Abstract : The present studies were conducted on variation in soluble extractives, lignin and holocellulose content of wood of different provenances of Tectona grandis. The data on cold and hot water solubility, alcohol-benzene solubility, lignin and holocellulose content of wood exhibited significant variation in different provenances of Teak. Among different selected provenances, the highest cold water solubility [16.43% (4.05)] and hot water solubility [19.56% (4.42)] was recorded in APNPL-10 and lowest was recorded in ORPLM-1 [6.34% (2.52)] and [8.34% (2.89)], respectively. Maximum percentage of alcohol-benzene solubility was observed in KLN-2 [17.64% (4.20)] and minimum per cent was recorded in MHSC-J1 [7.13% (2.67)]. Maximum percentage of lignin [39.00 % (38.64)] and holocellulose (76.53%) content was noticed in ORANP-6 and APT-11, respectively. whereas, minimum percentage of lignin 20.83% (27.15) and holocellulose (64.20%) content were found in TNT-10 and APT-20, respectively. The study would help to utilize the findings and developing future strategies for screening the provenances of Tectona grandis.
