  • Morphological Variability of Berberis integerrima from Iran
    • 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.

  • Relationships Among some Pears Genotypes ( Pyrus Communis L.) Based on
           ISSR and RAPD Analysis
    • Abstract: Thirty one pears genotypes from east blacksea region were evaluated for genetic relationships by using Randomly Amplified Polymorphic DNA (RAPD) and ISSR (Inter-Simple Sequence Repeats) markers from total 70 RAPD and ISSR primer investigated, 22 could amplify clearly and consistently. Cluster analysis of the pears genotypes was performed based on data from polymorphic bands RAPD and ISSR by using Jaccard’s similarity coefficient and the Unweighted pair-group method with arithmetic average (UPGMA) clustering method. The 31 pear genotypes were classified into two major groups. Cluster A was divided into 2 subclusters: Gumushane pears and Trabzon pears. Cluster B consisted of Artvin pears. The similarity matrix values ranged between 0.105 and 0.968.

  • Seedless Berry Growth and Bioactive Compounds of cv. ‘Recel
           Uzümü’ ( V. Vinifera L.) as Affected by Application
           Doses and Times of Pre-Harvest Thidiazuron
    • 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
    • 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 ...

  • Variation in Total Phenolic Compounds, Anthocyanin and Monoterpene Content
           of ‘Muscat Hamburg’ Table Grape Variety ( V. vinifera L.) as
           Affected by Cluster Thinning and Early and Late Period Basal Leaf Removal
           Treatments
    • Abstract: Cluster thinning (CT) and basal leaf removal (BLR) are common canopy management practices used in grape growing. In recent years, novel viticultural techniques have been evolved all around the world to decrease costs of yield management, causing improvement in grape quality. The purpose of this study was to evaluate the effects of CT and early and late period BLR treatments on yield and quality components of cv. ‘Muscat Hamburg’. While BLR treatments were performing at pre-bloom (PB, early), berry set (BS), berries with pea size (PS), verasion (V), CT treatment was conducted at verasion period. Compared to Control, while the total phenolic compounds content, total anthocyanin content, free volatile terpenes content and potentially volatile terpenes content were made better by CT treatment and BLR treatments applied from berry set to verasion period gradually raised all these quality components. As a result, BLR-PB treatment from BLR treatments, which was alternative to usual cluster thinning treatment in yield controlling grapevines was especially determined as powerful tool for improving quality characteristics of cv. ‘Muscat Hamburg’.

  • The Determination of Nematode Tolerance and Seedling Performance of The
           Selected Almond ( Prunus amygdalus  L.) Genotypes in Isparta Province
           
    • Abstract: In the present study, selected almond genotypes in Keciborlu/Isparta region by Yıldırım (2007) based on late blooming and superior nut chacteristics were used to evaluate seedling growth performances and the reaction to root knot nematodes. Seeds were planted on perlite medium and stored 60 days at +4 °C in order to break seed dormancy. After germinating, seedlings were transferred to plastic pots to evaluate seedling growth characteristics and remaining seedlings were inoculated with Meloidogyne javanica and Meloidogyne incognita in order to asses resistance status of the selected seedlings. The highest germination percentage was obtained from Genotype 54 (96.1 %), the highest plant was observed from Genotype 9 (62.18 cm), the longest primary root was found from Genotype 54 (30.28 cm), the average secondary root lenght was highest in Genotype 9 (31.04 cm) and the widest root collar was observed in Genotype 33 (8.38 mm). Seedling stem diameter changed between 4.76 mm (Genoype 40) to 7.67 mm (Genotype 33). The lowest variation for stem widht was observed in Genotype 55 (0.58 %) while the lowest variation for seedling hight was found in Genotype 33 (0.50 %). Evaluated almond genotypes showed different reactions to studied nematode species, M. javanica and M. incognita. Resistant reactions of almond genotypes to nematode species were classified as susceptible, tolerant and resistant based on gal index values. Genotype 9 and 31 classified as tolerant to M. javanica while Genotype 54 classified as resistant to M. incognita.

