不同基因型白肋烟致香物质含量的比较

Content Contrasts of Aroma Constituents in Different Genotypes Burley Tobacco

在同一条件下对湖北省主推的5个不同基因型白肋烟品种调制后烟叶的致香物质含量进行了比较分析。结果表明,不同基因型、不同部位的白肋烟烟叶中致香物质的含量有较大差异;上部叶致香物质含量由高到低排列依次为鄂烟6号、鄂烟211、鄂烟209、鄂烟1号、22083,中部叶致香物质含量由高到低排列依次为鄂烟6号、22083、鄂烟209、鄂烟211、鄂烟1号;同一基因型白肋烟上部叶致香物质含量要高于中部叶,在相同栽培条件下,白肋烟品种鄂烟6号的总体致香物质含量最高。

In the paper, contrast was made under the same conditions on the content of aroma constituents between five different genotypes burley tobacco leaves, all from Hubei province. Results showed the total content of aroma constituents have differences in different genotypes and in different parts ofburley tobacco leaves. Content of aroma constituents in upper leaves from high to low was Eyan 6, Eyan 211, Eyan 209, Eyan 1, 22083. That of in middle leaves from high to low was Eyan 6, 22083, Eyan 209, Eyan 211, Eyan l. Content of aroma constituents in upper leaves was higher than middle in the same genotype hurley tobacco. Under the same cultivation, the highest overall content of aroma constituents was Eyan 6.
