Q113
When LAI = 1,
A.
RGR = LAD
B.
NAR = LAR
C.
LAR = LER
D.
CGR = NAR
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
LAI = Leaf Area IndexCGR = Crop Growth Rate
NAR = Net Assimilation Rate
LAR = Leaf Area Ratio
RGR = Relative Growth Rate
When LAI is 1, then Crop growth Rate is the same Net Assimilation Rate. A low leaf area index directly influences the light interception per unit area, affecting CGR and ultimately the NAR.
