Variability in wood chemical composition with age, locality and sampling position of Eucalyptus camaldulensis wood grown at Khipro and Chichawatni were studied. No variation in chemical composition could be found with respect to position of sample in the tree. However, variation among the individual trees is larger than that within a tree. Minor variation in chemical composition of Eucalyptus wood were also noted due to age of trees and locality of their growth.
