Abstract
This experiment was carried out during 2014 and 2015 seasons on 'Canino' apricot trees grown in sandy soil under drip irrigation system in a private farm at El-Bostan region in Behera governorate, Egypt to study the effect of foliar spraying with Yeast (0.1 and 0.2%), Benzyladenine (50 and 100 ppm), GA3 (50 and 100 ppm), Boric acid (25 and 50 ppm) and flower power (2 and 4%) at full bloom stage on fruit set and fruit quality. Results showed that spraying 'Canino' trees with BA at 100 ppm followed by Boric acid (25 ppm) as well as GA3 (50 ppm) gave the highest significant fruit set in comparison to control. Fruit weight, volume, length, width and fruit flush weight were significantly increased as result of GA3 at 50 ppm, Flower power (4%) and GA3 (100 ppm) treatments respectively. Moreover, firmness of fruits obtained from BA at 50 ppm and Flower power at 4% treatments were significantly higher than control. The data also reveal that applied treatments had no significant effect on fruit shape index (L/W). Concerning the results of fruit kernel properties, it was noticed that, GA3 at 50 ppm, boric acid (25 ppm) and flower power (2%) treatments were more effective to enhance 'Canion' kernel properties. Treatments of BA at 100 ppm and Yeast at 0.1 % as well as Flower power at 4% increased SSC (%) and SSC/acid ratio. However, all treatments significantly decreased acidity percentage comparing with control fruits. It can be concluded that, most of the studied parameters were enhanced with foliar applications of GA3 at 50 ppm, BA at 100 ppm and Flower power at 4% at full bloom stage of 'Canino' apricot trees in comparison with control treatment.
