摘　　要：研究了不同光质[红光、蓝光、红蓝混合光、白光(CK)]对苜蓿芽苗菜生理特性及抗氧化酶活性的影响。结果表明,红光可显著提高可溶性糖含量,蓝光和红蓝混合光则降低了可溶性糖含量;蓝光处理的可溶性蛋白质含量、根系活力、过氧化物酶(POD)活性显著高于其他光质处理;红蓝混合光处理的维生素C含量和叶绿素含量最高,且叶绿素含量与百株鲜重的拟合方程的决定系数(R2)为0.930 9;不同光质处理的超氧化物歧化酶(SOD)活性之间无显著差异。红蓝混合光处理的百株维生素C含量和百株可溶性蛋白质含量均较高,红蓝混合光是苜蓿芽苗菜生产中较好的补光光源。The effects of different light qualities[red light,blue light,red-blue mixed light,white light(CK)]on the physiological characteristics and antioxidant enzyme activities of alfalfa sprouts were studied.The results showed that the soluble sugar content was significantly increased under red light,while blue light and red-blue mixed light reduced the soluble sugar content.The soluble pro-tein content,root activity and peroxidase(POD)activity with blue light were significantly higher than those of other light quality treat-ments.Compared with other light quality treatments,the vitamin C content and chlorophyll content with red-blue mixed light were the highest,and the determination coefficient R2 of the fitting equation of chlorophyll content and fresh weight per 100 plants was 0.9309.There was no significant difference in superoxide dismutase(SOD)activity between different light quality treatments.The vitamin C content per 100 plants and the soluble protein content per 100 plants with red-blue mixed light were higher.Red-blue mixed light was a better light source for supplementing light in the production of alfalfa seedlings.
