| 摘 要： | 选择河南中北部地区20世纪50年代以来的7个不同年代主栽冬小麦品种,在田间研究了水分对冬小麦品种干物质积累和转运、产量和水分利用效率的影响。结果表明,在冬小麦拔节和灌浆初期灌水可以明显增加干物质总量以及向营养器官的分配比例,可以增加花前营养器官贮藏的同化物向籽粒的转运量,为获得高产奠定了生理基础。在品种更替过程中,冬小麦的穗数与穗粒数无明显变化趋势,但千粒质量、收获指数、籽粒产量和WUE总体呈增加趋势。20世纪90年代以后的冬小麦品种花期前后贮藏的干物质总量大,对籽粒贡献率高,是现代品种高产的重要基础。 |

| Abstract: | Seven representative winter wheat cultivars of different decades in central north Henan were selected to study the effects of irrigation on dry matter accumulation,translocation,yield and WUE under two irrigation treatments(W0:no irrigation after returning green stage,W1:two irrigations at jointing and milky stage respectively).The results showed that irrigation increased dry accumulation and distribution at vegetative organs of winter wheat,and improved photo assimilates translocation of vegetative organs before flowering and the contribution rates to kernels.There had no obvious trend on spike number and kernel number in cultivars succession.Per 1000 kernels,harvest index,yield and WUE showed the increasing trend.Winter wheat cultivars after 1990s had more photo assimilates translocation and distribution into the kernels after flowering and it was the basis of high yield. |
| Keywords: | winter wheat different eras dry matter accumulation and translocation grain yield WUE |
