摘要
对4个品种一品红进行光周期低温花期调节试验,实验20d左右后,花芽开始分化,苞片变红,40d左右花球外皮裂开露出子房,与对照组比较,开花时间显著提前。
The flowering of four species of Euphorbia pulcherrima was adjusted by photoperiod and low temperature, the result showed that the bract began to turn red about 20 days later, and the ovary was out after about 40 days, the trial groups' flowers came out much earlier than the contrast groups did.
