通过大田试验，研究了烤烟品种（ Nicotiana tobacum L．）毕纳1号在毕节地区3个生态区烤烟不同生育期的多酚类化合物的动态变化规律，探索了不同生态条件对烤烟的物质成分积累的影响。结果表明，毕节地区烤烟酚类化合物含量较高，烤烟在整个生育期内，5种酚类化合物均呈现逐步上升的趋势，一般在成熟期前后增幅较大。不同生态区烤烟中，酚类化合物含量高低均为金沙县＞威宁县＞大方县，不同酚类物质含量的大小为绿原酸＞芸香苷＞4-O-咖啡尼奎酸＞新绿原酸＞莨菪亭，其中绿原酸和芸香苷的含量占多酚总量的79％以上，是多酚中重要的组成成分。不同生态区随着海拔高度的升高，气候条件有显著差别，对烤烟中酚类化合物的形成和积累有很大的影响。

Through field experiments , the author studied the dynamic changes of polyphenols content in flue -cured tobacco (Nicotiana tobacum L.) variety Bina No.1 at different growth stages in 3 ecological regions of Bijie, and explored the impacts of different ecological conditions on the composition accumulation of flue -cured tobacco .The results showed that:in Bijie ecological tobacco area, Bina No.1 had a high content of phenolic compounds , and five kinds of phenolic compounds contents all showed a gradual upward trend in whole growth period , especially around maturing period .For flue-cured tobacco in different ecological re-gions, the content of phenolic compounds had the following order:Jinsha county >Weining county >Dafang county.The content of different kinds of polyphenols showed the following sequence :chlorogenic acid >rutin >4-O-coffee nique acid >new chlo-rogenic acid >scopoletin, and chlorogenic acid and rutin contents accounted for more than 79%of the total polyphenols content .In different ecological regions , as the altitude increased , the climatic conditions changed obviously , and they had a great impact on the formation and accumulation of phenolic compounds in flue -cured tobacco .
