摘要
研究了温度、pH和后熟处理对缩球囊霉(Glomus constrictum Trappe)孢子萌发的影响,结果发现从云南热带植物河口观音座莲(Angiopteris hokouensis, Ching)根际土壤中采集的缩球囊霉孢子萌发的最适温度在25℃~30℃之间,最适pH在5~6之间,后熟处理明显能提高缩球囊霉孢子的萌发率;同时还观察到缩球囊霉孢子萌发时只产生一根芽管;缩球囊霉孢子的萌发率较其他一些VA菌根真菌孢子的萌发率低,不同季节采集到的孢子其萌发率有明显的差异。
The influence of temperature, pH and aging storage on the germination of Glomus constrictum spores collected from the rhizosphere soil of Yunnan tropical plant Angiopteris hokouensis Ching were studied. It was found that the optimum temperature for the spores to germinate was 25℃-30℃, and the optimum pH was 5-6. Aging storaged at 4℃ for two months could obviously increase the germination of Glomus constrictum spores. The spore of Glomus constrictum has just one germ tube when it germinated, and the germination rate was relatively lower than other arbuscular mycorrhizal fungi spores. The germination rates differed significantly in Glomus constrictum spores collected in different seasons.
