| 7. | The results showed that there are no significant difference within the stomatic distribution of outer epidermis of young and aged stem and aged leaf sheath in three plants ; but there are significant or very significant difference within apex , middle and base of young and aged leaves
结果表明：三种植物的幼茎、成熟茎和成熟叶鞘外表皮的上部、中部、基部的气孔分布均无显著性差异，而幼叶和成熟叶的上、中、下部的气孔分布存在着显著性差异或极显著差异。 |
| 8. | The results showed that there are no significant difference organs , within the stomatic distribution of outer epidermis of young and aged stem and aged lea , sheath in three plants ; but there are significant or very significant difference within apex , middle and base of young and aged leaves
结果表明：三种植物的幼茎、成熟茎和成熟叶鞘外表皮的上部、中部、基部的气孔分布均无显著性差异，而幼叶和成熟叶的上、中、下部的气孔分布存在著显著性差异或极显著差异。 |
| 9. | 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。 |
