ABSTRACT
Annual ring width and basic density was studied in about 100 samples of Deodar wood to observe variations in both of the parameters and determine the influence of growth rate on density of wood. Results showed that in Deodar wood, the annual ring width ranged from 0.213-5.45mm and the basic density varied from 0.350-0.593gm/cm3. Majority of the studied wood samples were found to have 1- 2mm average annual ring width and 0.401-0.450gm/cm3 basic density of the wood. No specific trend of increase or decrease in basic density of wood with respect to growth rate was observed. The wood samples having lower growth rate had considerable variation in the value of basic density. Similarly the wood samples with higher growth rate were also found to have significant variation in the value of basic density of wood. Further, the wood samples possessing maximum and the minimum growth rate, both had an intermediate value of basic density of wood. Likewise, the wood samples possessing the highest and lowest value of basic density, both were found to have a medium value of average annual ring width.
