OBJECTIVE FORESTRY

Detailed explanation-1: -Fruit and leaf drop at early stages can be prevented by the application of the plant hormone or plant growth regulator (PGR) Auxin (Indole-3-acetic acid or IAA). They also promote abscission of mature and older leaves.

Detailed explanation-2: -Auxin delays abscission of young leaves and fruits. Its effect is through nonformation of abscission zone below a leaf or fruit. Abscission zone cuts off nutrients and water supply. However, auxin promotes the abscission of mature or older leaves and fruits.

Detailed explanation-3: -Auxins are plant hormones, generated mostly by roots and stem tips. It aids in the prevention of early leaf and fruit drops.

Detailed explanation-4: -Auxins is a plant hormone that is known to inhibit both premature leaf and fruit fall.

Detailed explanation-5: -Spraying with Auxins can help to prevent leaf fall and fruit drop in a plant. This is because Auxins prevent the formation of a abscission layer which is formed before seperation of plant parts.
