摘　　要：以云南保山隆阳烟区不同海拔高度气温和降水量数据及烤烟品种K326和云烟85烟叶为材料,研究了不同海拔高度气象因素对烟叶物理特性的影响。结果表明,保山隆阳烟区不同海拔高度的旬最高气温和温差变化幅度较大;海拔高度大于1800m的烟区温差变化小于海拔高度低于1800m的烟区。烟叶含梗率、叶宽除受气象因素影响外,还与不同品种对环境因素变化的敏感性不同有关;烟叶的厚度和密度则主要受气象因素的影响,不受烤烟品种的种质特性影响。烤烟品种K326对环境因素变化较为敏感,并且烟叶物理特性变化在海拔高度1800m左右出现明显变化,而云烟85对海拔高度气象因素的变化敏感性相对较低。The effects of meteorological factors at different altitudes on the physical characteristics of flue-cured tobacco were investigated using the data of temperature at different altitudes and rainfall in Longyang tobacco planting area of Yunnan and the tobacco leaf of K326 and Y85 as experimental materials.The results indicated that the tobacco-growing areas in Longyang district of Baoshan had a larger variation range of maximum monthly temperature at different altitudes and temperature difference,and the change of temperature difference at tobacco-growing areas over 1800 meters was smaller than that at tobacco-growing areas below 1800 meters.The stem percentage in tobacco leaf and the blade width were affected by meteorological factors and different sensitivities of different cultivars to changes of environmental factors,but the thickness and density of tobacco lea were mainly affected by meteorological factors.K326 is more sensitive to change of environmental factors,and the physical characteristics of its leaf had an obvious change at the altitude around 1800 meters;but the sensitivity of Y85 to the changes of meteorological factors and altitudes was relatively low.
