LIFE CYCLE OF PHYSARELLA OBLONGA
针箍菌的生活史

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.
