| 摘 要： | 通过对13个冬小麦品种拔节期的冠层温度、产量、千粒重、抗旱指数及其关系研究得出,产量与拔节期冠层温度表现出负相关趋势,而千粒重与冠层温度表现出正相关趋势,且灌水处理的拔节期冠层温度对产量及千粒重的影响要大于不灌水处理,拔节期冠层温度对千粒重的影响显著于对产量的影响。安丰88、石05-7494对水分的敏感性较差,抗旱性较好,产量较高,只是前者拔节期冠层温度高,后者拔节期冠层温度低,适合干旱地区栽种。

| Abstract: | The results that yield represents negative correlation with canopy temperature at jointing stage,while 1000-grain weight positive correlation with that can be concluded through the study on canopy temperature,yield,1000-grain weight,drought resistance index and their relationship of thirteen winter wheat varieties at jointing stage.The effect of canopy temperature to yield and 1000-grain weight of irrigation is bigger than that of no-irrigation.And the canopy temperature at jointing stage influences 1000-gr... |
