, führte ACC bei Apfel zu dem gewünschten Fruchtfall verbunden mit leichtem Blattfall, einer Photosynthesehemmung in Abhängigkeit von der Konzentration und einer Alternanzbrechung. 3) In einem ersten, einjährigen Experiment an der Cornell Universität erhöhte S-ABA (Abscisinsäure) den Calciumgehalt der Frucht von 3 auf 5 mg/100 g FM und verminderte damit die Stippigkeit bei der amerikanischen Clubsorte ‘Honeycrisp’. Allerdings waren dazu 5 Anwendungen in 10-tägigem Abstand nach der Blüte notwendig und damit relativ aufwendig und teuer und sowohl mit leichten Blattvergilbungen, in Abhängigkeit von der Konzentration von S‑ABA, als auch mit 10–15 % kleineren Früchten verbunden. Weitere Forschungsergebnisse werden zeigen, welche Versuchsmittel sich für unsere Sorten und unser Klima eignen und dann auch zur Registrierung kommen.

  • Biodiversity in Indigenous Germplasm of Pyrus from Pakistan Based on
           Phenotypical and Morphological Traits
    • Authors: Maqsood Ahmed; Muhammad Akbar Anjum; Sajjad Hussain; Shaghef Ejaz; Shakeel Ahmad; Sezai Ercisli
      Abstract: Abstract A comprehensive analysis of various horticulturally important morphological traits of sixty pear accessions located in five districts of Azad Jammu and Kashmir (Pakistan) was carried out. Several qualitative and quantitative traits were investigated in situ and after the harvesting of leaf and fruit samples. The rich diversity was observed for qualitative traits (i. e. growth habit, blooming time, intensity of flowering, fruit setting, ripening time, productivity, and fruit shape and color) among pear accessions. As for the quantitative traits, significant variation was observed for leaf area (8.96–27.17 cm2), flowering duration (11–24 days), fruit weight (68.1–322.3 g), average fruit length (2.68–9.87 cm) and average fruit width (1.82–8.12 cm) between pear accessions. Based on qualitative and quantitative data, two dendograms were constructed by using cluster analysis which separated pear accessions into three distinct groups. The cluster analysis showed considerable differences between the accessions for qualitative and quantitative traits. Furthermore, a close association between accessions was noted inside the clusters for qualitative and quantitative traits. The results showed rich diversity and similarity between the pear accessions and needs further assessment at molecular level to elucidate their phylogenetic relationship.

  • Quantification of Leaf Water Potential, Stomatal Conductance and
           Photosynthetically Active Radiation in Rainfed Hazelnut
    • Authors: Selçuk Özmen
      Abstract: Abstract Hazelnut (Corylus avellana L.) is mostly grown in rainfed condition in Turkey as well as other some countries in the world without more yield reduction. However, there is not enough information about how to give yield without more reduction in rainfed hazelnut orchard. In an endeavor to search this question, quantifications of leaf water potential (LWP), stomatal conductance (gs) and photosynthetically active radiation (PAR) of hazelnut tree were investigated in rainfed hazelnut orchard in the summer of 2013 and 2014. Additionally, possible effects of those quantifications on rainfed hazelnut trees vs. soil water content (SWC) was investigated. Results of this study exhibited that yearly ET (evapotranspiration) of rainfed hazelnut trees was higher in 2014 than 2013 even though seasonal ET of rainfed hazelnut trees was higher in 2013 than 2014. Hence, yield, LWP and gs were higher in 2014 than 2013 but PAR and SWC (even all the study season) were mostly higher in 2013 than 2014. Moreover, relationships of LWP, gs and PAR and responses of LWP, gs and PAR to SWC were non stronger. These differences could be attributed differences of climate variability such as precipitation and temperature during the observed period throughout the season in the studied years. However, rainfed hazelnut trees may be required supplement irrigation in dry summer, such as year of 2013, to avoid summer water stress. Finally, it can be concluded that hazelnut trees can be grown well and give normal yield for the areas which have about 950 mm precipitation.

