摘　　要：为了探究低温贮藏年限对小粒大豆种子活力及幼苗质量的影响,以3种不同熟期的小粒大豆品种为试验材料,设置5个贮藏年限处理,研究低温贮藏条件下小粒大豆种子活力及幼苗质量的变化规律。结果表明:随着贮藏年限的增加,不同小粒大豆品种的种子活力和幼苗质量相关指标变化规律基本相同,种子发芽势、发芽率、发芽指数、活力指数、正常苗率及幼苗质量相关指标均随贮藏年限的增加呈降低趋势,种子浸提液电导率呈上升趋势。不同品种耐贮能力有较大差异,东农690和吉林小粒6号种子的安全贮藏期为1年;九芽豆1号耐贮性较好,安全贮藏期为2年。In order to explore the influence of low temperature storage years on seed vigor and seedling quality of Glycine gracilis,three varieties with different mature stages growth processes were used as experimental materials,and five sowing dates were set up for researching into the change regularities of the seed vigor and seedling quality of Glycine gracilis under the low temperature storage condition.The results indicated that,with the increase of storage life,quality related indicators of different varieties of Glycine gracilis changed in an approximately same regulation.The germination potential,germination rate,germination index,vigor index,normal seedling rate and seedling quality showed a decreasing trend with the increase of the storage life and the electrical conductivity of the seed extracts showed an increasing trend.It was different on storability among three different varieties.Dongnong 690 and Jilinxiaoli 6 had a safe storage period of one year,while Jiuyadou 1 had a better storability with a storage period of two years.
