What’s main functions of S-Abscisic acid ?

S-Abscisic acid is an inhibiting hormone in plants that helps a plant adapt to stress environment. It also plays a vital role in the closure of the leafs stomata, bud development, and seed dormancy.

In autumn, ABA stimulates the plant to goes dormancy and stop producing new growth in preparation for the next cold winter climate.