  • Effect of Storage on Textural and Sensory Properties of Czech Apple
           Cultivars
    • Authors: Martin Král; Martina Ošťádalová; Bohuslava Tremlová
      Abstract: Abstract Sensory and texture profile analysis are a major component of consumer preference of quality in apples. The objective of the study was to investigate textural and sensory changes during storage. Six different apple cultivars grown in Czech Republic, harvested in 2014, were studied. Fruits were assessed within a day of harvest after overnight storage at room temperature (20 °C), and after stored in normal atmospheres at 3 °C for two different periods, 30 and 90 days with a relative humidity of approximately 95 %. Juiciness was found to be a key parameter of apple sensory analyses. The most relevant textural profile marker, which significantly decreased in all cultivars during storage, was hardness. The first principal component (PC1) described 40.1 % of the variation amongst samples the second (PC2) 18.3 % and third (PC3) 16.0 %. Principal component analysis illustratively divided all the studied cultivar in storage time according sensory and texture descriptors and explained relationships between lots of variables affecting apple quality.

  • Investigating Root Density of Plum and Apple Trees Grafted on Low-Vigor
           Rootstocks to Improve Orchard Management
    • Authors: Cristian Paltineanu; Silvia Nicolae; Nicolae Tanasescu; Emil Chitu; Sergiu Ancu
      Abstract: Abstract Plum and apple trees are the most widely spread fruit trees in south-eastern Europe. The main purpose of this paper is to characterize the spatial distribution of roots in medium and course textured soils to improve orchard management. ’Stanley’ plum cultivar grafted on Saint Julien A semi-dwarf rootstock and ’Topaz’ apple cultivar grafted on M.9 dwarf rootstock were studied in a temperate climate and medium and course textured soils. The trench technique was used. There was an intense concentration of roots near the trees and the roots did not occupy the whole soil space between tree rows. The finest tree roots in both species were prevalent. Root density was higher in tree rows versus inter-rows. Both the inter-row and in-row distances can be reduced to increase tree density if light penetration into canopy is sufficient. When a full irrigation regime is applied, a soil depth of 0.8 m would be sufficient for water application, and soil depths of 0.4 to 0.6 m would be recommended for deficit irrigation; water and fertilizers should only be applied over the surface area covering most of the roots. When a more strict control on root activity is desired, the tree roots could be cut vertically at 0.5–0.8 m distance from tree rows. The results could also be used in regions and countries with similar soil texture and climate conditions.

  • Cherry 2016 – Abschlusskonferenz des EU Projektes COST Cherry FA 1104 im
           Anbaugebiet der Tragana Rodochori-Kirsche in Nordgriechenland
    • Authors: M. Blanke
      Abstract: Zusammenfassung Die Abschlusskonferenz des vierjährigen COST Cherry FA 1104 Projektes fand in Griechenland statt, dem nach Polen, Italien und Spanien viertgrößten Kirschproduzenten der EU. Höhenlagen um 600 m sorgen in Makedonien (40°N) für ausreichend Kältestunden (1200 Chilling Hours), um die frühe Blüte bereits Anfang April zu induzieren; Honigbienen dienen zur Bestäubung. Die Kirschen reifen vom 25. Mai bis 15. Juni und werden auf fruchtbarem Boden ohne Frostschutz und ohne Folientunnel sowohl mit Lokal – als auch internationalen Sorten und früher großen Bäumen, heute auf Gisela 6 oder Piku angebaut. Lokale Baumschulen sorgen für Pflanzmaterial und Gewebelabors für Mikrovermehrung der Kirschunterlagen. Vor 50 Jahren – 1961 – wurde aus der ehemaligen Rebschule in Naoussa das Obstbauinstitut zur Forschung und Fortbildung gegründet, das sich seit 1970 auch mit Kirschen beschäftigt. Von den 60.000 t Kirschernte werden 13–17 % (8–10.000 t) vornehmlich nach Europa bzw. bis zum Embargo bzw. bis einschl. 2014 6000 t nach Russland exportiert. Diese Premiumware für den Export wird z. T. aufwendig von Hand ausgedünnt und erzielt Abgabepreise von 2–3 €/kg bei Vermarktung einer Genossenschaft in Naoussa als „Tragana-Kirschen aus Rodochori“, einer von der EU geschützten Herkunftsbezeichnung.

