摘 要:对328份C3F等级的云烟87样品进行检测,采用多元统计方法分析烤烟石油醚提取物含量与物理性状的关系。结果表明:烤烟石油醚提取物含量与叶长和拉力关系可用三次方程模型描述,与叶宽和单叶重关系可用S型模型描述,与填充值关系可用线性模型描述,与叶质重关系可用对数模型描述,与含梗率关系可用混合模型描述,与平衡含水率关系可用逆矩阵模型描述,曲线回归方程均达到极显著水平;烤烟石油醚提取物含量与叶质重、叶长、平衡含水率和叶宽等指标呈极显著正相关关系,与填充值呈极显著负相关关系;构建了烤烟石油醚提取物含量与物理性状间多元回归方程。因此,与石油醚提取物含量关系密切的物理指标是平衡含水率、叶长、叶质重和拉力等。328 flue--cured tobacco leave samples letted to determine and analyze,the relationship for yunyan 87 varieties of C3F grades were se between tobacco petroleum ether extract content and the physical properties was analyzed using multivariate statistical methods. The results showed that the relationship among petroleum ether extract content and leaf length and tobacco pulling force could be described by cubic equation model. Besides,the relationship among petroleum ether extract content and leaf width and weight per leaf could be described by S type model. Mo- reover,the relationships among petroleum ether extract content and filling capacity, per leaf area weight,tobacco stem ratio and tobacco equilibrium moisture content could be described by linear model,logarithmic model, compound model and inverse model respectively. And all above model equations were significant at 1% level. The petroleum ether extract content and per leaf area weight, leaf length, equilibrium moisture content and leaf width and indicators are significantly positive correlation, and filling capacity in rechargeable significant negative correlation;Furthermore, we constructed the multiple regression equation between petroleum ether extract content and physical properties. Therefore,the physical indexs which were closely related with tobacco petroleum ether extract content are equilibrium moisture content, leaf length, leaf weight and tobacco pulling force, etc.
