WebOct 2, 2024 · using the formula suggested by Watson (1947) and expressed in days. LAD = L i + (L i +1) x ( t 2 – t 1) 2 L i = LAI at first stage; L +1 = LAI at second stage (t 2 – t 1) = time interval between stages in days Specific leaf weight (SLW) was calculated by using the formula suggested by Pearce et al., (1968) and expressed in g m-2. WebJan 1, 1985 · Specific leaf area and leaf weight ratio. Leaf area ratio can be redefined as: (2.10) F= W 1 W × s W 1 where W l is the dry weight of the leaves. The two components W l /W and s/W l are called the leaf weight ratio (LWR) and the specific leaf area (SLA) respectively. LWR defines leaf area ratio in terms of leaf density (i.e. kg.kg −1), ... paissa threadpuller
