"Aquatic Botany" . "Populations of Phragmites australis (CAV.) TRIN. ex STEM were studied in the littoral zones of two man-made lakes located in the Trebon Basin (South Bohemia, the Czech Republic): (1) Opatovicky fishpond, a shallow artificial lake constructed in 1510-1514 by damming a shallow valley and used since for carp production, and (2) Halamky sand pit, a new lake formed by sand extraction in 1970-1994. Phenotypic variability was assessed on the basis of shoot morphological and growth characteristics, measured at the time of seasonal maximum aboveground biomass. Genotypic variability was detected using RAPDs, which demonstrated a high clonal diversity in both habitats. The clonal diversity would be strongly underestimated if it were based only on morphological differences. Higher genotypic variability was found in the fishpond reed, not corresponding with low variability in its phenotype performance. Based on analysis of 160 samples, four patterns of genotypic variation were detected: (1) Some stands were geneti"@en . . "\u010C\u00ED\u017Ekov\u00E1, Hana" . . "\u010Curn, Vladislav" .
