木薄壁组织

软枣猕猴桃木薄壁组织及木射线的研究

Studies on wood parenchyma and wood rays of Actinidia arguta ( sieb et zucc ) Planch ex Miquel

导管具单穿孔板，轴向木薄壁组织丰富，傍管型居多，为翼状傍管薄壁组织和环管薄壁组织；

There are plenty of wood parenchyma in the secondary xylem , most of them are paratracheal parenchyma , belong to the aliform paratracheal parenchyma and vasicentric paratracheal parenchyma ;

轴向系统由管胞和木薄壁组织细胞组成；

Axial and radial systems formed the secondary xylem of the roots .

弦切面上木射线与轴向薄壁组织形状、大小均不相同；

The shape and size of wood ray is different form that of longitudinal parenchyma ;

维管组织中次生韧皮部所占根径的比例达46%，其薄壁细胞中内含物较丰富，次生木质部中分布有导管和木射线及少量木薄壁组织；

The secondary phloem occupied 46 % of the diameter of the root and the parenchymas cells had abundant inclusions . The secondary xylem consisted of vessels , and xylary radial and some xylary parenchyma cells .

木纤维比量、导管比量、木射线比量和薄壁组织比量平均值分别为54.8%、16.5%、27.6%、1.1%；

The average proportion of fiber tissues , proportion of vessel tissues , proportion of wood ray tissues and proportion of longitudinal parenchyma were respectively 54.8 % , 16.5 % , 27.6 % , 1.1 % .
