| 摘 要： | 在二种水分处理下,对16个冬小麦品种的水分利用效率及其生理影响因子进行了分析,结果表明,品种间水分利用效率存在显著差异,不同冬小麦品种与水分利用相关的因子存在一定差异,其中,水分利用效率与产量和收获指数呈显著正相关,品种水分利用效率与其开花时间和旗叶比叶重有一定的正相关关系,品种间水分利用效率与单个生理因子间相关性达不到显著水平。

| Abstract: | s: WUE and the interrelated factors of 16 varieties of winter wheat were conducted under two irrigation model, the results showed WUE and the influencing factors of different varieties were greatly different. Significantly positive correlation is confirmed between WUE and yield, harvest index, the results also show that there is a positive correlation between WUE and flowering date, area per gram of flag leaf, but the coefficients between conducted physiological factors and WUE are very low. |
