Leaf dry weight of the fully hydrated leaves from the middle of stem (mg)
Natural logarithm plus 3
SLA
Specific leaf area is area/dry weight (mm2/mg)
Square root
PN
Photosynthetic capacity (mg CO2/g dry weight per hour)
Square root
RD
Respiration rate in dark (mg CO2/g dry weight per hour)
Square root
LNC
Leaf nitrogen concentration (mg/g)
Square root
LCC
Leaf carbon concentration (mg/g)
Square root
et al. [11] used a point system to assess height. However, we used continuous transformation of natural logarithm in order to reduce the information losses.
