摘要：

采用SRI值法，考察了不同等级烤烟烟叶抗破碎性能与烟叶温湿度、常规化学成分之间的关系以及分切段烤烟烟叶抗破碎性能的差异。结果表明：（1）烤烟烟叶含水率从8%增加至26%，烤烟烟叶抗破碎指数(SRI值)增加50%左右，其中中部、上部烤烟烟叶含水率在20%左右SRI值出现拐点，下部烤烟烟叶含水率在22%左右抗SRI值出现拐点，烤烟烟叶温度从20℃增加至90℃，烤烟烟叶SRI增加10%左右，且烤烟烟叶在60-70℃抗破碎性能较佳；（2）不同等级烤烟烟叶SRI值不同，抗破碎性能中部烤烟烟叶＞上部烤烟烟叶＞下部烤烟烟叶，高等级烤烟烟叶抗破碎性性能高于低等级烤烟烟叶，分切段烟叶抗破碎性能叶尖部分＞中间部分＞叶基部分；（3）常规化学成分均与SRI值呈正相关，还原糖、钾、总糖与SRI值的相关系数较大（高度相关或中度相关），还原糖、钾、总糖适当提高，有利于烤烟烟叶抗破碎性的提高。

Abstract:

This paper adopts shatter resistance index not only to investigate the relationship between different grades of smash-resistant property and temperature, moisture content, conventional chemical composition of tobacco, but also assess the divergence of flue-cured tobacco segmentation smash-resistant performance.The result indicates that (1) If tobacco moisture content increase from 8% to 26%, tobacco shatter resistance index (SRI value) will elevate by 50%, of which the middle and upper part moisture content experienced inflection with 20%, while the lower part had a slightly higher proportion, 22%. With the temperature rise from 20℃ to 90℃, the SRI value increase by 10%. The test also suggests that between 60℃ and 70℃ tobacco acquire best smash-resistant performance. (2)Smash-resistant performances descend from higher level tobacco to lower level. While middle part tobacco has the best smash-resistant performance, upper part tobacco positioned second and lower part remain the last, flue-cured tobacco leaves segmentation's strongest part lies within leaf apex, leaf middle and leaf base follow behind accordingly. (3) General chemistry components are positively correlated with the SRI values, the correlation coefficient is relatively larger between reduced sugar, potassium, total sugar and SRI value(highly or moderate relevance), and it is sufficient to improve the tobacco smash-resistant performance by increasing the proportion of reduced sugar, potassium and total sugar.
