2、析表明,B2F烟叶物理特性在不同品种间差异较C3F更突出,其中以填充值和厚度最为明显。红大形态物理指标与云烟87存在较大差异,其质量物理特性指标与NC297差异显著;NC297具有较高的机械强度特性;K326的物理特性同其他品种均较为接近。遗传基础狭窄使得不同品种烤烟初烤烟叶物理特性趋于一致,滇中烟区红大品种特色较突出关键词:初烤烟叶;品种差异性;物理特性;机械强度中图分类号:$572文献标志码:A文章编号:1004—3268(2014)04—0043—05StudyonDifferencesofPhysicalPropertiesforFlue——curedTobaccoVarietie
