[目的]检测EMS诱变浓度和诱变时间对甜荞种子发芽的影响。[方法]以“晋荞麦3号”为材料，用 EMS诱变剂（设置不同诱变浓度和诱变时间）对甜荞种子进行诱变，测定其发芽率、发芽势、相对发芽率和相对发芽势。[结果]随着EMS诱变浓度的增加和诱变时间的延长，甜荞种子的发芽率、发芽势、相对发芽率和相对发芽势都呈下降趋势， EMS诱变甜荞的最适浓度为1.0%，处理时间为4 h，致死浓度为1.7%。[结论] EMS诱变浓度和诱变时间对甜荞种子发芽均有显著影响。
[目的]檢測EMS誘變濃度和誘變時間對甜蕎種子髮芽的影響。[方法]以“晉蕎麥3號”為材料，用 EMS誘變劑（設置不同誘變濃度和誘變時間）對甜蕎種子進行誘變，測定其髮芽率、髮芽勢、相對髮芽率和相對髮芽勢。[結果]隨著EMS誘變濃度的增加和誘變時間的延長，甜蕎種子的髮芽率、髮芽勢、相對髮芽率和相對髮芽勢都呈下降趨勢， EMS誘變甜蕎的最適濃度為1.0%，處理時間為4 h，緻死濃度為1.7%。[結論] EMS誘變濃度和誘變時間對甜蕎種子髮芽均有顯著影響。

Objective] This study aimed to investigate the effects of induced concen-tration and time of EMS on seed germination of common buckwheat. [Method] The seeds of Jinqiaomai No.3, a common buckwheat cultivar, were used as the test material, and their germination was induced by different concentrations of EMS un-der different induced times. The germination rate, germination vigor, relative germi-nation rate and relative germination vigor of Jinqiaomai No.3 were measured. [Re-sult] With increased induced concentration and time of EMS, the germination rate, germination vigor, relative germination rate and relative germination vigor of Jinqiao-mai No.3 were al trended to be decreased. For Jinqiaomai No.3, the optima in-duced concentration and time of EMS was 1.0% and 4 h, respectively, and the lethal concentration was 1.7%. [Conclusion] The induced concentration and time of EMS al showed significant effects on seed germination of Jinqiaomai No.3.
