Question

Abscisic acid called as stress harmon why

Answer 1

Abscisic acid is called stress hormones as it induces various responses in plants against stress conditions.

It increases the tolerance of plants toward various stresses. It induces the closure of the stomata during water stress. It promotes seed dormancy and ensures seed germination during favourable conditions. It helps seeds withstand desiccation. It also helps in inducing dormancy in plants at the end of the growing season and promotes abscission of leaves, fruits, and flowers.

Answer 2

When we are stressed adrenaline is released which makes our body fit for the situation. Similarly in order to adapt in the extreme environmental conditions plants also release Absicic acid which prepares them for that situation like during summers it closes the stomata and during the winters whittling of leaves.
