Abstract: The environmental signals, such as low temperature or so-caUed vernalization, play important roles on reguletion of growth and development of the higher plants. This paper reviews some research progresses in flowering studies from the following aspects: the multi-processes of vernalization, the multi-pathways in the floral determination, the relationship between the site of receiving the vernalizational stimulation and the initiation of differentiation, and the molecular mechanism of vernalization. Also introduced are the research achievements about cloning of vernalization-related genes.
