- R ays e ntirely p arenchymatous , u ni - serate ; h orizontal a nd t angential w alls o f r ay c ells a re smooth and thin
木射线单列全由射线薄壁细胞组成；射线细胞水平壁薄；端壁薄，平滑。 - Rays entirely parenchymatous , uni - serate ; horizontal and tangential walls of ray cells smooth and thin . cross - field pitting taxodoid with 1 - 4 pits
木射线单列，全由射线薄壁细胞组成；射线细胞水平壁薄，纹孔缺乏，端壁平滑。 - The tissue - localization showed that there were more silver - grains labelled in the ray , callus and regenerated differentiating vascular tissue cells than that in other tissues . it further suggested that the high concentration of endogenous iaa triggered the dedifferentiation of the immature vascular tissues after girdling , and the lower concentrated iaa flow could promote the initiation and activity of the regenerated cambium
内源iaa组织定位的结果表明射线细胞愈伤组织和新生维管组织内均有较多的银颗粒标记。这些似可表明，高浓度的内源iaa可启动未成熟维管组织细胞的脱分化，而较低浓度的内源iaa流则可诱导再生形成层的发生和活动。 - More anthraquinone compounds was distributed in pith ray cells and the tissues of mature stem suchas bundle sheaths in large - scale vascular bundle , primary phloem and primary xylem than that in young stem . [ conclusion ] the distribution of anthraquinone compounds in the stem was of multilocus
结果随着茎的不断成熟，在茎的表皮、近表皮的1 ~ 2层皮层细胞及较内部皮层中，不同程度地增加贮藏和积累了一定数量的蒽醌类化合物，成为茎外部贮藏和积累蒽醌共化合物的主要结构部位成热茎大型维管束的维管束鞘、初生韧皮部、初生木质部等组织和髓射线细胞分布了比幼茎多的蒽醌类化合物。
