胞质抗除草剂谷子发育及与敏感型常规品种的差异

Development of cytoplasmic herbicide resistance foxtail millet and its difference to the susceptible general varieties

摘要: 以对除草剂敏感的常规品种“豫谷2号”为对照，试验研究抗除草剂谷子“0971”的生长发育特点结果表明，“0971”苗期发育慢，抽穗晚，但后期发育加快，并很快与“豫谷2号”各性状相持平。由于灌浆速度慢和灌浆时间短，“0971”穗干物质量明显处于劣势。

Abstract: The development characters of cytoplasmic herbicide resistance foxtail millet“097 1”is studied taking the susceptible general variety “Yugu 2”as the control in this paper．The results show that the development of“0971”is slower than that of“Yugu 2”in early stage．the head stage is later too．But it grows faster at the later stage and most of the characters get the same level compared to “Yugu 2”．The head weight of“0971”is lighter than that of“Yugu 2”because of the later head stage and the slower milking speed．
