Q44
Which of the following relation is true,
A.
RGR = NAR × LAI
AnswerB.
RGR = NAR × LAR
C.
LAI = CGR × RGR
D.
None of the above
Answer: Option A
Solution
Answer: Option A
Solution:
RGR is the Relative Growth Rate.NAR is the Net assimilation Rate.
LAI is the Leaf area Index.
Thus, the relative growth rate depends on both the net assimilation rate as well as leaf area index. Light falling on the leaf and absorbed depends on the availability per unit area further influencing the rate of photosynthesis and assimilation ultimately the growth rate of the plant.
