Abstract

In this research microscopic properties of wood near the pith to bark in Dalbergia sissoo was investigated. For this reason 3 stands of 10 years old Dalbergia sissoo trees from ShoshDanial area in Khozestan province were selected and cut. For measuring fiber biometrics of samples, from each trees one disc and from each disc 10 pell in match's size segregated and tested. Segregation of fibers was done with Franklin method. Also microscopic segments of wood near the pith and bark were studied with light microscope. The results showed that the length, total and lumen diameter, and thickness of cell wall are significantly different and this values were increased from pith to bark. Ray widths and vessel diameters in wood near the pith and bark were 36.15, 132.98 and 31.82, 98.26 µm respectively and showed a significant difference in the level of 5%. The average number of vessels and the number of rays in wood near the pith and bark were 3.46, 7.20 and 3.54, 6.68 number respectively. Also ray length means in wood near the pith and bark were 130.86 and 132.05µm respectively and didn’t show a significant difference in the level of 5%.