  • Effects of Preharvest Foliar Calcium Applications on the Storage Quality
           of ‘0900 Ziraat’ Sweet Cherry Cultivar
    • Abstract: The objective of this study was to investigate effects of foliar calcium application on storage of sweet cherry. Different concentrations of CaCl2 (2.4, 3.2, and 4.0 g/l) and Ca(NO3)2 (3.4, 4.6, and 5.8 g/l) were applied six times by foliar spraying on leaves and fruits of the sweet cherry variety ‘0900 Ziraat’. Harvested fruits were packaged in 500 g plastic boxes and stored for four weeks at 0 0C and 90–95 % relative humidity. During the experiment, flesh firmness, titratable acidity value (TA), pH, total soluble solids content (SSC) ratio, and weight losses were weekly assessed. The results indicated that there were positive effects of foliar calcium applications on fruit quality coupled with improved firmness, and enhancement of TA, an additional advantage for consumer acceptability. It was found that lower concentrations of both calcium treatments were not affective. On the other hand, 3.2 g/l calcium chloride and 4.6 g/l calcium nitrate were advised. Higher concentrations (4.0 g/l calcium chloride and 5.8 g/l calcium nitrate) caused a decrease in fruit quality through deformations on the fruit surfaces, especially after the third week of storage.

  • Effects of Irrigation Frequency on Yield and Quality Parameters in Apple
           c.v. ‘Gala, Galaxy’
    • 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.

  • Effects of Plant Growth Promoting Rhizobacteria (PGPR) on Growth, Yield
           and Fruit Quality of Sour Cherry ( Prunus cerasus  L.)
    • Abstract: The sour cherry cv. ‘Kütahya’ is one of the most produced cultivars in Turkey. This study was conducted with cultivar ‘Kütahya’ cultivated on Prunus mahalep both 2010 and 2011 years. In this study, the effects of Bacillus mycoides T8 and Bacillus subtilis OSU-142 bacteria strains on yield, fruit properties and plant growth was aimed to investigate. Floral and foliar applications of T8, OSU-142 and T8+OSU-142 on sour cherry significantly increased the yield per tree, shoot length and leaf area, compared with the control. The highest shoot length was found in the T8+OSU-142 (51.74 cm) application while the least value was found in the control (46.71 cm). The yield increased from 8.229 kgtree−1 (in control) to 13.663 (T8 application) and to 11.660 kgtree−1 (T8+OSU-142 application) in average of two years. The results of the present study suggested that Bacillus T8 and Bacillus OSU-142, alone or in combination, have a great potential for the enhancement of yield and plant growth of sour cherry and therefore they have been suggested in growth promotion in sour cherry cultivation.

  • Phenological Changes of Leaf Nutrients in Vitis labrusca  L. Grape
           Grafted on Different Rootstocks in Heavy Clay Soil Conditions
    • 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.

    • 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
    • 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.

  • Evaluation of the Effect of Different Harvest Time on the Fruit Quality of
           Foşa Nut
    • Abstract: This study was carried out in Arsin (Trabzon/Turkey) in 2011. The effects of different harvest time and altitudes on the quality of the nuts have been investigated. The study was performed on Foşa hazelnut and the harvest process has been conducted at three terms, which are on normal harvest time and ten days before and after harvest time. The harvested nuts were dried in the shade on the concrete floor until their moisture content decreased to 5 %. Some properties of nuts including yield, fruit weight, internal weight, shell thickness, and protein, oleic, and linoleic acid amounts have been investigated. As evaluated all of the fruit properties it can be concluded that 11 August is the most suitable harvest date for coast zone. On the other hand, no significant differences were obtained in the point of protein, oleic, and linoleic acid amounts for different harvest time and altitudes.

  • Fruit Characteristics and Detachment Parameters of Sour Cherry ( Prunus
           cerasus L. cv. ‘Kütahya’) as Affected by Various Maturity
           Stages
    • Abstract: The variability in fruit maturity and quality has difficulties in determining the optimal harvesting maturity. Therefore, maturity stage in harvest is crucial for both fruit quality and minimizing the fruit detachment force. This study investigates the fruit characteristics and detachment parameters of sour cherry (cv. ‘Kütahya’) in terms of different maturity stages. Sour cherries were grouped into five different maturity stages by observation according to their color and dimensions. The fruit mass and dimension increased as a function of maturity stage; however, the fruit mass remained almost same after the 4th stage. The highest values of total soluble solids and titrable acid contents of sour cherry were gained in the last stage of maturity. The value of chroma of fruit outer color was higher 50 % than that of fruit inner color in the 1st maturity stage. However, it was almost same in the 5th stage of maturity. Increasing fruit maturity caused a decrease in the values of fruit detachment force ranging from 4.25 to 1.78 N, giving the coefficient of determination of 0.947. Similarly, the ratio of fruit detachment force to fruit mass, detachment stress, and specific energy decreased as the fruit maturity increased. The harvest of sour cherry is done only once in the optimum time to decrease the harvest cost. Minimizing the variability in fruit maturity throughout the tree is essential for gaining the maximum profit and lower fruit detachment force in this convenient time. Results of this study indicated that 3rd−5th maturity stages were critical for harvest. In order to attain the maximum poundage per tree and color for the market the most of the fruits should be in these stages. Therefore, appropriate management strategies that could homogenize the maturity throughout the tree should be applied.

