凉山烤烟钾含量及其与有机酸关系的分析

S572.01; 以四川凉山10个烟叶主产区64份烤烟C3F等级烟叶为样品,采用最优曲线回归拟合和灰色关联度分析方法,研究了凉山烤烟钾含量状况及其与有机酸含量的关系.结果表明:凉山烤烟叶片钾含量平均值为1.84%,整体钾含量偏低;烟叶钾含量与乙二酸、丙二酸、苹果酸、十七酸含量的回归方程决定系数均达到了显著水平,且均表现为烟叶钾含量越高,以上有机酸含量就越高;烟叶钾含量与非挥发性有机酸含量间的关系最为密切....

In order to explore the relationship between the potassium content and organic acids content of flue-cured tobacco leaves in Liangshan,64 samples of C3F grade flue-cured tobacco were collected from 10 tobacco-planting areas.By means of optimum curve simulation and grey correlation analysis,the relationship was explored.The results were as follows:(1)The general potassium content of flue-cured tobacco leaves was low with the average of 1.84%.(2)The R2 of regression equations between the potassium content and oxalic acid,malonic acid,malic acid,seventeen acid reached significant level,and the potassium content had positive correlation with the content of the above organic acids.The potassium content had most closely relationship with non-volatile organic acid content.
