| Abstract: | This paper deals with the anatomical aspects of compression wood and opposite wood of branches and normal stemwood of Pinus massoniana. The results show that there are differences a-mong these three tissues in growth ring width and latewood proportion in tracheid shape of cross section and dimension in earlywood and latewood, in intercelluar spaces, in type and dimension of rays, in layer's structures of tracheidwall and helical cavities and in S2 layer's microfibril angles. |
