growth, and contents of antioxidants in wheat roots is studied. The metals were added in
two concentrations to the nutrient solution for seedlings, and the higher one had a stronger
effect on the studied parameters. The heavy-metal tolerances of 8 wheat varieties are compared
in order to select the most tolerant (Kuial’nik) and most sensitive one (Sonechko) for biochemical
studies. The heavy-metal uptake and, subsequently, the lipid peroxidation are smaller
in the tolerant genotype, than in the sensitive one. The higher glutathione concentration in
the tolerant genotype under control conditions could contribute to the improved heavy-metal
tolerance. The metal-induced decrease in the glutathione content can be an indicator of the
increased phytochelatin synthesis. The great tolerance of Kuial’nik can be explained by its
decreased heavy-metal uptake and the greater glutathione-based antioxidant capacity. |
