The effects of four different temperature (18℃/12℃?24℃/18℃?30℃/24℃?36℃/30℃)treatments of seedling period on the flower bud differentiation, yield and quality of flower stalks were studied in Chinese kale . The results showed that temperature was close related to the growth and development. Low temperature caused earlier flower bud differentiation and lowered the differential leaf node. With the increase of temperature, flower bud differentiation was delayed and the differential leaf node became higher. Suit...
