Spraying the plant surfaces with silicon emulsion and phenyl mercuric acetate results in

A

increases the rate of guttation

B

increases the rate of water absorption

C

decreases the rate of transpiration

D

increases the rate of transpiration

Text Solution

Verified by Experts

The correct Answer is:
C
PMA covers stomata as a film and allows `CO_2` diffusion but restrict diffusion of water and thus reduce transpiration without affecting `CO_2` uptake . Other anti transpirants is ABA
