Keywords: Cucumis sativus L., temperature drops, catalase, low molecular antioxidants, cold resistance

We studied the effects of continuous (CLT) and periodic short-term (DROP) low temperature exposure on catalase activity and low molecular antioxidant content in cucumber leaves. CLT inhibited catalase activity while promoting cold resistance, whereas DROP promoted catalase activity simultaneously with inducing a rise in cold resistance. We demonstrate that compared with the control CLT-treated plants had a higher content of low molecular antioxidants, whereas their content in DROP-treated plants was significantly lower or the same as in the control. Mutually compensating changes in components of the antioxidant system were observed in the response of the cucumber plants to the two low temperature effects.
