摘　　要：目的研究不同光质对萝卜芽苗菜的营养品质的影响。方法采用新型半导体光源发光二极管(LED)精量调制(红光、蓝光、和红蓝混合光)培养萝卜芽苗菜,以发白光(普通日光灯)为对照。结果红蓝混合光、蓝光处理下萝卜芽苗菜的维生素C(VC)、蛋白质含量显著高于白光和红光处理,但是蓝光显著提高了硝酸盐含量。红光处理下萝卜芽苗菜的粗纤维含量最高,而且VC、类黄酮、硝酸盐、蛋白质含量最低。白光显著提高了萝卜芽苗菜类黄酮含量。结论红蓝混合光处理下萝卜芽苗菜的营养品质最好,红光处理最差。Objective The effects of different light qualities on nutritive quality of radish sprouts were studied.Methods Radish sprouts were cultured in red light,blue light,red/blue light generated by light-emitting diode applied,and white light generated by fluorescent lamps was used as control.Results The contents of vitamin C（VC） and protein were the highest under the red/blue light and blue light,but the nitrate content was significantly increased under the blue light.The crude fibre content was the highest and the contents of VC,flavonoids,nitrate and protein was the lowest under red light.The white light was the most effective for the increase of the contents of flavonoids.Conclusion The nutritive quality of radish sprouts was best when grown under the red/blue light,and was worst under red light.
