Abstract

Abstract: In order to research the effects of low temperature on flowering of Chinese cabbage,the paper studied the effect of low temperature on flowering of Chinese cabbage and analysed the change trend of the content of soluble sugar,pritein,starch and hormones in both germinating seeds and seedlings during cold treatment using common variety Y oudonger′ as experimental material.The results showed that both germinating seeds and seedlings of variety youdonger can be induced to flowering by low temperature treatment.During cold treatment,the content of soluble sugar in both germinating seeds and seedlings increased,the starch and protein decreased and the total C/ N ratio increased.In addition,cold treatment of germinating seeds made the content of G A and IAA in plants increasing,the content of ABA decreasing,at the same time,G A/ ABA and IAA/ ABA also increased,but G A/ IAA went down and rose later.Cold treatment of seedlings not noly made the content of G A,IAA and ABA increasing,but also made G A/ ABA,G A/ IAA and IAA/ ABA increasing.It suggested that the increase of relative content of G A and IAA is benefit to floweringof the Chinese cabbage.
