The dose-dependent increase in proline in the culture of Feria was observed, while in 1014 its level increased only at the highest applied Cu concentration. The decline in proline content and decrease in embryogenic ability in the line 1014 grown in the presence of the highest Cu concentration may indicate that a certain threshold of intracellular Cu was crossed. The increased content of proline and higher contents of the constitutive free putrescine and spermidine in Feria cultivated for 24 weeks at the highest Cu concentration point to better protection of this cultivar. The higher tolerance of Feria to oxidative stress may result from higher constitutive level of PAs. These data confirm the suggestion that variations in PA levels depend not only on the concentrations of metals tested, but also on plant species and cultivars.
