为探讨PEG-6000溶液对苦荞种子萌发的影响，采用浓度为10％、20％、25％、30％的PEG-60（O溶液对川荞1号种子进行12h，24h，36h处理，以测定川荞1号种子的发芽率、发芽势、芽鲜重、芽干重与芽长，并计算其简单活力指数．结果表明：浓度为25％的PEG-6000溶液引发可以有效提高苦荞种子的发芽率，其显著性明显高于其他浓度，且在此浓度下处理24h的苦荞种子发芽率显著高于其他处理；不同的引发时间均可以提高苦蓑种旱确古孳盎7-,l者’dh出引发13h知36h韵芒莱种子发芽能力高，但差异不显著。

To study the polyethylene glycol （PEG-6000） solution priming on the germination of buckwheat seeds,the PEG-6000 concentration of 10% ,20% ,25% ,30% and 12 h,24 h,36 h of priming time were adopted to study on Seed I of Sichuan buckwheat respectively to determine the seed gemaination rate, germ- inative force, shoot fresh weight, shoot dry weight, bud length, and to calculate the simplified vigor index. The results show that：concentration of 25 % PEG-6000 solution can effectively improve the germination rate of buckwheat seeds, which is significantly higher than those of other concentrations. At this concentration, the rate of 24 h of priming time is significantly higher than those of priming times; different priming times can improve the germination rate of buckwheat seeds, germinating ability of the buckwheat seed under 24 h is more than that of 12 h and 36 h, but the difference is not statistically significant.
