Abstract:
The Yield of fruit tree crops are determined with the aid of using flowering efficiency and successive fruit set from the ones flowers. Many factors of the abscission manner were reviewed with inside the past but in this review, we discussed the causes and control of flower drop in fruit trees. Abscission has been defined as the natural process of detachment of parts of a plant from the main body of the plant. In other words, we can say that it is a natural feature or characteristics of plant development which incorporates the loss of fruit, leaves, sepals, stamens, petals, style and flowers. Numerous studies have shown that the various causes of fruit drop that highlights the high Abscisic acid (ABA) content and low Indole-3-acetic acid (IAA) and low deliver of photosynthate and improper Nitrogen application, improper fertilization, Auxin deficiency, heavy crop load. The reduction of this problem has been successfully controlled through the application of some plant growth hormones including GA3 with Zn and ethylene and 1-MCP. The research revealed from the findings that the major reasons of flower detachment is related to ethylene production in a specific amount. And also, the status of the leaf NPK is not the main concern of flower drooping/ drop.
