试验以生菜为材料,利用LED精量调制光源,设置黄光( Y)、绿光( G)、红光( R)、蓝光( B)和红蓝组合光( R:B=3:1) 5个LED光处理,以镝灯白光为对照,探讨了不同LED光源对生菜生长和品质的影响.结果表明:红蓝组合光下生菜植株鲜样质量和干样质量最大,其次是蓝光处理.与对照相比,蓝光和红蓝组合光显著提高了生菜可溶性糖、可溶性蛋白、游离氨基酸和维生素C含量.试验还发现,红蓝组合光显著提高了生菜叶片中硝酸还原酶和谷氨酰胺合成酶活性,从而降低了硝酸盐和亚硝酸盐含量,有效提高了其安全品质.

The study investigated the effects on growth and quality of lettuce under six light treatments:yellow LED( Y) ,green LED( G) ,red LED( R) ,blue LED( B) and the red plus blue light ( R :B=3 :1) by dysprosium lamp as control ( CK) .The results showed that:under combination of red light and blue light,the fresh weight and dry weight were the largest,and the second is blue light treatment.Compared with the control,blue light and the red plus blue light significantly enhanced the content of soluble sugar, soluble protein,amino and vitamin C.The study also showed that the red plus blue light significantly im-proved activity of nitrate reductase and glutamine synthetase in lettuce leaf,which reduced the content of nitrate and nitrite and improve the safety effectively.
