Chinese cherry varieties Zhujiduanbing and Heizhenzhu were used as materials in this study.LED light sources with different power,incandescent light source,and commodity light source were used for light filling during the fruit core-hardening period to the harvest period,and natural light as control.Physiological indexes of plant and fruit quality indexes were tested.The results showed that the red/blue(6∶1)LED light supplementation treatment significantly increased the photosynthetic rate of leaves and promoted the fruit de-velopment and coloration.The 36 W LED light supplementation increased the fruit size of Zhujiduanbing and Heizhenzhu,and increased the soluble solid sugar content of the two varieties to 77.48 mg/g and 74.40 mg/g.LED light supplement played a positive role in promoting nutrition growth and improving fruit quality of cher-ries,and was a cherry production technology worthy of research and promotion.
