Studies on thermoprotection induced by heavy metal ions in spring barley seedlings

Barley seedlings (Hordeum vulgare L., cv. Fatran) were pretreated with various concentrations of five heavy metal ions (Zn, Cu, Fe, Mg, Mn) for 3 d. When the subsequent heat shock was administered for 2 h, the heavy metal ions had thermoprotective effect against the sub-lethal (40 °C) and lethal (45 °C) temperature stresses, which were otherwise lethal to control (water grown) seedlings. The effectiveness of each of the heavy metal ions was different, the most effective being Cu. The level of protection provided by these heavy metal ions was dependent on both the time and the concentration that plants were exposed to them. The greatest differences were recorded in the thermotolerance mediated by applied metal ions in the shoot and root cells. Thermotolerance was exhibited by both the shoot and root of pretreated seedlings, even though the heavy metal stresses were applied solely to the roots.
