摘要/Abstract

摘要： 利用田间微区试验,在整株水平上研究了10种小麦进化材料水分利用效率(WUE)和氮利用效率(NUE)间的关系。结果表明,小麦在从二倍体→六倍体的长期进化过程中,WUE和NUE均逐渐增加。除法国黑麦外,其余9种小麦进化材料WUE和NUE间呈显著正相关,表明法国黑麦高的NUE可能与WUE以外的其它生理机制有关。

Abstract: Afield micro -plot experiment on the interrelationship between water use efficiency and nitrogen use efficiency of different wheat evolution materials at the whole plant level showed that both water and nitrogen use efficiency increased gradually during the long evolution process from diploid to hexaploid.The water use efficiency was positively related with nitrogen use efficiency across nine evolution materials excluding French S.cereals, suggesting that the high nitrogen use efficiency of French S.cereals might be related with physiological mechanisms other than WUE.