  • Morphological Variability of Berberis integerrima from Iran
    • Authors: Abbasali Jannatizadeh; Abdollah Khadivi-Khub
      Abstract: Abstract Barberry is a valuable medicinal plant that belongs to family Berberidaceae. In the current research, phenotypic variations of 34 individuals of wild barberry (Berberis integerrima) were evaluated. Significant phenotypic diversity was detected between the studied accessions based on morphological traits. Significant correlations were found for variables related to seed and berry, so that seed quantity, seed width, seed weight and seed length were positively correlated with berry quantity, berry weight, skin bloom and berry length, respectively. Leaf length was in significant positive correlation with berry shape, berry skin bloom, seed length, and seed weight and in negative correlation with seed quantity. Principal component analysis showed that 77.75 % of the phenotypic variability was explained by all components for the studied individuals. Variables such as seed length, width and weight, berry length and weight, spine length, leaf length, berry quantity, and seed quantity were predominant in the first three components and contributed most of the total variation. The present results have an important implication for characterization, improvement and conservation of barberry germplasm.

  • Seedless Berry Growth and Bioactive Compounds of cv. ‘Recel Uzümü’ (
           V. Vinifera L.) as Affected by Application Doses and Times of Pre-Harvest
           Thidiazuron
    • Authors: Demir Kok; Erdinc Bal
      Abstract: Abstract The purpose of this research was to appreciate the impact of the synthetic cytokinin, well known as thidiazuron (TDZ) on seedless berry quality of cv. ‘Recel Uzümü’. Three concentration levels including 0, 5 and 10 mg/L were applied on the grapevines during different phenological stages of grapevine such as Time 1: beginning of berry stetting, Time 2: berries pepper corn size and Time 3: berries pea size. While TDZ application times had no impacts on cultivar characteristics, it was determined that the application doses of TDZ had major impacts on yield and quality components of cv. ‘Recel Uzümü’. Consequently, ascending TDZ doses increased berry and cluster size and led to decreases in total soluble solids content, total phenolic compound content, total anthocyanin content and p-value of grape juice regardless of TDZ application time. The most effective TDZ dose was 10 ppm for improving berry and cluster size in cv. ‘Recel Uzümü’.

