摘　　要：以中花芥蓝为材料 ,设置 4个不同的温度处理研究了苗期温度对芥蓝的生长发育、菜薹形成与品质的影响 .结果表明 ,苗期温度与芥蓝的生长发育关系密切 ,低温可促进花芽分化 ,随着温度的升高 ,花芽分化逐渐推迟 ,分化时的叶位也逐渐升高 .适宜的低温可促进植株生长 ,提高菜薹产量与品质 .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. Suitable low temperature could promote plant growth and increase the yield and quality of flower stalks.
