Question

Which hormone is concerned chiefly with root initiation ?

Answer 1

IAA hormone is concerned chiefly with the root inflation.

Auxin refers to a group of many artificial or natural plant hormones.

Amongst these the most common and physiologically noted is auxin which is an indole acetic acid or IAA.

Many are manufactured, or synthesized.

The later naphthalene acetic acid stimulates root development on stem cuttings.
