摘　　要：以"余干"辣椒为试材,在水培条件下,设置了6种光质,红光、蓝光、红光∶蓝光=4∶1、红光∶蓝光=8∶1、红光∶蓝光∶绿光=4∶1∶1和红光∶蓝光∶紫外光(UVB)=20∶5∶1,测定分析了辣椒在生殖期的形态建成、结果情况和果实品质变化,研究LED光质对辣椒生殖生长和果实品质的影响。结果表明:红光处理下"余干"辣椒株高最高,显著高于各复合光处理;蓝光处理下分枝数最多为4.11,开花时间最晚为44d,挂果数量最低为8.25个,果长/果宽最高为2.71,且与其它处理间有显著性差异;各复合光处理间植株生长和结果表现无显著性差异。红光∶蓝光∶UV-B=20∶5∶1处理下,维生素C含量最高,显著高于红光及各复合光处理,蓝光处理下,可溶性蛋白质含量极显著高于其余处理,红光处理下可溶性糖含量最高,显著高于蓝光处理。To study the effect of LED quality on reproductive growth and fruit nutrition quality of ＇Yugan＇ pepper,six light quality with blue light,red light,red light ： blue light=4 ： 1,red light ： blue light=8 ： 1,red light ： blue light ： green light=4 ： 1 ： 1 and red light ： blue light ： UV-B=20 ： 5 ： 1 were used in hydroponics and the changes of morphogenesis, reproductive growth and fruit quality were analyzed. The experimental results showed that the plant height was the highest in red treatment and was significant higher than that in other composite treatments. In blue light treatment, the branching number of 4. 11 and fruit length/width of 2. 71 were the highest and the flowering time for 44 days was the latest and the fruit number of 8. 25 was the least, which was significant difference from other treatments. There was no significant difference on the growth and fruits in all the composite light treatments. The vitamin C content was the highest in red ： blue ： UV-B= 20 ： 5 ： 1 and was significant higher than red light and composite light treatments. The soluble protein content in blue light treatment was significant higher than the other treatments. In the treatment of red light the soluble sugar content was the highest and significant higher than blue light.
