Abstract:

Maize is an important cereal crop that is sensitive to drought stress. There are differences in drought tolerance among different genotypes in response to drought stress. In this study, the effects of drought treatment on photosynthetic rate (Pn), antioxidant properties, and yield of maize leaves of different genotypes were analyzed by using six common maize varieties as materials and adopting split block design under field conditions in the suburbs of Beijing. The results showed that Pn of different maize varieties significantly decreased in Jingnongke 728 (15.63%) < MC703 (15.84%) < Nnonghua 101 (16.34 %) < Denghai 618 (16.92%) < Zhengdan 958 (19.15%) < Lianchuang 808 (21.74 %) by drought treatment. Under drought treatment, the activities of antioxidant enzymes (SOD, POD, and CAT) and the content of malondialdehyde (MDA) in maize leaves of different varieties were significantly decreased. SOD activities of Jingnongke 728 and MC703 were significantly higher than that of other cultivars, while POD activity, CAT activity, and MDA content were not significantly different among varieties by the drought treatment. Compared with the irrigation treatment, the effect of drought treatment on yield was significantly different among varieties, and the final yield reduction was Jingnongke 728 (15.47%) < Denghai 618 (17.62%) < Nonghua 101 (21.83%) < MC703 (26.20%) < Zhengdan 958 (27.41%) < Lianchuang 808 (27.30%).

Key words: Maize, Variety, Drought stress, Photosynthesis rate, Antioxidant enzyme
