1.The HPHR has more vascular bundles and a much bigger area of single vascular bundle, total vascular bundle, total phloem and total xylem in the first internode than Shanyou 63.
结果表明,重穗型组合的大维管束数目、单个维管束面积及维管束总面积、韧皮部总面积均明显高于汕优63。
2.Bundle sheath The ring of parenchymatous or sclerenchymatous tissue, usually one cell thick, that surrounds the vascular bundle in an angiosperm leaf.
维管束鞘:在被子植物叶中,围绕维管束的通常是一层薄壁或厚壁细胞。
3.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。
4.There were 495 species,227 genera, and 82 families of vascular plants, including 123 species of arbor, 100 species,of shrubs, 240 species of herbs and 32 species,of strata plants and 15 families 19 genera 19 species of non-vascular bundle plants inchuding 13 species 13 genera 9 familiesof mass and pteridophyte 6 species, 6 genera and 6 families of pteridophyte in the community of Mt.Qingling.
在秦岭林区的锐齿栎群落中出现的维管束植物有 82科 2 2 7属 4 95种 ,其中乔木 12 3种 ,灌木 10 0种 ,草本 2 4 0种 ,层间植物 32种 ; 非维管束植物有 15科 19属 19种 ,其中苔藓植物9科 13属 13种 ,蕨类植物 6科 6属 6种。
5.The stems and rhizomes were observed to differ in cortex-cell layer, perivascular fiber-ring presence, vascular cylinder and pith proportions, vascular bundle number and secondary growth and these differences were associated with their own physiological functions.
地上茎和根状茎之间在皮层细胞层数、周维纤维柱的有无、维管柱和髓所占比例、维管束束数、次生生长等方面存在差异,这些差异与它们各自担负的生理功能相关联。

8.In order to study the reason of the short husk variety in the process of maize inbred lines from microscopic perspective, the vascular bundle characteristic in the cob and the husk were measured by using different varieties of the maize, including the short husk variety of 139 and the contrast variety of No.
为了从微观角度探讨玉米优良自交系选育中出现短苞叶品种的原因,研究了短苞叶自交系139号与1号的雌穗轴和苞叶的维管束特性。
9.With the different development degree of the stem, the distributions of anthraquinone compounds showed different characteristics in the epidermis, cortex, vascular bundle and pith rays.
[结论]蒽醌类化合物在茎中的分布是多位点的,随着茎发育程度的不同,其表皮、皮层、维管束和位射线中蒽醌类化合物的分布表现出不同的特点。
