摘要
Changes in the activity of catalase and superoxide dismutase, together with growth parameters were investigated in flag leaves of four winter triticale cultivars. Water stress was applied during shooting (D-s) or heading (D-h) stage. Dry matter of the main shoot and tillers was similarly restricted by both drought periods. The length of the main shoot was more constrained by D-s, in contrast to the number of tillers, restricted strongly by D-h. The resumption of growth after rehydration was clearer in cvs. Bogo and Tewo, and hence these two cultivars were considered more drought-resistant than Presto and Ugo. Neither catalase nor superoxide dismutase activity was influenced by the term of the drought and the genotype.
