Note on the Effect of Frequent Freshenings on Resin Yield from <I>Chil (Pinus roxburghii)</I>

Abstract

Results of an experiment conducted to study the effect of three frequencies of freshening on resin yield from blazes paired on individual tree are summarized. Three freshenings a week increased resin yield significantly over two freshenings a week which in turn gave significantly higher resin yield than one freshening a week. Resin yield per blaze per freshening decreased with increased frequency of freshening.
