Traits (Abbreviation) Equation Units Note
Relative growth rate of total dry weight (RGRB) \(\text{RGR}_{B}=\frac{(ln\text{BM}_{f}-ln\text{BM}_{i})}{t}\) g/day BM and Sl represent total dry weight and stem length respectively. t means total time for experiment, f and i represented final and initial values respectively.
Relative growth rate of stem length (RGRSl) \(\text{RGR}_{\text{Sl}}=\frac{(ln\text{Sl}_{f}-ln\text{Sl}_{i})}{t}\) cm/day
Stem weight ratio (SWR) \(SWR=\frac{\text{Total\ stem\ weight}}{\text{total\ weight}}\) g/g
Root weight ratio (RWR) \(RWR=\frac{\text{Total\ root\ weight}}{\text{total\ weight}}\) g/g
Specific leaf area (SLA) \(SLA=\frac{\text{Leaf\ area}}{\text{Leaf\ dry\ weight}}\) mm2/mg
