| 摘 要： | 以一整套"中国春"背景的单染色体代换系和受体"中国春"、供体"Synthetic 6x"为材料,研究了水培条件下磷胁迫对小麦苗期磷素吸收和利用能力的变化.结果表明,低磷条件下,"Synthetic 6x"比中国春在磷胁迫下有较高的磷吸收能力,较之供体"Synthetic 6x"和受体"中国春",各代换系的单株磷累积能力...

| Abstract: | Using a complete set of chromosome substitution lines(CSLs) in Chinese Spring(CS) genetic background,Chinese Spring,and chromosome donor Synthetic 6x as the experimental materials,the effects of chromosome substitution on phosphorus acquisition capacities in wheat seedling stage under Pi-stressed condition were analyzed under hydropinically growth condition.Under the Pi-stress condition,the accumulative P amount per plant in Synthetic 6x is more significantly increased than in CS.The accumulative P amount p... |
