Natural Decay Resistance of Indian Timbers. VI. Decay Resistance of Sissoo (Dalbergia sissoo Roxb.), and Sandan (Ougeinia oojeinensis (Roxb.) Hochreut)

Results of studies on the natural decay resistance of sissoo and sandan by soil
block method are reported. While sissoo belongs to very resistant class and exhibits
little or no variation in decay resistance of 'outer' and 'inner' heartwood, sandan
manifests large variations in decay resistance amongst different samples, and within
a sample between 'outer' and 'inner' heartwood. These variations in the latter species are not correlated with heartwood diameter, age of tree or difference in rate of growth of heartwood in the 'outer' aud 'inner' regions.

little or no variation in decay resistance of 'outer' and 'inner' heartwood, sandan
manifests large variations in decay resistance amongst different samples, and within
a sample between 'outer' and 'inner' heartwood. These variations in the latter species are not correlated with heartwood diameter, age of tree or difference in rate of growth of heartwood in the 'outer' aud 'inner' regions.
