Název v původním jazyce

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

Popis výsledku v původním jazyce

Population of Phragmites australis were studied in the littoral zones of two human made lakes in the Třeboň Basin (South Bohemia, Czech Republic): Opatovický fishpond (founded in 1510-1514), and Halámky sand pit (formed by sand extraction in the 1970-1994). Clones were identified using RADPs 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 results indicate that the genetically determined morphological features (especially shoot length) are manifested more fully in the phenotype of the plants of the younger (Halámky) population, whereas environmental factors affect the phenotype to a greater extent in the older (Opatovický) population.
