摘要
为进一步研究苜蓿Medicago sativa秋眠性的生理机制,提高苜蓿的抗寒性和生产性能,研究了短日照(8 h光照/16 h黑暗)条件下,不同秋眠型对苜蓿超氧化物歧化酶(SOD)、过氧化物酶(POD)活性的影响。结果表明:苜蓿SOD、POD的活性随着秋眠性的增强而升高,呈现秋眠型苜蓿Vernal最高,半秋眠型苜蓿CW502次之,非秋眠型苜蓿CUF101最低的趋势;3种不同秋眠型苜蓿的SOD、POD活性均随着生长期的延长而升高。
The experiment was conducted to explore the relationship between fall dormancy and superoxide dismutase （SOD） and peroxidase （POD） activities of alfalfa under short day （8 h light/16 h dark） condition. The results showed that SOD and POD activities increased with the increase of fall dormancy, and the fall dormancy alfalfa （Vernal） was the highest and followed by the semi-fall dormancy alfalfa （CW 502）, and non-fall dormancy alfalfa （CUF101）; SOD and POD activities of three different fall dormancy alfalfa increased with the elongation of growth period.
