Phytohormone connected with closing of stomata is
Open in App
Solution
The correct option is A ABA
Abscisic acid is an antitranspirant and induces seed dormancy. It helps in the closure of stomata which reduces transpiration. It curtails the stress in plants by inducing stomatal closure. When the rate of transpiration increases more than that of the available water, the plant undergoes stress and in order to prevent the plant from wilting the ABA acts as antitranspirant and closes the stomata. It induces seed dormancy so it is also known as dormin. It was first discovered by Adicott in cotton balls. It reduces the cambial activity and also accelerates the abscission and senescence.So, the correct answer is option A.
