摘　　要：利用基物和燕麦-琼脂技术研究了针箍菌的个体发育过程,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。琼脂培养基获得的针箍菌孢子与野生型相似,并具有可育性。Moist chamber cultures, oat-agar cultures and scanning electron microscope were used to study the process of the individual development of Physarella oblonga. The life cycle of spore-to-spore were completed in agar culture in Petri dish.The result shows that the life cycle of Physarella oblonga 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 nature substrate.
