Interrelationship of Wood Yield Components in Eucalyptus tereticornis

Biometrical studies were made in a plantation of Eucalyptus tereticornis in 1976 on seven tree traits namely, total height, merchantable height, girth at breast height, girth at stump level, bark thickness at stump level, weight of green billets after debarking and weight of green bark. Statistical evaluation involving correlation coefficients and path coefficient analysis has Ijrought out the individual influence of the tree traits on the biomass production. The girth at breast height can be taken as a selection index in Eucalyptus tree breeding.
