The effect of different light quality of 3030 lamp beads on the activity of antioxidant enzymes was significant. The APX activity of rape seedlings increased significantly and the POD activity decreased after 9 days of red light treatment; the POD activity of tomato was 20.9% and 11.7% higher than that of white light after 15 days of red light and blue light treatment, respectively. The POD activity was the lowest after 20 days of green light treatment, only 55.4% of that of white light; the soluble protein of cucumber seedling leaves was significantly increased after 4 hours of blue light supplement Content, pod, SOD, APX, CAT activity. In addition, the activity of SOD and APX decreased with the increase of light duration. The activity of SOD and APX decreased slowly but was higher than that of white light. The activities of peroxidase, IAA peroxidase and IAA peroxidase in tomato leaves and eggplant leaves were significantly decreased by red light irradiation, but the activities of peroxidase in eggplant leaves were significantly increased. Therefore, the reasonable light supplement strategy of led3030 can effectively delay the senescence of Protected Horticultural Crops and improve the yield and quality.
