狼毒大戟的小孢子发生与雄配子体发育

采用石蜡制片技术研究了狼毒大戟（Euphorbia fischeriana）的小孢子发生及雄配子体发育过程，结果表明：狼毒大戟的花药为四分孢子囊，花药壁为五层，发育为基本型;变形绒毡层，细胞为双核；小孢子母细胞减数分裂中的胞质分裂为同时型；四分体排列通常为四面体型，少数左右对称型;成熟花粉为三细胞型，椭球形，具三沟孔。研究结果为狼毒大戟的生物学研究及应用开发积累基础资料。

Microsporogenesis and Development of Male Gametophyte of Euphorbia fischeriana

The microsporogenesis and the development of male gametophyte of Euphorbia fischeriana were studied in this paper. The results show that the anther has four locules with wall composed of five layers of cells, and the anther development of the species is basic type, the amoeboid tapetum consists of binuclear cells; the cytokinesis in the meiosis of microspore mother cell is simultaneous; tetrads are usually arranged in tetrahedron and a few of them are bilateral symmetry; the mature pollens are elliptic in shape and belong to the three-cell type with three colporates. This article for E. fisheriana biology research and application development accumulation basic data.
