Question

Which hormone does stop premature leaf fall?

Answer 1

Auxins:

1. Auxins is a plant hormone that is known to inhibit both premature leaf and fruit fall.
2. Auxin postpones the abscission of young leaves and fruits. It has an effect by inhibiting the formation of an abscission zone beneath a leaf or fruit.
3. The abscission zone means cutting off the source of nutrients and water.
4. Auxin, on the other hand, helps promote the abscission of fully grown or older leaves and fruits.