  • In vitro Germination of Early Ripening Sweet Cherry Varieties ( Prunus
           avium L.) at Different Fruit Ripening Stages
    • Abstract: In vitro embryo culture enabled satisfactory germination of immature seeds produced in crosses from early ripening sweet cherry varieties (Prunus avium L.). Three varieties —‘Rita’, ‘Bigarreau Burlat’ and ‘Carmen’— were crossed with ‘Early Star’ as male parent. Germination rate was affected by the developmental stage of both fruit and embryo. Fruit ripening stage was a critical factor for culture infection rate that increased with maturity. In-ovule embryo culture on Murashige and Skoog medium without hormones improved the embryo size but did not increase the germination rate due to a further increase in infection rate. Ex-ovule embryo culture on Murashige and Skoog medium supplemented with BA 1 mg L−1, NAA 0.5 mg L−1, 20 g L−1sucrose, 10 g L−1 sorbitol and 6 g L−1agar during the stratification time increased embryo length. Germination was performed on Brooks and Hough medium at the 22 ± 1 °C with 16/8 h light/dark photoperiod. The highest germination rate (75 %) was reached in embryos that were 3−4 mm in length, after 30-days stratification at 4 °C. Embryos in fruits at green-yellow stage that were 3−4 mm long were morpho-physiologically developed to produce bipolar seedlings, without combined application of embryo culture and micropropagation.

  • Breeding Perennial Fruit Crops for Quality Improvement
    • Abstract: Fruits play a crucial role in human diets and as a commercial commodity in trade. The consumers have considered fruit quality as the most important criteria that decides its acceptability. Fruit quality-based overall acceptability determines the success of any breeding programme, as a number of improved varieties with desired traits including resistance to stresses could not be popularized due to their poor quality fruits. However, breeding for quality improvement in perennial fruit crops is hampered by a number of limitations including large size of the plant, long juvenile phase and environmental problems (e.g. fruit drops due to natural calamities). Besides, fruit quality is a polygenic trait, which is quantitatively inherited and thus making breeding programme complicated in quality improvement of fruit crops. Several attempts have been made to improve the quality characters in annual staple crops, however this aspect is conveniently ignored in case of perennial fruit crops. A balanced approach combining conventional and non-conventional breeding techniques could help in addressing this issue. The biotechnological approaches provide precision, reliability and are considered to reduce the breeding cycle in long duration crops. Efficacy of approaches like marker assisted selection, candidate gene, genomics, trangenics, cisgenics has shown to be advantageous when dealing with cumbersome crops. This review would focus on problems in fruit breeding and present status of different breeding approaches for fruit quality improvement in fruit trees.

  • Interaction of Crop Load and Irrigation on Yield, Fruit Size, Color and
           Stem-end Splitting Ratio of Apple c.v. ‘Gala, Galaxy’
    • Abstract: In this study, the interaction between crop load and irrigation level on yield, fruit size, skin color and stem-end splitting fruit ratio in the apple cultivar ‘Gala, Galaxy’ grafted on rootstock M9 were investigated. Six irrigation programs were applied during the whole growth season: deficit irrigation (rates of 0.25 kc, 0.50 kc, 0.75 kc), full irrigation (rate of 1.00 kc), excess irrigation (rate of 1.25 kc) and non-irrigation (rates of 0.00 kc of “Class A” pan evaporation coefficient). Four crop loads in each irrigation application were performed by hand thinning after the June drop as a- a low crop load (3 fruits cm−2 TCA), b- a medium crop load (5 fruits cm−2 TCA), c- a heavy crop load (7 fruits cm−2 TCA), and d- an un-thinned crop load (> 7 fruits cm−2 TCA). The total tree yield increased with crop load and irrigation levels. Fruit size was significantly increased by the low crop load. Irrigation increased the fruit size compared to non-irrigation treatment. Further 0.75 kc, 1.00 kc and 1.25 kc irrigation treatments significantly increased the fruit length. Irrigation reduced the fruit flesh firmness. While the low crop load increased the skin red color, it decreased the fruit skin brightness. The yellowness of skin decreased with increasing in the irrigation amount. Irrigation reduced the skin brightness and yellowness, but it increased red color. Crop load and irrigation significantly affected the stem-end splitting fruit ratio. While the splitting fruit ratio increased with a decrease in the crop load, it decreased with an increase in irrigation amount, relatively. Consequently, the low and medium crop load treatments would be beneficial to increase the ratio of marketable fruits without any significant losses in yield for ‘Gala’ apple, especially under 0.75 kc deficit irrigation treatment.
