| Summary: | Carbon is sequestered by plant through photosynthesis and stored as biomass in different parts of the tree including stems,
branches, leaves and roots. The objective of this study is to determine the biomass in five different growth stages of rubber
tree saplings and to develop the allometric equation for biomass estimation. Biomass of rubber tree saplings was measured
for the growth stages of 45, 90, 135, 180 and 225 days with total number of samples used was 650 saplings. Biomass was
determined by weighing the constant dry weight of the samples. Four candidate models were selected and evaluated and
Model 4 appeared to be the best allometric equations for biomass estimation of rubber tree saplings in the form of log10
W = 0.184 + 0.007 log10 D + 0.705 log10 HT + 0.002 log10 AG, (R2=0.96). The allometric equation developed in this study is
useful for the estimations of biomass in rubber tree saplings. |
