Abstract: The experiment was carried out with different application ways of 5-azaC on two varieties of broccoli ‘Qing-feng 103’ and ‘Lv-xiu’ in order to study the influences of DNA demethylation on vernalization, flower bud differentiation and flower-ball development in broccoli. The results showed that, the 5-azaC spraying could promote vernalization, advance flower-bud differentiation stage, rapid growth and initial harvesting period.
