The effects of top light treatment with different light qualities〔NIR（near infrared light），R （red light），G（green light），UV-A（long wave ultraviolet light），B（blue light），red and blue combined light（3R2B，2R3B），W（white light）〕on the growth and fruit quality of Capsicum at night（19：00— 22：00，3：00—6：00）were investigated using Zhangshugang pepper as a test material in a plastic greenhouse．Results demonstrated that compared to the control group without supplementary light，blue light （B）treatment exhibited the most favorable impact on fruit quality．The content of capsaicin，ascorbic acid，flavonoid and carotenoid increased significantly，with increases of 12.35%，46.64%，37.52%，and 18.44% respectively．Additionally，pepper yield per plant significantly improved under B treatment with a remarkable increase of 20.64% compared to the control group．Pearson analysis revealed that fruit dry weight served as an excellent indicator for assessing both growth and fruit quality of capsicum plants．Cluster analysis and principal component analysis demonstrated that red and blue combined light（2R3B，3R2B）along with B alone exhibited superior light qualities while G，ultraviolet light（10U，20U）and NIR showed poor regulation capabilities．A comprehensive evaluation using the membership function method revealed that pepper plants exposed to B treatment had the highest average membership function value among all tested light qualities in facility cultivation．Blue light is the best light environment to improve the growth and fruit quality of pepper．
