The Effect of Adding Organic Residues, and Foliar Spray with Boron and Zinc on Some Soil Characters, Fruitlets Ratio, and Some Fruit Qualitative Traits in Starking delicious Apple Cultivar in Sweida

The study was carried out in apple orchard and at the laboratories of Agricultural Scientific Research Center, and Pome and Grapevine Division in Sweida (GCSAR), Syria, during the growing seasons of 2015 and 2016 to study the effect of organic residues, and boron and zinc addition on some soil characters, fruit set ratio and some fruits qualitative traits in Starking delicious apple cultivar in Sweida.

The Effect of Climatological Conditions on Phenological stages of Sweet Cherry (Prunus avium L.) Rosaceae in two regions of Syrian coast

The study has been done in many farms which are producing sweet cherry in Lattakia during the season (2014-2015). This research focuses on study timing of phonological stages of sweet cherry in two regions (sluonfa , aen alhaeat) in Lattakia ciety and studies the effect of some climatological conditions like temperature and rain on this plant . The result of this study revealed clear variation in the climatological conditions between the two regions under study. T his variation in climatological conditions led to variation in the phonological stages of sweet cherry in two regions under study.

The Effect of Summer Pruning on the Quantity and Quality Production of two Grape Cultivars: Halwani and Balady

This research was carried out to study the effect of summer pruning on the growth and production of two grape varieties Vitis vivifera L. Halwani and Baladdi. The study was conducted in Kadmous during 2012 growing season on two varieties of grape trees reared on wiredraw. Seven treatments were used: 1- control, 2- shoot thinning, 3- shoot thinning and hedging, 4- shoot thinning and axillary shoot removal, 5- shoot thinning and axillary shoot removal, 6- shoot thinning and axillary shoot removal and leaf removal, 7- shoot thinning and leaf removal. Results show that hedging improves weight of cluster and berry due to the increase in fruit set percentage which leads to an increase in grape production. Shoot thinning increases TSS yet other processes have negative effects: the hedging process increases acid titration in the Baladdi cultivar but in the Halwani cultivar hedging and axillary shoot removal increases acid titration.

The effect of apple flower pollination by honeybees on the increase of fruit-set

This study was conducted in the spring of 1999 in Al-Souida Region of Syria, to know the effect of flower pollination by honeybees on flower and fruitset and on the crop productivity of three varieties of apple. The experiment was repeated in the spring of 2001 on the same varieties in addition to others like Yellow sport, but the weather conditions (spring-frost) didn’t allow to obtain results.
