Estimation of biomass in Hevea clones by regression method: 2. Relation of girth and biomass for mature trees of clone RRIM 600
Material type:
TextPublication details: Indian Journal of Natural Rubber Research 1996Description: 40-43Subject(s): Summary: Determination of biomass in tree crops like Hevea is cumbersome and a most viable alternative method is estimate the biomass as a function of a common measure of growth, like girth. In the present study relationships were worked out with girth at 150 cm from bud union and above ground biomass for trees of clone RRIM 600. Both power as well as exponential regression equations fitted were found to be reliable in all classes of girth from 45 to 93 cm. The relationships are W = 0.0202 G2.249 (power) and W = 24.8486 e0.0343G(exponential).
