辣椒叶柄解剖结构数量特性的研究

通过对辣椒不同品种幼苗不同节位叶柄的组织结构横切进行观察.结果表明,不同品种辣椒维管束间细胞层数相对稳定,叶柄中维管束间细胞层数约为10;随着节位的变化,其皮层细胞层数、横切直径大小略有差异,其中第2、4节位细胞层数最多,横切直径最大;皮层内大的薄壁细胞直径与维管束两端口间距离、维管束面积及叶柄横切面积显著相关,相关系...

Analysis on quantity characteristics of pepper petiole' s anatomical structures

This paper mainly based on the observation of cross-section organizational structure of different varieties of pepper seedlings’ petiole in different nodes.The results showed that the cell layers of vascular bundle of different peppers were relatively stabile.The number of cell layers between the vascular bundles in petioles was about 10;with the change of nodes,the cortical cell layers and the diameter of cross-section were slightly different,of which the second node and the fourth node had both the largest cell layers and the largest cross-section diameter;the cell diameter within the biggest cells in dermal epithelium was relative with the distance between two extreme of vascular bundle,vascular bundle area,petiole transaction area.The related figures were 0.984,0.964,and 0.985,respectively.The distance between two extreme of vascular bundle was relative with the vascular bundle area and the petiole transaction area.The related figures were 0.936 and 0.987.The vascular bundle area was relative with the petiole transaction area.The related figure was 0.964.Description petiole vascular thickening and related developmental level.
