摘　　要：利用基物培养、燕麦-琼脂培养技术及扫描电镜技术研究了圈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,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形成阶段。琼脂培养基上获得的圈绒泡菌孢子与野生型相似,并具有可育性。Moist chamber culture method, oat-agar culture method and scanning electron microscopy were used to study the process of the individual development of Physarum gyrosum. The life cycle of spore-to-spore were completed in agar culture in Petri dish. The result shows that the life cycle of Physarum gyrosum comprises a unicellular amoeboid or swarm cell stage, a multinucleate plasmodium stage and a sporulation stage. Spores develop on agar are fertile and resemble those on natural substrate.
