摘 要 ：通过多年来对小麦冠层温度和生物学性状的观测，结果发现：自然界存在小麦温度分异现象，即不同基因型小麦具有各不相同的体温并被划分为若干类群，这些类群的生物学性状有明显差异，尤其在叶片输出功能期、根系、叶绿素含量、蛋白质氮含量、丙二醛含量、蒸腾速率和净光合速率等方面。冷型小麦在上述诸方面表现较优。因而，冠

Abstract:On the basis of observation with the canopy temperature and the biological character of wheat for many years，the difference in wheat‘s temperature has been discovered in natural world，that is，each of wheats with different genotypes has a plant temperature all its own and they have been divided in
