本文对菜心（ＢｒａｓｓｉｃａｐａｒａｃｈｉｎｅｎｓｉｓＢａｉｌｅｙ）的菜苔形成过程内部结构特点，进行解剖学研究，为菜心优质丰产提供解剖结构依据。结果表明：从菜苔形成至采收期间，近茎端上段始终具分裂能力，皮层与髓部薄壁组织发达，细胞小，延长少，排列紧密，细胞间隙小而少，维管束小，未木化，为优质菜苔的标志；茎苔中段薄壁细胞不那么紧密，细胞间隙增多增大，形成层保持着分裂活动。菜苔有明显的节间伸长和增粗，维管束木质部大于韧皮部，品质不及上段；茎苔基部皮层与髓部薄壁组织明显疏松，细胞间隙多而大、维管束多而密，次生木质部比例大，导管大，多且木化，品质变劣，无食用价值。
In this paper, Brassica napus (BrassicaparachinensisBailey) in the process of formation of the internal structure of the ginseng, anatomical study for the quality of cabbage to provide anatomical basis for high yield. The results showed that during the period from the formation of canopies to harvesting, the upper segment of the proximal stem end always had the ability of division, the parenchyma of the cortex and the pith were developed, the cells were small, elongated less, arranged closely, the cell gap was smaller and smaller, the vascular bundle was smaller, Woody, high-quality signs of moss; stem moss parenchyma cells are not so close, increased cell gap increased, the formation of layers to maintain the division activity. Cauliflower obvious internodal elongation and thickening, vascular bundles of xylem than the phloem, the quality of less than the upper; stem moss cortex and parenchyma parenchyma significantly loose, large and large interstitial cells, vascular bundle more dense, secondary A large proportion of xylem, large catheter, and more wood, worse quality, non-food value.
