摘  要：
选用奶油生菜为试验材料,研究了白光(CK)、红光(R)、蓝光(B)、不同比例红蓝光等6种光质对生菜生长发育、叶片光合特性及品质的影响。结果显示:不同光质对生菜生长的影响不同,R处理下生菜的地上部分干、鲜质量及叶面积最大,R︰B=1︰1、R︰B=1︰2次之;R︰B=1︰2处理下生菜叶片中叶绿素a/b最大,R︰B=2︰1、R︰B=1︰1、R︰B=1︰2处理均可提高生菜叶片的净光合速率;R处理有利于生菜叶片中糖分的积累,R︰B=2︰1、R︰B=1︰1、R︰B=1︰2处理下生菜可溶性蛋白含量提高,R︰B=1︰2处理更有利于生菜VC含量的增加。综合各项指标,R︰B=1︰2处理下生菜的产量及品质最佳。

摘  要：
The study investigated the effects of red light(R), blue light(B), different ratios of R to B treatments by white light as control(CK) on the growth, photosynthetic characteristics and quality of butterhead lettuce. The results showed that different light treatments had different effects on the growth of lettuce. The shoots fresh and dry weight and leaf area were greatest under R treatment, closely followed by R︰B=1︰1 and R︰B=1︰2. Chlorophyll a/b under R︰B=1︰2 treatment was biggest. Under R︰B=2︰1, R︰B=1︰1 and R︰B=1︰2 treatments, the photosynthetic rates of lettuce leaves were increased. R treatment was beneficial to the accumulation of sugar in lettuce leaves. R︰B=2︰1, R︰B=1︰1 and R︰B=1︰2 treatments could increase the content of soluble protein. The treatment of R︰B=1︰2 was more conducive to the increasing of VC content. According to the comprehensive analysis of various indicators, the yield and quality of lettuce performed best under R︰B=1︰2 treatment.
