摘要

The present study was conducted to know the percentage of occurrence of twisted trees in some natural high resin yielding stands of Himachal Pradesh. Four forest divisions, viz., Soian, Kunihar, Dharamshala and Hamirpur were selected and four sample plots were randomly laid out in each division. Quantitative measurements were made and locality conditions were recorded in the sample plots. Chi-square test was used to study the association of degree of twist with other tree characters. The test revealed that the degree of twist does not influence any characters of tree, viz., height, dbh, clear bole, crown width, bole shape, needle colour, needle length, number, position and size of resin canals in the needle cross section, tracheid length and degreeof twist in the tracheids.
