| 摘 要： | 采用盆栽试验研究了水分胁迫对冬小麦水分生理特性和产量的影响。结果表明,光合速率、蒸腾速率、耗水量、耗水系数、地上部生物量、根系生物量、总生物量、穗数、千粒重和穗粒数均随土壤水分的减少而呈降低趋势;水分利用效率则呈增加趋势。通过统计回归,获得了冬小麦主要水分生理指标与土壤水分关系的数学拟合模型。

| Abstract: | The water physiology and three components of yield of winter wheat under water stress were studied using pot experiment.The results showed that photosynthetic rate,transpiration rate,water-consumption,water use coefficiency,above ground biomass,root biomass,total biomass,number of ears,1 000-grain weight and number of grains per ear were decreased with soil water drop,however,water use efficiency were increased with soil water drop.The regression model between water physiology of winter wheat and soil water content was fit out. |
