将‘粉皮’石榴的花芽分化分为7个时期,其中,胚珠分化期尤为关键。在安徽怀远,花芽的形态分化从6月上旬开始,历时2～10个月不等。花芽分化既连续,又表现出3个高峰期,即当年的7月上旬、9月下旬和4月上、中旬。花芽以花瓣期或之前的时期越冬。与花芽分化高峰期相对应的是3个开花高峰期,称为“头花”、“二花”和“三花”。石榴花芽分化要求较高的温湿条件。最适温度为月均温20±5℃。低温是石榴花芽分化的限制因素,月均温低于10℃时,花芽分化逐渐减弱直至停止。文中还讨论了石榴花序的类型等。
The flower bud differentiation of ’Fenpi’ pomegranate is divided into seven stages, among which the ovule differentiation stage is particularly important. Huaiyuan in Anhui, flower bud morphological differentiation from the beginning of June, which lasted 2 to 10 months. Flower bud differentiation is continuous, but also showed three peaks, that is, in early July, late September and April, mid. Flower buds in the petal period or before the winter. Corresponding to the peak of flower bud differentiation is the three flowering peak, known as the “first flower”, “two flowers” and “three flowers.” Pomegranate flower bud differentiation requires higher temperature and humidity conditions. The optimum temperature for the average monthly temperature of 20 ± 5 ℃. Low temperature is the limiting factor for the differentiation of pomegranate flower buds. When the monthly average temperature is below 10 ℃, the flower bud differentiation gradually weakened until it stopped. The article also discusses the type of pomegranate inflorescence.
