This is the tenth video of the plant growth and development series.

The video explains the following aspects-
1.The discovery of Abscisin II, Dormin and their naming as Abscisic acid.
2.The source of ABA in plants.
3.functions of Abscisic acid-
Promotes senescence
-Promotes abscission by formation of abscission zone.
-Supports Bud and seed dormancy
Acts as stress hormone- closure of stomata: Mechanism
-Antagonistic in function to gibberellins.
