Abstract: At present，it has made breakthrough progress about the research of higher plant flowering mechanism. Along with epigenetics research more and more thoroughly，it has made some theoretical achievements although the study of the linkage between flowering control and epigenetic is still in the preliminary exploration stage. The author summarized present situation about the role of common epigenetics（DNA methylation，histone modification，non-coding RNA，chromatin remodeling）in different flower induction pathway. The purpose of this paper is to provide reference for the study which through the epigenetic technology to regulate flowering-time.

Key words: DNA methylation, epigenetic, histone modification, non-coding RNA, regulation of flowering time
