| 摘 要： | 采用幼苗萌发法，在湿润和淹水两种水位萌发条件下，研究了蚌湖（鄱阳湖子湖）湖滨带5个水位梯度区的土壤种子库特征。结果表明，种子库中共萌发了33个物种，分属15科29属。物种组成以一年生草本为主，其中莎草科、禾本科、菊科、玄参科和水鳖科的物种数最多。不同水位区种子库的物种组成和幼苗密度差异不显著。种子库在两种水位条件下萌发的结果有显著差异，湿润条件下种子库萌发的物种以湿生和挺水植物为主，而在淹水条件下萌发的沉水植物种类和幼苗数量显著增多，其幼苗密度占总幼苗数的36％。t检验表明种子库在淹水条件下每个萌发盒中萌发的物种数（7．2±2．8）显著多于湿润条件（4．2±2．0）。 |

| Abstract: | Characteristics of soil seed banks in the lakeshore marsh of Bang Lake,a part of Poyang Lake,were studied under moist and inundation conditions using the germination test.A total of 33 species belonging to 15 families and 29 genera were recorded in the seed banks,with most being annual herbs.The most abundant families were Cyperaceae,Gramineae,Compositae,Scrophulariaceae,and Hydrocharitaceae.There was no significant difference in species richness and seedling density among water level zones.A total of 21 sp... |
