Question:
The ratio of the weight of water consumed from various sources by a plant in order to produce one unit weight of plant above the root zone is called
The ratio of the weight of water consumed from various sources by a plant in order to produce one unit weight of plant above the root zone is called
Show Hint
\[
\boxed{
\text{Transpiration Ratio}
=
\frac{\text{Water consumed}}{\text{Dry plant matter produced}}
}
\]
A lower transpiration ratio indicates more efficient water utilization by the plant.

Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Recall the definition of transpiration ratio.
The transpiration ratio is defined as the ratio of the weight of water absorbed and transpired by a plant to the dry weight of plant matter produced above the root zone.
Step 2: Identify the correct term. Thus, \[ \boxed{ \text{Transpiration Ratio} = \frac{\text{Weight of water consumed}}{\text{Weight of plant produced}} } \] Hence, \[ \boxed{(D)} \] is the correct answer.
Step 2: Identify the correct term. Thus, \[ \boxed{ \text{Transpiration Ratio} = \frac{\text{Weight of water consumed}}{\text{Weight of plant produced}} } \] Hence, \[ \boxed{(D)} \] is the correct answer.
