Question

Abscisic acid prevents transpiration.? How it happens? ​

Answer 1

Explanation:

When acetic acid is tretead then the temperature of leaf increases and accumulation of absasic acid decreased the conduction of stomata and further decreasing the rate of transpiration .

Answer 2

Answer:  The ABA-induced stomatal closure reduces transpiration (evaporation of water out of the stomata), thus preventing further water loss from the leaves in times of low water availability.
