【摘要】 黑河3号和黑河5号大豆种子经吸湿—回干处理后,活力明显提高。回干后的种子具有明显的抗吸胀冷害的效果,经低温吸胀后,其种子比对照种子的萌发率提高1.6倍,电导率及K~+/Na~+明显降低。更多还原

【Abstract】 Two soybean cultivars, Heihe No. 3 and No, 5 were used to treat with hydration-dehydration, Results of series of experiments were obtained; The vigor of treated seeds were obviously higher, and the ability of resistance to imbibitional chilling injury was improved. The germination rate of treated seeds were 1. 6 times than control through imbibition in low temperature. The electrical conductivity of treated seeds was lower than control, and its K +/Na+ ratio was lower also.更多还原
