【摘要】 本研究以小麦为试材,在不同水浸时间后,用Na（?）理M₁代和M₂代,观察其生理损伤和M₂代突变情况.结果表明NaN₃是一种高效诱变剂.国外有的学者认为NaN₃处理水,浸过的种子突变频率高,但本实验以NaN₃10^-3M,浸种风干种子2小时突变频率最高.故用NaN₃诱变小麦可直接处理干种子,既方便,效果又好.更多还原

【Abstract】 This study dealt with the effect of NaN3 on the physielogical damage of M1 and the mutation frequency of M2, when the wheat seeds were pre-soaked in water for different length of time.NaN3 was an effective chemical mutagen. Some scientists from a broad believed that the highest mutation frequency was obtained when the pre-soaked wheat seeds were treated with NaN3. But in this study, the mutation frequency was the highest when the dry wheat seeds were treated with NaN3（10-3M, 2 hr. ） . So it was very effective, and convenient to treat dry wheat seeds with NaN₃.更多还原
