摘要：
We studied the influence of a synthetic cytokinin-like growth regulator (Cytodef) and heavy metal ions—Pb2+, Sr2+, Zn2+, and Ni2+—on generation of superoxide anion (O2⊙−), lipid peroxidation, and carotenoids content in leaves of 7-day-old cucumber plants (Cucumis sativus L., cv. Izyashchnyi). In some instances Cytodef reduced the toxicity of heavy metals: it mitigated the negative effect of metals on oxidative processes and elevated the concentration of antioxidants (carotenoids).
