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) |
\(SLA=\frac{\text{Leaf\ area}}{\text{Leaf\ dry\ weight}}\) |
