Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Wilting coefficient is the soil moisture content at which plants can no longer extract water.
Step 2: Detailed Explanation:
Wilting coefficient (also called permanent wilting point) is:
- The lower level of plant available water (C).
At this point, plants wilt permanently and cannot recover.
It represents the lower limit of available water for plants.
Other terms:
- Upper level of super available water (A): Not a standard term.
- Upper level of plant available water (B): Field capacity.
- Lower level of capillary water (D): Not a standard term.
- Upper level of field capacity (E): Field capacity.
Thus, the wilting coefficient signifies the lower level of plant available water.
Step 3: Final Answer:
Thus, the wilting coefficient signifies the lower level of plant available water.
[0.5cm]
