文山烟叶主要化学成分与海拔经纬度相关性分析

Correlation Analysis between Chemical Compositions of Flue-cured Tobacco Leaves and Altitude,Longitude and Latitude in Wenshan

采用简单相关和典型相关分析方法研究了文山州烤烟化学成分与海拔和经纬度之间的相关性,结果表明:文山州海拔、经纬度对烟叶主要化学成分的影响依次为海拔>经度>纬度;烟叶总糖和还原糖含量与海拔存在极显著负相关关系,与经度存在极显著正相关关系;烟叶烟碱和总氮含量与海拔呈极显著正相关,与经度呈极显著负相关;B2F和X2F烟叶钾含量与海拔存在显著正相关关系,B2F烟叶钾含量与经度存在显著负相关关系。

The correlations between altitude, longitude, latitude and the contents of chemical components in flue-cured tobacco in Wenshan were analyzed with simple correlation analysis and canonical correlation analysis. The results indicated that the influence on the main chemical composition of flue-cured tobacco in Wenshan turn for altitude〉longitude 〉 latitude. There were extremely significantly negative correlation between altitude and the contents of total sugar, reducing sugar, and there were extremely significantly positive correlation between longitude and the contents of total sugar and reducing sugar. There were extremely significant positive correlation between altitude and the contents of total N, nicotine, and there were extremely significant negative correlation between longitude and the contents of total N and nicotine. There were extremely significantly positive correlation between altitude and the contents of K of B2F and X2F, and there were extremely significant negative correlation between longitude and the contents of K of B2E .
