 ABSTRACT

Different characteristics of Pinus roxburghii were recorded from randomly selected 80 trees to establish the relationship between resin yield with diameter at breast height, tree height, bole height, bark thickness, crown width, number of branches, needle length, needle thickness, leaf area index,  transmission coefficient and mean leaf angle. Resin yield was positively and significantly correlated with all tree morphological parameters except number of branches. Quadratic model can be used to predict resin yield with the height.

Keywords: Pinus roxburghii, Correlation, Regression.
