摘　　要：以发光二极管(LED)蓝光(B),红蓝组合光(RB)(红∶蓝=8∶3和7∶3)和白光(W)为光源,研究了不同光质、不同补光时间对设施越冬辣椒Capsicum frutescens果实品质和产量的影响。结果表明:①蓝光有利于果实可溶性固形物、可滴定酸、可溶性蛋白、游离氨基酸和类胡萝卜素的合成;红蓝83光可促进可溶性总糖、维生素C和可溶性蛋白的形成;白光可提高果实叶绿素、总黄酮和可溶性蛋白的质量分数;红蓝73光有利于总多酚和可溶性蛋白的合成;②蓝光能促进果实横向生长,红光能促进果实纵向生长,红蓝光有利于果实膨大且提高果实商品性;红蓝83和红蓝73补光8 h时,辣椒的商品率、结果率和产量与对照差异极显著(P<0.05),且前者好于后者。生产上推荐红蓝83补光8 h为设施越冬辣椒生产的最佳补光光源及补光时间。To investigate the effect of different light-emitting diodes （LEDs） on the quality and yield of over- wintering Capsicum frutescens （peppers） in the greenhouse, a field trial was conducted with [blue （B）, red- blue （8：3,RB83）, white （W）, and red-blue （7：3, RB73） ~ LEDs and supplemental time per day （10 h, 8 h and 6 h）.The results showed that B was conducive to the synthesis of soluble solids, titratableacids, soluble proteins, free amino acids, and carotenoids; RB83 could promote the formation of soluble sugars, soluble pro- teins, and vitamin C （Vc）; W was effective for the increase in chlorophyll, total flavonoids, and soluble proteins; and RB73 could be beneficial for total polyphenols and soluble protein synthesis. Also, B promoted lateral growth and red （R） promoted longitudinal growth; whereas, RB was good for fruit enlargement and marketabili- ty. The yield, commodity rate and fruiting rate of pepper were very significantly higher （P〈0.01） than control when exposed to RB83 or RB73 for 8 h with RB 83 better. Thus, for overwintering pepper, RB 83 applied for 8 h under field conditions is recommended.
