【摘要】 沈阳地区‘春香’草莓花芽分化始于9月中旬,结束于10月下旬。花芽分化时期从解剖形态上可分为:分化初期,花序分化期,花器分化期。花芽分化适宜温度为10℃-20℃。在短时照条件下,25℃以上不能形成花芽,5℃以下花芽分化被迫停止。所以,温度是影响花芽分化的关键因素。更多还原

The optimum temperature of flower bud differentiation is 10℃-20℃ under the condition of short days, the flower bud becomes unable to differentiate above 25℃ and below 5℃.
