| 摘 要： | 通过对3个不同熟性大白菜的观察,将其花芽形态分化过程分为营养生长期、生长锥伸展期和花原基分化期3个时期,并将花原基分化期细分为萼片分化期、雄蕊和雌蕊分化期和花瓣分化期。所观察材料的侧枝分化顺序都是由顶部向基部依次进行。熟性不同的材料问花芽发育速度为极早熟>早熟>晚熟。

| Abstract: | The process of the floral bud differentiation of Chinese cabbage Brassica campestris L. ssp. pekinensis (Lour.) Olsson) cultivars was divided into three stages: the vegetative growth stage, apical cone extension stage and floral bud primordium differentiation stage. Forthmore, the third stage was divided into three phases; the sepal differentiation phase, stamen and pistil differentiation phase and petal differentiation phase. Lateral branch differentiation order was in a basipetal sequence. The differentiation of floral bud in early mature cultivars was earlier than late ones. |
