烤烟烟碱含量与其他化学成分的相关关系及其阈值的研究

Study on the threshold of nicotine content and correlations between nicotine and other chemical components in flue-cured tobacco

本文采用数理统计的方法,系统分析了烤烟烟叶中烟碱含量与总氮、总糖的相关关系。研究表明烤烟烟叶中烟碱含量存在明显的阈值;以烟碱阈值为界,烤烟烟叶中烟碱含量与总氮、总糖的含量存在两种相反的相关关系,当烟碱含量大于阈值时,烟碱与总氮呈正相关关系,与总糖呈负相关关系,当烟碱含量小于阈值时,烟碱与总氮呈负相关关系,与总糖呈正相关关系。

Correlations between nicotine content and the content of total nitrogen, total sugar, and potassium in flue-cured to bacco were systematically analyzed by means of mathematical statistics. Results indicated that in flue-cured tobacco leaf there was a threshold of nicotine content, above which the nicotine content was positively correlative to the content of total nitrogen and negatively to that of total sugar and potassium, while below which the nicotine content was negatively correlative to the content of total nitrogen and positively to that of total sugar and potassium.
