摘要：

The genetic structure of Potamogeton anguillanus in Lake Biwa, Japan was surveyed by enzyme electrophoresis. Polymorphic banding patterns were observed in four of eight enzymes investigated. Based on the combination of the single enzyme phenotypes, 27 multi-enzyme phenotypes (MEPs) were determined in the whole lake based on 258 shoot samples collected from 14 local populations. Most of the local populations were polymorphic and involved one to eight unique MEPs. A mapping survey of MEPs in selected quadrats showed establishment of ramets with different genotypes and the clonal spread of the species. The origin of genetic diversity in the species may partly be due to recurrent hybridization. Sexual reproduction may also be involved. (C) 2000 Elsevier Science B.V. All rights reserved.
