Abstract: The process of the floral bud differentiation of Chinese cabbage 【Brassica campestris L.ssp.pekinensis(Iour.)Olsson]cuhivars was divided into three stages:the vegetative growth stage,apical cone extension stage and noral bud pfimordium differentiation stag e. Forthmore, the third stage Was divided into three phases: the sepal differentiation phase, stamen and pistil diferentiation phase an d petal differentiation phase.Lateral branch diferentiation order Was in a basipetal sequence.The diferentiation of floral bud in early mature cultivars Was earlier than late ones.

Key words: Chinese cabbage, Bolting, Floral bud morphological diferentiation period
