| 1. | Ray width 1 - 3 cells ; body ray cells procumbent with 1 - 9 rows of upright and / or square 木纤维细胞壁中等厚度。射线宽l 3细胞。 |
| 2. | Ray width 1 - 4 cells ; body ray cells procumbent with 1 - 4 rows of upright and / or square marginal cells 射线多列和单列射线组成,两种大小, 14细胞宽。 |
| 3. | Ray width 1 - 4 cells ; body ray cells procumbent with 1 - 9 rows of upright and / or square marginal cells . ericaceoxylon cf 射线宽14细胞;多列射线的中部多为横卧细胞,边缘有l 9行直立和或方形细胞。 |
| 4. | Ray width 1 - 6 cells ; body ray cells procumbent with mostly 2 - 4 rows of upright and / or sqaure marginal cells . ericaceoxylon hymenanthesoides sp 多列射线的中部多为横卧细胞,边缘有1 - 4 ( 6 )行直立和或方形细胞。 |
| 5. | 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。 |
| 6. | The protein accumulated mainly in secondary phloem parenchyma cells and secondary phloem ray cells . the degradation of storage protein in terminal branchlets of swietenia macrophylla synchronized with new shoot growth after leaf - absent period , suggesting that the protein was utilized to support the growth of new shoots . when the diminishing of the storage protein below the girdled site was blocked , the new shoot growth was also restrained 在树木新的年生长周期中,随着新梢的发育,积累在末端小枝中的贮藏蛋白质开始被消耗新梢叶片成熟时,末端小枝中的18kda和21kda蛋白质己完全消失,而树干和大根中的这两种蛋白质的含量相对稳定,与落叶期相比几乎没有变化。 |
| 7. | 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。 |
