How can plants be grown under limited water supply without compromising on metabolic activities?

Question

Philoid · Accepted Answer

Plants can be grown under limited water supply without compromising on metabolic activities by a number of ways:

Plants usually shrink when the rate of transpiration exceeds the rate of absorption of water by roots. So if we use anti-transpirants like Abscisic acid then it checks the rate of transpiration. This would reduce loss of water by plants but the metabolic activities shall go on along with diffusion of gases.
