摘要： 为探讨果皮结构与籽粒柔嫩性的关系，研究了T4、T5、T19、T38和T39等5个超甜玉米(Z. mays subsp. mays)自交系籽粒不同发育时期的解剖结构。结果表明甜玉米果皮由多层细胞构成，最外层细胞排列紧密，细胞壁角质化。食用品质口感良好的T38和T39自交系具有果皮薄、细胞层数少、果皮细胞壁纤维化和木质化程度低等特征；T4和T5具有果皮厚、构成果皮的细胞层数多和果皮细胞壁纤维化和木质化程度高等特点，口感较差；T19果皮细胞密度大，细胞纤维化和木质化程度极高，在这5个自交系中口感最差。

Abstract: In order to understand the relationship between kernel tenderness and pericarp structure, histological studies of a set of super-sweet corn (Z. mays subsp. mays) inbred lines (T4, T5, T19, T38, and T39) kernels at different developmental stages were conducted. The result indicated thatsuper-sweet cornpericarp was formed with several layers of cells, where the outermost layer of cells packed tightly with horny cell walls. T38 and T39 inbred lines had a good eating qualities due to their thinner cell walls and less cell layers of pericarp combining with lower level of fibrosis and lignification of cell wall. On the contrary, T4 and T5 inbred lines did not have a eating qualities with thicker cell walls and more cell layers of pericarp combining with high level of fibrosis and lignification of cell wall. T19 had the worst taste for its high-density pericarp cells adding very high fibrosis and lignification of cell wall among the five inbred lines.
