Abstract
This study carried out during 2013 and 2014 seasons to study the effect of foliar application of GA3 (at 15 and 30 ppm) and B12 (at 2 and 4 mg L-1), and the combinations between them. The study aims to improve fruit quality of "Le-Conte "pear trees. Materials were applied at 30% of bloom, 70% of bloom and after fruit set. Measurements included: vegetative growth, leaf area, leaf chemical content, fruit yield and quality. Mentioned components, responded positively to the studied treatments. The application at high concentration GA3 30 ppm plus B12 4 mg L-1 is recommended to improve productivity which increased grower income. Generally, this study achieved main target for fruit producers, high yield, quality which led to increased grower income.
