Studies on growth properties of nematode-trapping fungi

The author reported the growth properties, incluing developing process and characteristics of hyphae, conidia, chlamydospore, and nematode trapping organs on 0.4 g/L CMA media or on 0.4 g/L LCMA media. The results showed that the hyphae of nematode trapping fungi branched radiantly on 0.4 g/L CMA media. The hyphae like cotton fibre of some fungi can be seen in 0.4 g/L LCMA. Conidia were on the top of conidiophores and appeared at the later stage of hyphae growth. Chlamydospore were produced intercalarily by hyphae cells when the fungi grew older, which were related to the species of nematode trapping fungi. The trapping organs only induced by living nematode larvae, but nematode eggs or adults.
