Estimation of lignin content in some coniferous wood of western Himalayas

The present studies were conducted to estimate the variation in lignin content of some coniferous wood from different sites of Himachal Pradesh. The data on lignin content of wood exhibited significant variation in different species from variable sites. The highest value of 28.50 per cent was recorded in S₁ (Pinus roxburghii) and lowest 25.92 per cent in S₄ (Cedrus deodara). Among the sites maximum value of 28.69 per cent was observed in L₁ (Chamba) and minimum 25.42 per cent in L₃(Solan). The interactions between species and sites were also found to be significant. The maximum value of 30.68 per cent was found in wood of P roxburghii (S₁) at Chamba (L₁) while minimumof 23.63 per cent was recorded in C deodara (S₄) woodat L₃ (Solan). The results wouldhelpto utilize the findings and developing future strategies for screening of coniferous wood for utilization.
