摘　　要：甜荞和苦荞是两种主要的栽培荞麦,为探讨果皮对荞麦种子萌发的影响,采用传统生物学测量法测定了不同荞麦品种种子的基本生物学特性。同时,采用室内生物测定的方法,比较了不同荞麦品种去果皮和未去果皮种子的萌发特性。结果表明,甜荞种子比苦荞种子大,具有更高的千粒重和萌发率,不同品种间的基本生物学特性存在差异;不同甜荞(赤甜1号除外)和苦荞品种未去果皮种子的最终萌发率均显著高于去果皮的种子(P<0.05),并具有更高的最高日萌发高峰,但不同品种间的萌发动态存在差异。可见,甜荞和苦荞果皮的存在有利于其种子的萌发,实际生产中可直接播种。Fagopyrum esculentum and E tataricum are two main cultivated species of buckwheat. In order to investigate the effect of pericarp on the germination of buckwheat, basic biological characteristics of different varieties of buckwheat were measured by traditional biological measuring methods, and the germination characteristics of the different varieties of buckwheat with pericarp and without pericarp were compared. The results showed that the seed size, thousand-seed weight and germination of E esculentum were higher than those of E tataricum; the final seed germination rates of different varieties of E esculentum （besides Chitian 1） and E tataricum with pericarp were significantly higher than those of the varieties without pericarp （P 〈 0.05）, and the former had higher daily germination peak, but the germination trends of different varieties were different. So, it could be concluded that the existence of the pericarp was helpful for the germination of the buckwheat, which could be used in the actual production.
