摘要： 冷型小麦是一种冠层温度持续偏低的小麦，于80年代后期发现.此种类型小麦的叶片功能期较长，时间距较短，麦芒转黄速度较慢.上述表观特征和内部代谢功能有着密不可分的关系，表现在蛋白质氮含量、气孔传导、蒸腾速率、过氧化氢酶活性、丙二醛含量和净光合率等方面均较优越.根据冠层温度和表观特征可较准确地识别具有良好代谢功能的冷型小麦材料。

Abstract: Cold typal wheat is a wheat with continuous lower canopy temperature, which has been discovered in the late eighties. It has a longer leaf functional period, shorter distance between times, and slower speed with the awn′s yellowing than those of other typal wheats. The phenomenal characteristics of the wheat have close relation to the metabolic function, which is more excellent in protein nitrogen content, CS, transpiration rate, CAT activity, MDA content and net photosynthetic rate, etc. than those of other typal wheats. Cold typal wheat with good metabolic function can be distinguished more accurately according to canopy temperature and phenomenal characteristics.
