- Abstract
The effect of zinc and copper on seed germination and growth in the first ontogenetic stages in the species Brassica oleracea L. var. acephala was investigated. Copper and zinc was used as sulphate solutions, in four different concentrations: 10 mg/l, 20 mg/l, 40 mg/l and 60 mg/l for copper; 100 mg/l; 200 mg/l; 300 mg/l and 400 mg/l for zinc. We analyzed the following indicators: the percentage of germinated seeds, the mean germination time, the length of the root, the length of the hypocotyl and the tolerance index. The following effects were found: the insignificant modifications of the germination percentage (with little excepts) and the mean germination time; the significant delay of the growth in length of the root and of the hypocotyl; the decrease of the tolerance index. The root was more affected compared to the hypocotyl.
