| description | <p id="p1">One of the main factors for the abscission of flowers/fruits is lack of pollination (fertilization); however, numerous other factors contribute to low effective fruitings, such as environment, genetics, and orchard management. Some cultivars are more likely to have a low fruit set than others, especially when an adverse factor occurs. The spraying of growth regulators in flowering stages can increase the effective fruiting in adverse conditions. A treatment with a low dose of growth regulators can improve fruit set. After bloom, an initial increase in fruit set can be observed after treatment with Thiadizuron (TDZ), Proexadiona calcica (Pca), and Aminoetoxyvinylglycine (AVG). TDZ combined with PCa + AVG increases the fruit set of “Monalisa” apple trees and does not cause alternate bearing, however, it reduces the average fruit mass.</p> |
