摘　　要：通过室内观察金灰藓[Pylaisiella polyantha(Hedw.)Grout]孢子在4种培养基质和不同p H梯度下的萌发情况,筛选出玻片-琼脂培养法是研究藓类植物室内生长发育的有效方法,适于跟踪观察孢子的生长过程,p H 6.0为金灰藓原丝体生长的最适p H值,原丝体在此环境中生长发育最快。并对孢子萌发及原丝体系统发育的时间及外界环境因子的影响进行分析与讨论。Through observing the spore germination of Pylaisiellapolyantha under 4 culture medium and different pH values, the paper concluded that slide-agar cultivation method is the effective method which can trace the spore growth process, and the optimal pH value is 6.0 in which the spore grew with the fast speed. The eharacteristicsof spore germination and protonema development a.s well as the influences of external environment factors are also analyzed and discussed.
