摘要: 运用冬性有极显着差异的2个甘蓝材料(7224 9、旅141[5]424),对低温诱导花芽分化的温度、诱导的起始苗龄、诱导持续的时间及诱导后花芽生长的温度及时间进行了比较试验。提出以7~8叶苗龄、5℃低温诱导50d,光周期12h,而后转入昼温/夜温=25~30℃/15~20℃,15d,测定花芽分化级数,计算花芽分化指数,以此对甘蓝进行冬性鉴定。运用此方法,对2份自交系、8份春早熟组合进行了冬性鉴定。

Abstract: In the trial of testing standards and methods for cabbage winterness characteristics, the temperature of flower bud differentiation, the age of seedling, duration, temperature and duration after induction were tested. The experiment demonstrated that it was a proper method, in which cabbage seedlings with 7 8 leaves were treated at 5℃ for 50 days, with 12 hours lighting per day, before transferred the treatment at 25~30℃ (day) and 15~20℃ (night) for 15 days. The grades of flower bud differentiation were investigated, and calculated the flower bud differentiation index. The winterness for 2 inbred lines 8 spring early mature combinations were evaluated in this method.

Key words: Winterness, Flower bud differentiation, Assay method, Cabbage
