Abstract: In this review, the concept, types and affecting factors of flowering reversion were introduced, and the progresses of morphological, physiological and molecular_biological researches on this phenomenon were reviewed. The authors also discussed the possibility of using flowering reversion in the study of plant developmental biology. It was put forward that a novel experiment system consisting of flowering, vegetative growth and flowering reversion can be established to improve the reliability of the results in the studying of the mechanism of photoperiod responses of plants, especially in the studying of the related genes expression concerning with mechanism of flowering.
