四川烟叶淀粉含量的分析评价

对四川不同产区、品种及部位的烟叶样品淀粉含量进行了分析评价.结果表明:四川省烤烟烟叶淀粉平均含量为4.30％,但仍有近1/3的烟叶淀粉含量大于5％.相同年份不同产区、品种和部位间烟叶淀粉含量差异较大,中部烟叶淀粉含量高于其他部位,攀枝花产区烟叶的淀粉含量高于四川其他产区,云烟97烟叶淀粉含量高于其他品种.

Analysis and Evaluation of Starch Content in Sichuan Tobacco Leaves

The starch contents in tobacco leaves from different stalk positions of various clutivars grown in different areas in Sichuan were determined.The results indicated that the average starch content in Sichuan flue-cured tobacco leaves was 4.3%,however,near one-third of the samples possessed a higher starch content of more than 5%.The starch contents in leaves of various cultivars from different stalk positions and areas in the same growing year were obviously different.The starch contents in middle leaves,in leaves from Panzhihua areas,and in Yunyan 97 flue-cured tobacco leaves were higher than those in leaves from other stalk positions,leaves from other areas in Sichuan,and leaves of other cultivars,respectively.
