亚铁胁迫影响不同基因型水稻地上部养分吸收的研究
Effect of high iron stress on shoot element absorption of different genotype of rice DH population.
【摘要】 溶液培养试验表明:连续4周对水稻DH群体(Azucena×IR64)进行高铁胁迫,该群体在铁的抗性上出现高度分离,筛选出极抗铁毒基因型.铁毒极敏感基因型和中间型lines.养分测定表明:不同基因型水稻本身养分含量存在差异.高铁胁迫抑制了Ca、Mg、Zn、Mn、P的吸收,促进了Cu的吸收.高铁胁迫破坏了养分吸收的一些相关关系
【Abstract】 The objective of this study is to evaluate the relation between high iron stress and element absorption of different genotype of rice ( Oryza sativa L.) DH population (Azucena × IR64). The population has been highly segregated under iron stress. The result also shows that high iron stress restrains P, Ca, Mg, Mn and Zn absorption and enhances Cu absorption. It indicates that P, Ca, Mg, Mn, Zn, Cu content in rice shoot is closely associated with high iron stress.
