Questions and Answers

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

    • Which of the following is a measure of the leaf area per unit of leaf dry weight?

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