THE INFLUENCE OF SPRAYS OF GIBBERELLIC ACID (GA3) AND AMINOETHOXYVINYLGLYCINE (AVG) ON FRUIT ABSCISSION, FRUIT RIPENING AND QUALITY OF TWO SWEET CHERRY CULTIVARS

Sweet cherry (Prunus avium L.), originated around the Caspian and Black Sea, is an important fruit tree species of economic interest, and hence, breeding and conservation are requested (. Genetic analysis at the molecular level can be used effectively to study molecular polymorphism existing between intraspecific and interspecific tree species and phylogenetic relationships between them and their hybrids. The purpose of this study was to characterize and determine genetic relationships among the sweet cherry native genotypes belonging to Fruit Research & Development Station Bistrita, Romania, using RAPD markers. To eliminate the existence of possible synonyms from national romanian collection, we collect four Van cultivars, from four different national collection. For molecular analysis of the 16 varieties of sweet cherry were considered 13 RAPD primers selected from the literature. They were later used to determine the genetic variability at the molecular level using PAST program, and the dendrogram was generated based on Jaccard’s genetic distance. The dendrogram constructed by PAST software. The quantity and quality of the DNA obtained was suitable to achieve PCR amplification step. Only seven out of the 13 RAPD primers have generate polymorphic bands. The rest of seven were monomorphics. The most polymorphic primer was OPB10 which generated 11 bands from which 100% were polymorphic.Seven RAPD primers generated a high level of polymorphism which allowed to divide these cherry varieties into two groups according to their genetic geographical origin and the pedigree.

AbstractThe study was performed at the Experimental Station of Agriculture - Khan Krum in the period 2018-2019. The experimental plantation was established in 2001, the early Bigareau Burlat, middle early Bing and the late Germersdorfer and Van were tested. The planting material was produced on a mahaleb rootstock. The distance of planting was 6 meters interrow spacing and 5 meters intrarow spacing. The experiment was based on three replications each of them reported on a separate tree. When analyzing the frost percentage of flowers, 400 blossoms were taken from three levels of the crown of each tree, the same number of fruits were taken to determine the cracking percentage. Percentage of damaged blossoms, yield kg/ha and percentage of fruit cracking as a result of fallen rains during harvest were established. The purpose of the study is to investigate the influence of abiotic factors on the yield and quality of four sweet cherry cultivars. In this regard, the frost percentage in the range of values was 67,3 - 100%. Bigareau Burlat yield was not obtained, and it was relatively low from Germersdorf and Bing (20,1 - 24,6 kg/ha) at Van 84,6 kg/ha. The number of cracked fruits due to fallen rains during harvest was relatively high in Van and Bing (39,8 - 47,4%), while in the Germersdorf cultivar it was lower - 21,2%.

The objective of this study was to determine the effects of gibberellic acid (GA3) applications on fruit quality of ‘0900 Ziraat’ sweet cherry (Prunus avium), a low cropping and a large-fruited variety. ‘0900 Ziraat’ trees were sprayed with 0, 15, 20, and 25 ppm GA3, when the fruit were at their straw-yellow color stage. Fruit quality was evaluated at harvest in terms of size, firmness, pedicel length, and soluble solids content (SSC) to determine the optimum application. Fruit treated with GA3 were significantly larger and firmer than the controls. There were no differences in fruit firmness within the different levels of GA3 treatment; however, fruit treated with 20 and 25 ppm GA3 were significantly larger than the fruit treated with 15 ppm GA3. Trees treated with the optimum concentration of GA3 (25 ppm) in two different locations yielded fruit with 13.4% and 14.1% greater weight and 38% and 25% higher firmness. GA3 treatments did not affect pedicel length. The effect of GA3 application on SSC was complex; there was a significant interaction between GA3 and location. Being firmer than the controls, the GA3-treated fruit could be harvested at a later date than the controls.

Sweet Cherry Cultivars

Starting with 1981, the objectives of the breeding programmes in the Research Station for Fruit Growing (RSFG) Iaşi, Romania, took into consideration the on-going improvement of the sweet cherry assortment with cultivars having fruit-bearing precocity, with great productions, self-fertile, with decreased trees’ vigour, crown compactness, resistant to anthracnose, monilia, frost and fruit’s cracking, flowering lateness, superior quality of the fruits and ripening time at the extremities of the sweet cherries’ maturation season. As a result of the breeding programmes that took place up till present at RSFG Iaşi, 28 new sweet cherry cultivars, obtained through controlled hybridization, free pollination and conservative clonal selection, were homologated during 1994-2017. The present results refer to a study led during 2015-2017, having as biological material nine sweet cherry cultivars (‘Cetăţuia’, ‘Cătălina’, ‘Golia’, ‘Bucium’, ‘Ştefan’, ‘Iaşirom’, ‘Oana’, ‘Radu’ and ‘Ludovan’) obtained through controlled hybridization. The comparision of the cultivars has been performed versus their genitors ‘Van’ (♀) and ‘Boambe de Cotnari’(♂). There have been taken observations and determinations concerning the trees’ vigour, resistance to frost and anthracnosis, the main growing and fructification phenophases, physical and chemical treats of the fruit. The highest values regarding fruit’s weight (7.5-8.9 g) have been recorded for the ‘Ludovan’, ‘Bucium’, ‘Ştefan’, ‘Iaşirom’ and ‘Golia’ cultivars, while the values of the soluble substance content have been between 15.20-19.25 °Brix, the titratable acidity has been between 0.455-0.764 g malic acid 100 mL-1 of fresh juice and the total content of polyphenols has recorded values between 97.41-574.95 mg GAE 100 mL-1 of fresh juice. The hybridization between ‘Van’ and ‘Boambe de Cotnari’ has allowed the obtaining of valuable cultivars, that got remarked by earliness (‘Cetăţuia’, ‘Cătălina’), decreased trees’ vigour (‘Ştefan’, ‘Golia’), particular quality of the fruits (‘Ludovan’, ‘Iaşirom’, ‘Golia’, ‘Bucium’, ‘Ştefan’, ‘Oana’, ‘Radu’) and resistance to diseases and frost (‘Bucium’, ‘Iaşirom’).
