Abstract: Flowering is the transition from vegetative growth to reproductive growth in plants. Flowering-related gene expression is the basis for achieving this transition. Environment factors and the growth conditions of plant cells on the expression of these genes play regulatory roles. Now, it has been
known that photoperiod stimulation signal was received and apperceived by mature leaves of plants and there are produced flowering signal substances in the mature leaves of plants, and that this kinds of flowering signal
substances transports from leaves to the top of stems, and ultimately causes flowering using model plants Arabidopsis, rice and ornamental plants petunia and Antirrhinum. This article reviewed the study progress in the molecular mechanisms of controlling flowering of plants, in order to provide references for further in-depth studies of photoperiodic flowering molecular mechanism of ornamental plants.

Key words: photoperiod, induction, plant, flowering, molecular mechanism
