采用半薄切片方法定位，观察了枇杷（ＥｒｉｏｂｏｔｒｙａｊａｐｏｎｉｃａＬｉｎｄｌ．）受精前后雌蕊结构的变化，胚乳和胚的早期发育过程中传递细胞的分化、分布和存在时期，结果表明：柱头、花柱具传递细胞或传递组织；内珠被及珠心的部分细胞．壁内突显著；胚乳外层细胞为传递细胞型细胞；胶囊、中央细胞等均有局部壁内突现象或呈吸器，并且相互消长，文中讨论了传递细胞的分布特点以及对胚胎早期发育的营养作用． The semi-thin section method was used to locate the pistil structure of Eriobotrya japonica Lindl. Before and after fertilization, the differentiation, distribution and period of the passaged cells during the early development of the endosperm and the embryo were observed. The results showed that the stigma and the flowering cell passed the cells or passed Tissue; part of the inner beads and beads of cells. The inner wall of the endosperm protrudes prominently; the outer cells of the endosperm are cell-typed cells; the inner wall of the capsule, the central cells and the like are inhomogeneous, effect.
