摘　　要：为获得具有优良直播特性的种质,以俄罗斯引进的10份水稻资源为材料,研究中胚轴长度、低温发芽能力和淹水条件下发芽率等与水稻直播相关的特性。结果表明:‘LIDER’‘、ATLANT’和‘OLIMP’低温条件下萌发速度最快,‘LIDER’、‘OLIMP’、‘ATLANT’、‘NATASHA’、‘ISTOK’和‘PARTNER’具有较好的低温发芽能力;‘ATLANT’、‘ISTOK’、‘RAPANZ’、‘GAMMA’、‘OLIMP’和‘SONET’的中胚轴长度与‘绿香粳28’在5%水平上达显著差异;在缺氧条件下,所有的品种间的发芽率均达极显著差异,但俄罗斯品种均优于对照。在所有引进的俄罗斯10品种中,‘ATLANT’与直播相关的综合性状最为突出,中胚轴长度、低温发芽能力和淹水条件下发芽率均极显著优于对照品种。In order to obtain germplasm resources with excellent direct seeding characteristics,10 rice germplasms introduced from Russia were used to study the characteristics of mesocotyl elongation length,germination capacity at low temperature and germination ability under submerging.The results showed that the germination rate of‘LIDER’,‘ATLANT’,‘OLIMP’was the fastest,and‘LIDER’,‘OLIMP’,‘ATLANT’,‘NATASHA’,‘ISTOK’and‘PARTNER’had better germination ability under low temperature condition.The mesocotyl elongation length of‘ATLANT’,‘ISTOK’,‘RAPANZ’,‘GAMMA’,‘OLIMP’and‘SONET’was significantly different from‘Luxianggen 28’at 5%level.Under anoxic condition,there were significant differences of germination ability under submerging among all varieties.All varieties introduced from Russia exhibited better germination rate than the control.Among the 10 Russian varieties,‘ATLANT’had the best comprehensive traits related to direct seeding.The mesocotyl elongation length,germination capacity at low temperature and germination ability under submerging of‘ATLANT’were significantly better than the control.
