| 摘 要： | 利用盆栽试验研究了不同生育时期干旱胁迫对小麦产量及产量因素的影响。试验表明 ,小麦孕穗期和抽穗期干旱对产量的影响最大 ,与对照相比 ,皖麦 38和皖麦 19分别减产 6 1.95 %、6 0 .89%和 43 .35 %、43 .2 1%。蜡熟期的干旱胁迫对小麦有增产效应 ,2个品种分别比对照增产 7.40 %和 11.34%。

| Abstract: | The effects of drought stress in different development stages on wheat yield and yield components were studied with the method of outdoor pot cultivation experiment. The results showed that the maximum influence of drought stress on wheat yield was in wheat booting stage and head sprout stage.The output of wheat variety-Wanmai 38 and Wanmai 19 was decreased by 61.95%,60.89% and 43.35%, 43.21% in the two stages respectively, compared with CK. The water stress in physiological maturity period had an effect on increasing wheat grain yield and the grain yield of Wanmai 38 and Wanmai 19 was increased by 7.40% and 11.34% respectively. |
