The pollutants-induced changes of reduced glutathione content and glutathione dependent enzymes activity in vegetative buds of Acer trees were investigated. In buds of A. platanoides and A. pseudoplatanus increasing GSH pool and GST activity attached to high GR activity were established, whereas in A. negundo buds decreased GSH content but high induced GR and high constitutive GST activity were revealed. Specificity of vegetative bud’s glutathione system changes points to variations of pathway of Acer species metabolic adaptation to pollutants’ action.
