Bemerkungen/Beschreibung

Universität Wien, Dissertation: 1996, 328 pp
Eight different populations of Silene vulgaris originating from Austrian and Italian copper-mine wastes and three populations from uncontaminated sites were investigated. Metal tolerance was defined in short-term experiments by determination of the cytoplasmic tolerance to copper and zinc (Hoefler 1932). Some of the copper-tolerant ecotypes showed a co- tolerance (low-level tolerance) for zinc. A significantly enhanced cytoplasmic tolerance to copper could not be detected in any population. The copper tolerance correlated reversely with the copper contamination of the soil, since the most resistant plants were found on low metal contaminated sites of the mining area at Tofernalm near Huettschlag (Grossarltal, Salzburg). The same type of correlation was found with plants from solution cultures. The pattern of metal uptake and distribution varied considerably between the different populations. This indicates different mechanisms of copper tolerance and detoxification.
