Q591

Physiological Wilt is associated with which stress?

A.
Osmotic stress
Answer
B.
Chilling stress
C.
Nutritional stress
D.
Abiotic stress

Answer: Option A

Solution

Answer: Option A
Solution:
Physiological Wilt is associated with Osmotic stress.
Wilting of the plants when caused by drought or waterlogged soil is considered physiological wilting.
Osmotic stress leads to efflux or influx of water from or into the cell. It is triggered by water and electrolyte imbalance typically caused by dehydration.
Hyperosmotic stress causes shrinking and hypoosmotic stress causes swelling and ultimately damages the cells of the plants.
