Selective adaptation to copper of populations ofAgrostis tenuis andFestuca rubra (Poaceae)

Abstract

Populations ofAgrostis Tenuis andFestuca rubra, tolerant and non-tolerant towards Zn and Pb, were studied in regard to their adaptability by natural selection, towards a third metal (Cu) and the time required for the appearance of such tolerance. It was found that Zn and Pb tolerant and non-tolerant populations are likely to select the character of Cu-tolerance within the course of only one generation. More specifically, Zn and Pb tolerant populations show a better adaptability compared with non-tolerant ones. The amount of tolerance to copper obtained by artificial selection is comparable with that of populations growing naturally on copper mines.
