中文摘要：

利用燕麦-琼脂培养、基物培养及扫描电镜技术研究了多头绒泡菌的个体发育过程,在燕麦琼脂培养基上完成了从孢子到孢子的生活史.结果表明,多头绒泡菌生活史包括单核的黏变形体或游动胞、多核的营养体原质团以及孢子的形成等阶段.孢子球形,表面具细小疣点;孢子萌发为裂式,释放黏变形体.原质团类型为显型;成熟原质团亮黄色,可形成多个孢囊.琼脂培养基上获得的多头绒泡菌孢子与野生型相似,并具有可育性.

英文摘要：

The life history of myxomycetes is of importance to study diversity of nutritive modes and phylogenesis of these organisms.Until now the reports concered were few.Oat-agar culture method,moist chamber culture method and scanning electron microscopy were used to study the process of the ontogeny of Physarum polycephlum.The life cycle of spore-to-spore were completed in agar culture in Petri dish.The result shows that the life cycle of Physarum polycephlum comprises a unicellular amoeboid or swarm cell stage,a multinucleate plasmodium stage and a sporulation stage.The spore is globose and the spore surface is minutely spiny.The spore germinates by means of a cracked open and releases a single myxamoeba.The plasmodial type is of phaneroplasmodium.The mature plasmodium is bright yellow,which can form many sprangia.Spores developed on agar are fertile and resemble those on natural substrate.