  • Bioindikatoren für den Dormanzstatus bei Obstgehölzen
    • Authors: Laura Hillmann; Heiko Kaufmann; Michael Blanke
      Abstract: Zusammenfassung Im Rahmen einer Bachelorarbeit wurde in einem Übersichtsreferat die Literatur zu potentiellen Bioindikatoren für den aktuellen Dormanzstatus eines Obstbaumes im Winter zusammengestellt und bewertet. Die Thematik steht sowohl in Zusammenhang mit den Chillingmodellen zur Aufnahme der aktuellen Temperatursummen (0–7 °C) im Winter als auch als Voraussetzung für kulturtechnische Maßnahmen im Obstbau, um die Blüte einzuleiten. Potentielle Bioindikatoren ließen sich in 10 Hauptgruppen unterteilen: Veränderungen der Knospe von Ende der Paradormancy bis zu Beginn der Ecodormancy in der 1) Morphologie, 2) Atmungsrate, 3) im Wassergehalt; 4) Membran; 5) Source: Sink- Beziehung bzw. Zellkommunikation, 6) von Kohlenhydraten; 7) von Polyaminen, 8) von Phytohormonen und 9) der Expression der TFL1- und Ft sowie 10) der DAM (Dormancy associated MADS-Box) Gene. Die Literaturrecherche hat gezeigt, dass 1) makroskopische und mikroskopische Veränderungen, z. B. Knospenschwellen auftreten, 2) die Atmung der Knospen im Winter sich während der Endodormancy kaum veränderte, aber am Anfang des Frühlings zur Voraussage des Blühzeitpunktes sowie der Anzahl der Knospen diente; 3) der relative Wasserhaushalt (RWC) in der Winterruhe der Obstgehölze (Dormanz) sich änderte, d. h. a) in den Knospen während der Vorruhe (Paradormancy) der Anteil freien Wassers abnimmt und anschließend die Knospen während der Endodormancy gebundenes Wasser enthalten, b) die Synthese und Aktivität der Dehydrine (hydrophile Proteine) induziert wird, langsam abnimmt und erst bei Erreichen von warmen Temperaturen zum Erliegen kommt; 4) bei den Membranveränderungen bzw. im Informations- und Signalaustausch von Zelle zu Zelle (‘Zellkommunikation’) die Plasmodesmen in Dichte und Durchlässigkeit z. B. für den Botenstoff Ca 2+ abnehmen und Zellwandverschlüsse an Plasmodesmen unter Wirkung von Kurztagbedingungen entstehen , sodass kein Signalaustausch mehr möglich ist und das Wachstum eingestellt wird. Erst wenn der Einfluss des Chillings den Abbau dieser Zellwandverschlüsse ermöglicht, kann symplastischer Transport von Signalmolekülen, Hormonen und Proteinen stattfinden; 5) bei den Kohlenhydraten a) der Saccharosegehalt in der Winterruhe (Endodormancy) am höchsten ist und zum Frühling hin zur Ecodormancy-Phase abnimmt, b) Saccharose bei frostfreien Temperaturen im Xylem aus der Wurzel in die Knospe verlagert wird, c) der Stärkegehalt durch Hydrolyse abnahm und gleichzeitig der Glukosegehalt (bzw. Monosaccharidgehalt) anstieg; 6) im Stickstoffwechsel der Proteingehalt in der Paradormancy und der Aminosäuregehalt (z. B. Prolin) während der Endodormancy zunehmen; 7) mit zunehmendem Chilling der Gehalt an Polyaminen während der Winterruhe (Endodormancy) bis zum Beginn der Ecodormancy-Phase z. B. bei Reben ansteigt; 8) bei den Phytohormonen der Gehalt an Gibberellinen (GA 4 ) und Cytokininen eine Rolle spielt und der Abscisinsäuregehalt (ABA) nach Kälteeinwirkung abnimmt und Gibberellinapplikation am Ende des Winters die Dormanz brechen kann; 9) ca. 20 Gene up- und ca. 30 Gene down-reguliert werden; das blütenhemmende Gen TFl-1 (Terminal Flower locus)-1 z. B. bei Nashibirnen am höchsten während des Chillings bzw. der Endodormancy im frühen Winter exprimiert wurde und vermutlich das Chillingbedürfnis erhöht, während sich die Expression der blütenfördernden FT (Flowering Locus T) -Gene während des Forcings erhöhte, 10) die Expression der Gene DAM 1 und 4 aus der MADS-Box und ...

  • Effects of Irrigation Frequency on Yield and Quality Parameters in Apple
           c.v. ‘Gala, Galaxy’
    • Authors: Yusuf Ucar; Abdullah Kadayıfcı; Mehmet Atilla Aşkın; Abdullah Kankaya; Ulaş Şenyiğit; Fatma Yıldırım
      Abstract: Abstract This study was conducted in 2007 and 2008 in order to determine the effects of irrigation frequency on the yield and quality parameters of dwarf trees of the apple cultivar ‘Gala, Galaxy’ in the first and second year of cultivation. Irrigation water was applied at 3‑, 5‑, 7‑, and 10-day intervals as much as the amount of water consumed from the field capacity. Statistical analysis revealed that the effects of irrigation frequency on yield were significant. Since the trees used in the experiment showed mainly vegetative growth, the effects of irrigation frequency on the fruit quality characteristics varied. Irrigation water amount was applied as 355.7–446.5 mm and 359.2–538.9 mm to the experimental treatments in 2007 and 2008, respectively. The evapotranspiration measured was in the range 400.7–491.5 mm in 2007 but in the range 440.2–600.5 mm in 2008, while the yields in the same years ranged from 1.54 to 2.84 t ha−1 and from 2.61 to 6.06 t ha−1. Water use efficiency varied between 2.40 and 4.80 t ha−1mm−1 in the first year of the experiment but between 3.45 and 7.08 t ha−1mm−1 in the second year. The I2 treatment, in which the highest yield and water use efficiency were recorded in both years of the experiment under the experimental conditions, was determined as the irrigation scheduling.

