摘　　要：为研究小粒咖啡对不同海拔的光合生理响应,以Catimor CIFC 7963(F6)为试验材料,分别测定了海拔730、917、1064、1285、1489 m这5个种植区的咖啡叶片的光合参数。结果表明:小粒咖啡叶片的光合参数在不同海拔下存在较大差异。不同海拔高度的大气温度、叶片温度和光合有效辐射变化趋势基本一致,即都是先升后降的单峰型,不同之处在于温度升高后再降低的时间点不同。In order to study the effects of different altitudes on photosynthetic physiology of Coffea arabica,the Catimor CIFC 7963(F6) was used as the test material,and the photosynthetic parameters of coffee leaves were measured in five planting areas with altitudes of 730 m,917 m,1064 m,1285 m and 1489 m.The results showed that there were great differences in photosynthetic parameters of C.arabica leaves at different altitudes.The variation trends of atmospheric temperature,leaf temperature and photosynthetic effective radiation of coffee leaves were basically the same at different altitudes,that is,they all rose first and then fell.The difference was that the temperature increased and then decreased at different time points.
