SUITABILITY OF CASUARINA EQUISETIFOLIA WOOD FOR PULP AND PAPER INDUSTRY IN PAKISTAN A MAHMOOD Abstract: Wood chemical constituents such as holocellulose, alphacellulose and lignin contents of Casuarina cqllisclifolia were investigated from extractive - free wood of trunks and branches. In trunk wood amount of holocellulose, alphacellulose and lignin wee 73.08±3.91, 46.41 ±4.49 and 26.32±3.71% respectively, whereas for branch wood the corresponding values were 72.14±: 2.20, 42.87± 2.66 and 27.73± 1.55% respectively. The average fiber length, fiber diameter and fiber wall thickness was 978.28±48.26 mm, 14.81±4.97 µ.m and 6.95±t2.86 µ.m respectively. The amount of holocellulose, alphacellulose and lignin in the trunk wood and branch wood when compared with other types of wood suggest that relatively high pulp yield can be obtained r rom them. However, short lengt h and small diameter of fibers would render Casuarina wood unsuitable for making strong paper. Department of Botany, University of Karachi, Karachi-75270, Pakistan. |
