Özet

Foliar application of micronutrients and plant growth regulators (PGRs) is one of the strategies of plant-feeding direct through leaves to allow rapid uptake irrespective of soil condition. This is the best way to enhance nutrient balance and its accumulation in the crops that, in turn, lead to improved crop yield and quality. This research studied the effect of boron (0, 25, 50, 75, and 100 ppm) and gibberellic acid (GA(3); 0, 20, 40, and 60 ppm) on quality fruit production of pear. Fruit weight, yield (kg/tree), minimum fruit drop (%) and disease incidence (%) were significantly enhanced in fruit sprayed with 75 ppm boron while fruit firmness (kg/cm), total soluble solids (degrees Brix), fruit juice pH, ascorbic acid content, and minimum titratable acidity (%) significantly increased in pear fruit sprayed with 100 ppm boron. The highest contents of phenols, flavonoids, and antioxidants (%) were observed in pear fruit sprayed with 100 ppm of boron and 60 ppm of GA(3). Maximum fruit firmness, total soluble solids (degrees Brix), fruit juice pH, ascorbic acid with minimum titratable acidity (%) were recorded in plants sprayed with 60 ppm GA(3). Boron (100 ppm) and GA(3) (60 ppm) could be applied at the fruit set stage to obtain the quality fruit production of pear.
