摘要： 冬小麦小花发育的不同时期遇到土壤干旱,对小花总数没有明显影响。但各处理间在成花数和结实数上的差异十分显著,以小花两极分化期缺水,对成花数下降影响最大;小花分化期缺水,穗粒数减少最多。除土壤水分不足直接地影响成花与结实外,还由于缺水阻碍了植株对氮、磷的吸收。各处理在缺水期间茎鞘中的硝态氮、氨基酸、全氮和无机
Abstract: Experiments on soil water stress at different developing stage ofwinter wheat floret showed that there was no siginificant effect on thetotal number of florets,however,it increased the number of degenerat-ed florets and spikelets,especially in the polarized differentiation stageand differentiation s