  • Phenological Changes of Leaf Nutrients in Vitis labrusca  L. Grape
           Grafted on Different Rootstocks in Heavy Clay Soil Conditions
    • Authors: Bülent Köse; Ayhan Horuz; Güney Akınoğlu
      Abstract: Abstract The present study was conducted to determine the phenological changes in leaf nutrient contents in 10-years Vitis labrusca L. grapes grafted on 140Ru, 5BB and 5C rootstocks. In the experiment, changes of leaf macro and micro element contents from bud burst to post harvest period were investigated in the heavy clay soil conditions. Nutrient contents of leaf blades showed varied depending on the phenological stages and rootstocks (P < 0.01). P, K, Mg and Ca levels of leaf blade exhibited significant differences based on rootstocks and phenological periods between blooming and veraison. While Zn level was obtained sufficient on 5BB of grafted grapevines, it was found to be insufficient in grapevines grafted on 140Ru and 5C rootstocks. In general, grapevines were found insufficient for P, K and Mg nutrients. Total chlorophyll contents of leaves were found at high in the blooming period. Although the highest chlorophyll contents were found in the blooming period, it was determined at the lowest through to harvest. In the study, 5BB rootstock was evaluated to be favorable in terms of nutrient uptake.

           under subtropical conditions of India
    • Authors: Parmeshwar Lal Saran; Ravish Choudhary; Ishwar Singh Solanki; Sezai Ercisli
      Abstract: Abstract The effect of temperature on germination and days taken for germination was evaluated in Carica papaya cvs., ‘Pune selection-3’ and ‘Pusa Dwarf’. The highest average seed germination per cent was observed in the month of July (96.8 and 93.0 %), followed by August (94 and 88.5 %), whereas the lowest average seed germination was observed in the month of January (44.2 and 36.8 %) in ‘Pune selection-3’ and ‘Pusa Dwarf’, respectively. Minimum number of days (5.17 and 6.33) was observed for germination in the month of July, whereas the maximum number of days (29.5 and 31) was taken in the month of January in both the cultivars, respectively. The average highest germination and seedling height was observed at temperature 29.8 °C and 29.5 °C during July and August, respectively, whereas the lowest was observed at temperature 14 °C and 15.9 °C during January and December, respectively. The optimum time for nursery sowing was July to August for autumn season crop under subtropical conditions of India.

  • Effects of 22S, 23S-Homobrassinolide and Gibberellic Acid on Occurrence of
           Physiological Disorders and Fruit Quality of ‘Summit’ and ‘Regina’
           Sweet Cherries
    • Authors: Hakan Engin; Zeliha Gokbayrak; Mustafa Sakaldas
      Abstract: Abstract Plant growth regulators play a vital role in fruit growth and development. However, effects of compounds belonging to the group of brassinosteroids have not been fully investigated in sweet cherries. One relatively new and one commonly applied growth regulator, 22S, 23S-Homobrassinolide and GA3, respectively, were tested on ‘Summit’ and ‘Regina’ sweet cherries to determine the effects on fruit quality and physiological disorders. The substances were applied with a handgun sprayer at full bloom and at the beginning of fruit development (shuck split) for a 2-year period. GA3 was applied at the concentrations of 25, 50, 100 mgL−1 and 22S, 23S-Homobrassinolide at 0.05, 0.1, 0.5 mgL−1. A combined application of 100 mgL−1 GA3 + 0.1 mgL−1 22S, 23S-Homobrassinolide was also applied. Effects of GA3 and 22S, 23S-Homobrassinolide on fruit weight and size were evident for the concentrations applied and between the seasons for both of the cultivars. Combination of the both growth regulators and 100 mgL−1 GA3 alone produced longer fruits compared to the control trees in ‘Regina’. The 22S, 23S-Homobrassinolide applications increased the firmness of the flesh slightly, but not to a great degree, compared to the GA3 applications alone. The brightness of the red color was better with GA3 applications in ‘Summit’ and ‘Regina’. Brassinosteroid caused the fruits to have comparably dull red color. Total soluble solid contents of the cultivars were influenced by the substances and the year of the application. Stem resistance to separation from the fruit was under the influence of both treatments and seasons. In general, 22S, 23S-Homobrassinolide provided better stem resistance than the GA3 applications. There were no effects of the substances on the development of physiological disorders.
