Mango Glossary

An abscission layer is a specialized zone of cells where a plant part can separate from the plant. In mango fruit drop, changes at the fruit attachment allow flowers or fruitlets to detach as part of normal development or in response to stress. Some early drop is expected because the tree cannot mature every flower into fruit. Excessive losses need context: crop stage, pollination, disease, water supply, and weather may all matter. The existence of an abscission zone does not identify a single cause of drop.
