Question:
RGR is equal to:
RGR is equal to:
Show Hint
RGR = NAR \(\times\) LAR.
NAR: photosynthetic efficiency.
LAR: leaf area efficiency.
NAR: photosynthetic efficiency.
LAR: leaf area efficiency.
Updated On: Aug 18, 2026
- NAR LAR
- NAR + LAR
- (NAR + LAR) NAR
- NAR \(\times\) LAR
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
RGR (Relative Growth Rate) is a growth parameter.
It is related to other growth parameters.
Step 2: Key Formula or Approach:
RGR = NAR \(\times\) LAR.
Where NAR is Net Assimilation Rate and LAR is Leaf Area Ratio.
Step 3: Detailed Explanation:
Relative Growth Rate (RGR) is the product of NAR and LAR.
NAR is the increase in dry weight per unit leaf area per unit time.
LAR is the leaf area per unit total plant weight.
Thus, RGR = NAR \(\times\) LAR.
Step 4: Final Answer:
RGR is equal to NAR \(\times\) LAR.
Hence, the correct option is (D).
