Phenotypic and genotypic variation of Phragmites australis: A comparative study of populations clones originating from two of different age

Popis výsledku v původním jazyce

Populations of common reed (Phragmites australis [Cav.] Trin. Ex Steud.) were studied in the littoral zones of two human-made lakes in the Trebon Basin (South Bohemia, Czech Republic): (1) Opatovicky fishpond, a 500-year-old fishpond, and (2) Halamky sand pit, a new lake formed by sand extraction in the 1970-1990s. Clones were identified using the RAPD method within morphologically different stands. The clones were propagated vegetatively and cultivated under comparable conditions in a common garden experiment for one vegetation season. Morphological and growth characteristics of the cultivated plants were recorded and compared with those found in the original reed stands. The younger (30-year old) population was genotypically more diverse than the older (500-year old) population. In addition, the younger population demonstrated correspondence of genotypic and phenotypic variation, while the older did not. The results indicate that the genetically determined morphological features (esp
