摘要
以适熟期烟株中部叶为材料,研究了K326,红大,NC82,云烟85,云烟87和中烟201等烤烟品种烟叶的结构和输导系统的差异.结果表明,不同品种烟叶叶形与比叶面积差异显著,而叶面积和叶片厚度差异不显著;不同烤烟品种各级叶脉干重质量分数差异显著,中烟201和红大品种的主脉和一级侧脉所占比例明显大于其他供试品种.
Differences in leaf structure and conductive system of different flue-cure tobacco varieties were investigated using proper mature leaves in middle plant shoot as material. The results indicated that there were significant differences in leaf shape as well as specific leaf area and mass fraction of different kinds of leaf veins, while there were little differences in leaf area and thickness; both the mass fractions of primary veins and secondary veins of Zhongyan 201 and Hongda were higher than that of others.
