| dc.description.abstract | Variation in wood physical (specific gravity) anatomical (vessel and ray morphology) and chemical (cellulose and lignin per cent ) properties of 46 casuarina (casuarina equisetifolia L) clones grown in Karur district, Tamil Nadu was studied to assess their suitability for pulp and paper making. Transverse dics collected from billets were converted to smaller specimens for undertaking studies on wood physical, chemical and anatomical properties. Estimation of specific gravity was undertaken using a precision balance and fibre morphology was studied using an image analysis system. Cellulose and lignin were estimated using standard procedures. Nested analysis of variance was carried out to find out inter and intra clonal variation of clones. All the physical and anatomical properties except fibre lumen width, runkel ratio, rigidity coefficient , flexibility coefficient and shape factor, showed significant difference between clones. Within clone variation was also significant for all the physical and anatomical parameters except specific gravity (oven dry). In order to assess the suitability of clones for pulp and paper making, specific gravity (oven dry), fibre length, Runkel ratio, shape factor, slenderness ratio, flexibility coefficient , rigidity coefficient , and cellulose and lignin content of clones were found to be within the acceptable range for pulp and paper making , clones were grouped to four clusters by carrying out hierarchical cluster analysis on the basis of all physical, anatomical, chemical and growth parameters. Cluster 4 (one clone) and cluster 2 (11 clones) were found to be better for pulp and paper making in comparison to other clusters. | en_US |
