摘　　要：分析了我国742份烤烟样品的糖碱比在不同产区、不同品种、不同等级间的分布特点。结果表明：我国烤烟烟叶的糖碱比在样品间存在广泛的变异，变幅为2．47～31．77，平均值为10．45，变异系数为45．31％。我国烤烟主产烟区糖碱比在6～10区间内的样品占样品总数的39．30％。黑龙江烟叶样品糖碱比较高达16．18，陕西、重庆烟叶样品糖碱比较低，分别为5．81和7．18。糖碱比最高的品种为龙江911，平均值为16．88，糖碱比最低的品种是NC89，为8．51。不同等级烟叶糖碱比高低表现为X2F〉C3F〉C2F〉B2F。烟叶糖碱比在产区、品种和等级间均存在着显著差异。相关分析表明，烟叶糖碱比与其他主要化学成分的相关关系因产区和等级不同而存在显著差异。742 samples were analyzed to investigate the distribution of sugar/nicotine ratio in flue-cured tobacco leaves among different areas, varieties and grades. The results indicated that： sugar/nicotine ratio in the samples ranged widely from 2.47 to 31.77 with the average value of 10.45 and variation coefficient of 45.31%. The samples with sugar/nicotine ratio in the range of 6 to 10 accounted for 39.30% of the total samples. The sugar/nicotine ratio of Heilongjiang tobacco leaves reached 16.18, while that of Shaanxi and Chongqing was 5.81 and 7.18, respectively. With the average value of 16.88, the sugar/nicotine ratio of cv. Longjiang 911 was the highest; while the sugar/nicotine ratio of NC89 was the lowest with the average value of 8.51. The grades in the order of sugar/nicotine ratio were X2F〉C3F〉C2F〉B2F. There was significant different among leaves of different areas, varieties and grades. Correlation analysis showed that the correlation between sugar/nicotine ratio and other main chemical components in tobacco differed significantly among growing areas and grades.
