【摘要】[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。%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. 【总页数】3页(2081-2083) 【关键词】甜荞;EMS;发芽率;发芽势 【作者】刘建霞
