Q434

In stress condition, Leaf water potential

A.
Increases
B.
Decreases
Answer
C.
Increase than decrease
D.
All of the above

Answer: Option B

Solution

Answer: Option B
Solution:
Leaf water potential (LWP) is a useful index of soil water stress when experienced by plants.
When plants undergo water stress, under low availability of water, plants develop mechanisms to cope with water stress by decreasing LWP.
Air temperature, humidity, wind and soil water availability are the factors that affect LWP.
