Correlation and regression analysis of wood properties of Dalbergia sissoo Roxb. ex DC. Procured from local markets of Himachal Pradesh, India

Abstract

The relationships between different wood properties were being carried out to check the dependence of one character over the other which defines the overall quality and performance of the wood which is being subjected to utilization. The correlation was found positive and highly significant for specific gravity with fibre diameter, bending strength with modulus of rupture, tensile strength with tension modulus of elasticity. The correlation was observed negative for tensile strength with fibre length, tension modulus of elasticity with vessel diameter and fibre length, bending modulus of elasticity with modulus of elasticity compression parallel to grain followed by modulus of rupture with vessel diameter. Coefficient of determination (R2) was observed to be more than 0.70 for specific gravity (0.883) and tensile modulus of elasticity (0.894) when regressed with other wood parameters.
