Indian Forest Utilization

1913

Heartwood is formed by the deposition of colouring maters and other substances in the cells or on the walls of the cells and other tissues of the wood whereby the walls get thicker and lignified and the wood thus becomes denser and heavier. [...] The chief factors which influence the shape and dimensions of trees as well as the proportion of stem-wood branch-wood and root-wood are (1) the species (2) the density of the crop (3) the age of the tree (4) the soil and locality (5) the sylvicutural system adopted. [...] The specific gravity of a wood depends mainly on the quantity of woody substance in its tissues that is the thicker the cell-walls and the smaller the lumina the higher the specific gravity of the wood. [...] On the other hand the formation of heavy heartwood during middle age may render the average specific gravity of the wood of old trees considerably higher than that of young trees : hence no definite rule can be laid down as to the effect of the age of a tree on the specific gravity of the wood particularly in the case of trees which form a distinct heartwood. [...] Thus in conifers the narrow16 ringed resinous wood of the branches is heavier and harder than the wood of the stem while the wood at the base of the tree and in the larger roots being highly impregnated with resin is considerably heavier than the stem-wood.
