Abstract：Taking 2 different spring cabbage(Brassica oleracea L.)varieties‘2006042’and‘Chunfeng’as materials,the paper observes their development process of flower bud differentiation by petrolin sectioncutting method and analyzes the changes in physiological and biochemical indexes during different development stages.The results show that the budding process of bolting susceptible cabbage‘2006042’is about 8 days earlier than that of the bolting tolerant cabbage‘Chunfeng’.The analysis of soluble protein in‘2006042’with SDS-PAGE finds three special protein bands(48.4 kD,18.8 kD,14.5 kD)are expressively re-enforced,and at the same time the band(84.0 kD)is disappeared and the band(17.4 kD)is weakened.This indicates that the above mentioned proteins have very close relation with bolting.The contents of soluble protein content and sucrose in‘2006042’are higher than that in‘Chunfeng’.
