Abstract

The investigations were carried out to study the effect of morphological and environmental parameters on oleoresin yield. The experiment was carried out in Jelly UPF –167, Unprotected Forest of Mashobra Range of Shimla Forest Division of Himachal Pradesh. Borehole method of tapping was used to extract the oleoresin from Pinus wallichiana. The trees having the diameter of 30-35 cm were selected for tapping. Highly significant and positive simple correlation coefficients and genotypic and phenotypic correlation coefficients were observed between oleoresin yield vs. needle length and oleoresin yield vs. height of trees. The correlation studies between oleoresin yield and environmental factors showed that the oleoresin yield was directly correlated with temperature and negatively correlated with rainfall.
