The variation in the proportion of heartwood has been studied in 89 years old Eucalyptus tereticornis Sm. trees, raised in four different plantations viz. Haldwani, Shahdol, Bangalore and Coimbatore. The heartwood volume calculated from its propogation in various discs, has been found to be significantly affected by the locality of growth; within a locality it is correlated with the girth at breast height.
