Which of the following is a component of the Net Assimilation Rate (NAR) equation?

Relative Growth Rate (RGR)
Leaf Area Ratio (LAR) (correct)
Leaf Area Index (LAI)
Specific Leaf Weight (SLW)

What is the relationship between Leaf Area Ratio (LAR) and its components, Specific Leaf Area (SLA) and Leaf Weight Ratio (LWR)?

LAR = LWR / SLA
LAR = SLA * LWR (correct)
LAR = SLA / LWR
LAR = SLA + LWR

Specific Leaf Area (SLA) (correct)
Net Assimilation Rate (NAR)
Leaf Area Index (LAI)
Specific Leaf Weight (SLW)
