- Association Green-leaf pak choi had lower nutritional quality than red-leaf pak choi.
- Association Biomass and soluble sugar content were highest under the 1-hour light interval treatment.
- Intervention effect Chlorophyll a and total chlorophyll contents were significantly increased compared with control.
- Intervention effect Chlorophyll b showed no significant difference under any light treatment.
- Association Carotenoid content was highest under the 1-hour treatment in green-leaf pak choi.
- Association Carotenoid content was highest under the 4-hour treatment in red-leaf pak choi.
- Association Soluble protein content was highest in the 4-hour treatment.
- Association Nitrate content was significantly decreased in the 4-hour treatment.
- Intervention effect Vitamin C, phenolic compounds and flavonoid contents were significantly increased compared with 0 hours.
- Intervention effect Anthocyanin content was significantly increased compared with 0 hours.
- Association Vitamin C, phenolic compounds and flavonoids showed no significant differences among the 1-, 2- and 4-hour treatments.
- Association Anthocyanin content in red-leaf pak choi gradually increased with longer light intervals, highest in the 4-hour treatment.
- Association Supplemental alternating red and blue light slightly increased antioxidant capacity.
- Association Antioxidant capacity showed no significant differences after 1, 2 and 4 hours of treatment.
