| 摘 要： | 为探明转育获得的抗除草剂不育系的抗性效应,苗期用不同浓度草甘膦处理抗草甘膦油菜不育系TA6,TA7。结果表明:随着喷药浓度增加,对叶片、茎秆和根的生长表现为不同程度的抑制作用,其中对叶片生长的影响较早且最严重,对茎秆生长的影响较迟,程度相对较轻,对根部生长的抑制作用最小,表现为先抑后扬,但随着时间推移,影响程度逐渐减轻,至喷药60 d后,油菜苗生长基本恢复正常。花期育性调查和套袋自交结果表明,抗性不育系喷施草甘膦除草剂后,育性未受任何影响,TA6,TA7的不育率和不育度均表现正常。

| Abstract: | Effects of different glyphosate concentration in glyphosate-resistant Rape TA6 and TA7 were studied.The results showed: As glyphosate concentration were enhanced,the restrain to leaf,stem and root were different.The restrain to leaf was highest and showed early.On the contrary,the restrain to stem was lowest and showed lately.Effect of different glyphosate concentration became smaller and smaller with growing stages 60 days later,there were no effects to rape.There was no influence on fertility of sterile line. |
