摘　　要：利用BAU-1型红外线测温仪测定不同小麦品种(系)不同年份的冠层温度并测定具有代表性品种(系)的叶片输出功能期、高分子量麦谷蛋白亚基累积和麦谷蛋白大聚合体(LMP)的含量、叶面积和干重,比较其关系,初步确定了我省春小麦温型划分标准。通过两年的试验结果,将晚熟组的对照品种新克旱9号划为冷型小麦,把中熟组的对照品种垦红14划为暖型小麦,这就为我们从生理育种上育成优良的品种提供了更好的参考依据。In order to rudiment confirm the warm typal standard of the spring wheat canopy temperature in Heilongjiang province, measured the export functional periods of leaves and the accumulation of high molecular weight Glutenin subunit and the content of large glutein polymer and area of leaf and dry weight of leaf, studied the relationship with BAU-1 infrared thermometer. As a result, marked Xinkehan 9 the CK in late-mature group as cold type wheat, and so marked Kenhong 14 the CK in middle-mature group as warm type wheat, thus offered well reference index for us on physiological breeding of wheat.
