Question

It's written that ABA hormone inhibits plant growth and metabolism, their days that ABA plays an important role in seed development and maturation. How is that possible?

Answer 1

inhibitors were chemically identical and were, therefore, together were given the name abscisic acid. Abscisic acid mostly acts as an antagonist to Gibberellic acid.

Effects

• Regulate abscission and dormancy.
• Inhibit plant growth, metabolism and seed germination.
• Stimulates closure of stomata in the epidermis.
• It increases the tolerance of plants to different kinds of stress and is, therefore, called ‘stress hormone’.
• Important for seed development and maturation.
• It induces dormancy in seeds and helps them withstand desiccation and other unfavourable growth factors
• Because of function of ABA both maturation and seed development occurs
