摘　　要：综合运用光镜、扫描、透射电镜技术 ,观察兰靛果忍冬的大小孢子发生和雌雄配子体的发育过程。结果表明 ,花药壁发育属于基本型 ,变形绒毡层 ,四分体呈四面体型排列 ,小孢子母细胞的胞质分裂为同时型 ,3- c型花粉。柱头表面具大量乳突细胞 ;花柱细长 ,上部具明显的花柱道 ,下部实心 ,有发达的引导组织 ;子房下位 ,倒生胚珠 ,具珠被绒毡层 ,薄珠心 。Comprehensively utilizing optical microscopy、scanning and transmitting electron microscopy,this paper systematically studied the Development of female and male gametophyte of Lonicera edulis L.The results were as follows.1.Anther wall development followed the fundemental type,and the tapetum was amoeboid.Simultaneous cytokinesis in the microspore mother cells followed meiosis and the microspore tetrads were tetrahedral.Pollen grains were 3-celled when shed.2.The surface of stigma had a lot of papilla cells; the style was long and thin;there had many anatropous ovule in the ovary which was inferior;cytokinesis accompanied meiosis and the chalazal megaspore of a linear tetrad developed into a Polygonum type embryo sac
