Description ABSTRACT
The present study entitled “Stability analysis of resin yield of natural regenerated Pinus
roxburghii Sargent” was undertaken in the Department of Basic Science, Dr. Y.S. Parmar University
of Horticulture and Forestry, Nauni, Solan 173230 (H.P.) during 2012-2013. Secondary data on
resin yield for 145 trees for seven years from 2005-2011 were taken and the data were subjected
to the stability analysis. Wricke model (1962), Finlay and Wilkinson’s (1963) and Eberhart and
Russell’s (1966) were used to identify stable diameter class. Diameter classes 35-40 cm and 40-45 cm
were found to be most stable diameter classes by using all stability models. 145 trees were divided
into seven diameter classes. Lognormal and gamma probability distributions were tried to find out
the number of trees in each diameter class and both distributions were statistically fitted with
observed diameter distribution, however resin yield showed behavior of lognormal
distribution.
