摘要: <正>本文研究了马尾松枝桠材的应压木、对应木与正常干材的解剖特征,比较了三者在生长轮宽度、晚材率、早晚材过渡形式、管胞形状,胞间隙、螺纹裂隙等方面的异同,发现它们在管胞长度、管胞直径及细胞壁厚度、细胞壁超微结构以及次生壁S_2层微纤丝角度诸方面存在差异。

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.
