Given below are two statements
Statement (I) : Leaf area index indicates the proportion of ground area covered by leaves
Statement (II) : Relative growth rate indicates the proportionate growth of plant independent of their size
In light of the above statements, choose the most appropriate answer from the options given below.
EXPLANATION
Growth Analysis Parameters, Canopy Architectu
- Statement (I) is True: Leaf Area Index (LAI) is a dimensionless ratio defined by Watson (1947) as the total one-sided green leaf area per unit ground surface area ($\text{LAI} = \text{Leaf Area} / \text{Ground Area}$).
- Statement (II) is True: Relative Growth Rate (RGR) quantifies plant growth efficiency normalized to initial dry weight ($\text{RGR} = \frac{1}{W} \frac{dW}{dt}$), measuring growth vigor independently of baseline plant size.
- Conclusion: Both Statement (I) and Statement (II) are true.
Correct option: (1) Both Statement (I) and Statement (II) are true.
