Ploidy levels and their relationships with the rainfall in several populations of Patagonian species of Berberis L

The ploidy levels and pollen staining of 68 populations belonging to 13 species of the genus Berberis L., growing in the Argentinian Patagonia under different environmental conditions, were analyzed as a part of a multidisciplinary study to obtain information about the evolutionary history of the ge...

Argentinian patagonia Basic chromosome number Berberis Polyploids The ploidy levels and pollen staining of 68 populations belonging to 13 species of the genus Berberis L., growing in the Argentinian Patagonia under different environmental conditions, were analyzed as a part of a multidisciplinary study to obtain information about the evolutionary history of the genus. The chromosome number at Berberis bidentata, B. cabrerae, B. chillanensis, B. darwinii, B. empetrifolia, B. ilicifolia, B. linearifolia, B. micro-phylla, B. montana, B. parodii and B. serrato-dentata is 2n = 28, whereas B. buxifolia and B. heterophylla have 2n 56. The relationship between ploidy levels and rainfall showed that, contrarily to the species with 2n = 28, B. buxifolia and B. heterophylla (2n =56) grow in areas where the rainfall range is low. The opening of new habitats for colonization as a result of climatic change provides an ecological opportunity for the polyploids to exploit their inherent advantage. © 1999 Taylor & Francis Group, LLC.
