Question

What are growth-regulators ? Mention growth regulators and describe growth-regulator containing Indole.

Answer 1

Plant growth regulators (also known as phytohormones) are signal moleculesproduced within plants, that occur in extremely low concentrations. They exert strong control over plant development and can either act locally or in more distant part of the plant.

The five main plant hormones are
auxins
 gibberellins
 cytokinins
 abscisic acid (ABA) and
 ethylene. 


indole-3-acetic acid (IAA) is the most abundant and the basic auxin natively occurring and functioning in plants. It generates the majority of auxin effects in intact plants, and is the most potent native auxin.
