通过对北京农学院常见的几种野生蔬菜及两种栽培蔬菜叶片横切面的解剖观察，发现野生蔬菜中Ｃ４植物在“花环”结构、叶绿体在维管束鞘及叶肉细胞内分布的数量和大小、组织结构等方面与Ｃ３植物存在着明显的差异，而同属于Ｃ３植物的野生蔬菜和栽培蔬菜间无明显差异，本研究为野生蔬菜栽培利用提供了理论依据。 The anatomical observation of cross-section of leaves of several wild vegetables and two cultivated vegetables common to Beijing Agricultural College found that the quantity and size distribution of C4 plants in “garland” structure, chloroplast in bundle sheath and mesophyll cells in wild vegetables were found, Structure and other aspects of C3 plants and there is a clear difference between the same belonging to the C3 plants of wild vegetables and cultivated vegetables no significant difference in the study for the cultivation and utilization of wild vegetables provides a theoretical basis.
