摘　　要：为探明昆明烤烟有机酸的状况,2014—2016年共采集样品480个,研究有机酸特征及影响因素.结果表明:1)有机酸均值为52.63 mg/g,变异系数为32.37%;2)有机酸由高到低的顺序为w(非挥发多元有机酸)>w(不饱和脂肪酸)>w(饱和脂肪酸);3)有机酸总量在产地、品种和部位间差异有统计学意义;4)5月和8—9月平均昼夜温差对苹果酸和柠檬酸影响显著;5)海拔对柠檬酸、月桂酸、肉豆蔻酸和硬脂酸影响显著.综合认为,昆明烟区的烤烟有机酸丰富,但易受产地、品种、部位、昼夜温差和海拔影响.To understand the organic acids content status of flue-cured tobacco in Kunming city, 480 samples were collected from the year 2014 to 2016 to study the characteristics and influencing factors. The result indicated that: 1) The average value of organic acids content were 52.63 mg/g and the coefficient of variation were 32.37%;2) The order of organic acids content from high to low was non-volatile organic acids, unsaturated fatty acids and saturated fatty acids;3) The total amount of organic acids content had statistical significance among origin, variety and part;4) The average day-night temperature difference in May, August and September had great influence on malic acid and citric acid;5)The influence of altitude on citric acid, lauric acid, myristic acid and stearic acid were obvious. In summary, the organic acids content of flue-cured tobacco in Kunming city were rich but susceptible to the effects of producing area, variety, part, day-night temperature difference and altitude.
