The effects of temperature treatments [35/28 and 22/17 (℃, average temperature, day/night)] on growth and color of flower stalk were studied on Chinese kale (Brassica alboglabra Bailley) (cv. ‘Jianyexia’ and ‘Hongjiao’) in growth chamber. The results showed that the fresh weight of flower stalk and root, dry weight and leaf area of plant decreased under higher temperatures in both cultivars, and the reduction in cv. ‘Jianyexia’ was greater than in cv. ‘Hongjiao’. The anthocyanin concentrations in flower stalk decreased in both cultivars under higher temperature, and those in cv. ‘Hongjiao’ is significantly higher than in cv. ‘Jianyexia’. However, the flavonoid concentrations in flower stalk increased in both cultivars under higher temperature. There were little effects of temperature on concentrations of chlorophyll and carotenoid in flower stalk, and those of cv. ‘Jianyexia’ were significantly higher than cv. ‘Hongjiao’.
