The content of reduced glutathione (GSH) and glutathione-S-transferase (GST, EC 126.96.36.199), glutathione-peroxidase (GPX, EC 188.8.131.52) and glutathione-reductase (GR, EC 184.108.40.206) activity in Acer platanoides and Acer pseudoplatanus seeds from contaminated phytocenoses were determined. Species-specific and coordinated changes of GSH pool and glutathione-dependent enzymes activity confirm the participation of glutathione cycle in the implementation of different adaptation strategies of Acer species to pollutants chronic action.
