摘要：

The endogenous polyaminc levels were tested at every developmental stage in different ecotypes of the Chinese cabbage. The results showed that polyamines (PAs) were decreased in the process of flower bud initiation and formation, but the floral stem formation and elongation were accompied by PAs increase. The level of Spm was related to the bolting date of Chinese cabbage. During the inducing of flower bud initiation and elongation of floral stem, and the changes of Spm were reversed between early bolting date and late bolting cultivars, but they have the same requirment for Spd for the starting of flower bud initiation and the starting of bolting. The level of Spd changed little during entire developmental stage for early bolting cultivars, but a lot for late bolting cultivars. The time that the highest level of Put appeared is related to the bolting date of Chinese cabbage.
