摘要
试验结果表明，在水、气等条件适宜的情况下，四棱豆种于萌发所需最低温度为１１℃，最适温度为２６～２９℃，最高温度为４１℃，当≥１１℃的有效积温达７０℃以上时，种子萌发。种子出苗所需最低温度为１３℃，最适温度为２６℃，最高温度为３８℃，当≥１３℃的有效积温达１０６℃以上时。
The results of experiments in our laboratory showed that the minimum,optimal and maximum temperatures required for seed germination of winged beau were 11℃,26￣29℃ and 41℃, respectively, when other conditions (water, air etc.) were fit for seed germination. As the available accumulated temperature of ≥11℃ was over 70℃, seed germinated. However, the minimum, optimal and maximum temperatures required for seedling emergence were 13℃, 26℃ and 38℃, respectively. As the available accumulated temperature of ≥13℃ was over 106℃,seedling emerged.
