Variation in soluble extractives, lignin and holocellose content of wood of high resin yielders and check trees in Chirpine (Pinus Roxburghii Sargent)

The present studies were conducted on variation in soluble extractives, lignin and holocellose content of wood of high resin yielders (HRYs) and check trees in Chir pine (Pinus roxburghii). The data on cold and hot water solubility, alcohol-benzene solubility, lignin content and holocellulose content of wood exhibited significant variation in different high resin yielders and check trees in Chir pine. Among different marked trees, the highest cold water solubility and hot water solubility was noticed in Jhojonbailly-check. UHF-4 HRY recorded maximum percentage of alcohol-benzene solubility. Lowest cold and hot water solubility was obtained for Ghandir-1 and minimum per cent of alcohol-benzene solubility was recorded in Sarkaghat check. Maximum percentage of lignin and holocellulose content was observed in Bumbloo-check and UHF-4 HRY, respectively. Whereas, minimum percentage of lignin and holocellulose was found in Hareta Road-6 and Platu-2 HRY, respectively.
