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 (GA₃; 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 (° 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 GA₃. Maximum fruit firmness, total soluble solids (° Brix), fruit juice pH, ascorbic acid with minimum titratable acidity (%) were recorded in plants sprayed with 60 ppm GA₃. Boron (100 ppm) and GA₃ (60 ppm) could be applied at the fruit set stage to obtain the quality fruit production of pear.

叶面施用微量营养素和植物生长调节剂（PGR）是直接通过叶片喂食植物的策略之一，无论土壤条件如何，均可快速摄取。这是增强养分平衡及其在农作物中积累的最佳方法，从而可以提高农作物的产量和质量。这项研究研究了硼（0、25、50、75和100 ppm）和赤霉素（GA ₃; 0、20、40和60 ppm）。喷洒75 ppm硼的水果显着提高了水果的重量，单产（kg /棵），最小落果率（％）和疾病发生率（％），而果实硬度（kg / cm），总可溶性固形物（白利糖度），水果喷有100 ppm硼的梨果实的果汁汁pH，抗坏血酸含量和最低可滴定酸度（％）显着增加。在喷有100 ppm的硼和60 ppm的GA _3的梨果实中，酚，类黄酮和抗氧化剂的含量最高（％）。在喷有60 ppm GA _3的植物中，记录到最大的水果硬度，总可溶性固形物（°Brix），果汁pH值，可滴定酸度最低的抗坏血酸（％）。硼（100 ppm）和GA ₃ （60 ppm）可以在坐果阶段使用，以获得梨的优质果实产量。
