Evaluation of holocellulose and lignin content of wood of banoak provenances from Himachal Pradesh

Abstract

Wood is composed of three primary cell wall constituents namely cellulose, hemicellulose and lignin, which interacts in such a way so as to form a natural composite. The present study aimed at evaluating the content of holocellulose and lignin in the wood of banoak (Quercus leucotrichophora) among twenty two provenances from Himachal Pradesh. The average holocellulose content ranged from 65.31 % to 71.30 %. The maximum and minimum holocellulose content was found in Barog (71.30 %) and Banikhet (65.31 %), respectively. The average lignin content was ranged from 20.48 % to 28.46 %. The maximum and minimum lignin content was observed in Dhami (28.46 %) and Jibhi (20.48 %), respectively.
