| 摘 要： | 在2004～2005小麦生长季,以强筋小麦济麦20为试验材料.研究了不灌水(WO)、底墒水+拔节水+开花水(W1)、底墒水+冬水+拔节水+开花水(W2)、底墒水+冬水+拔节水+开花水+灌浆水(W3)4个灌水处理条件下小麦子粒淀粉组成及产量和水分利用率的变化.结果表明,开花后WO处理的旗叶光合速率和子粒直链淀粉含量显著低于浇水处理:灌浆中后期,浇水处理旗叶的光合速率和子粒直链淀粉含量为W3W2、W1.W0处理子粒支链淀粉和总淀粉含量显著高于W1、W2、W3处理,开花后21 d至成熟期,浇水处理间为W1、W2W3.子粒产量为W1、W2W3W0、W1、W2之间无显著差异,表明浇冬水对子粒产量无显著影响,灌浆水降低子粒产量.水分利用率为W0W1W2W3,水分生产效率W1W2W3,直链淀粉和支链淀粉含量的比值为W0

| Abstract: | This research was carried out from 2004 to 2005,using a strong wheat cultivar,namely Jimai 20.The aim was to study how the starch components,grain yield and water use efficiency(WUE) changed under different water irrigation stage and rate.The results were as follows.After anthesis,the photosynthetic rate of flag leaves and amylase content in grain of the treatment W0 were significantly lower than those of other treatments(W1,W2,W3);in the middle of grain filling stage,the photosynthetic rate of flag leaves ... |
