• 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.
