| 英文摘要 |
Spores and plasmodium of Reticularia lycoperdon Bull. were sectioned by electron microscopy. Organelles have been studied and described. The mitochondria were found particularly clear in both spores and plasmodium. The spore walls were thick. with coarse protuberances and usually were surrounded by a delicate slimy layer. Nuclear divisions were occasionally observed before the spore ruptured. The emerging of the swarm cells. possibly 1-4 from each spore, came out through a crack (6) in the wall, Some of the swarm cells were transformed into myxamoebae shortly after emerging. The myxamoebae moved rapidly, each showed only one flagellum at the tapering end. Fibrils were seen when protoplasmic streaming was active. The spore to spore culture was completed in about 16 days, and this is the first time it has been reported in science. |
