1) Leaf position
叶位
1.
Variation of nicotine conversion rate among different leaf positions and leaf areas for burley tobacco of different conversion type
白肋烟不同类型转化株烟碱转化率的叶位间和叶点间变异
2.

水稻氮素及钾素叶位分布特点及诊断叶位研究
3.
involucrata leaves with different age and at different leaf position were analyzed by the method colorimetry.
结果表明:不同年龄同一生长期珙桐叶的SOD活性不同,同年龄级同层珙桐叶的SOD活性随叶位增加大致呈先升后降的变化;同叶位不同层及同层不同叶位的珙桐叶的SOD活性不同。
2) Stalk position
叶位
1.
Evaluation on flue-cured tobacco leaves quality of different stalk position with analysis of principal component and cluster;

2.
Differences in alkaloid and total nitrogen contents among air-cured leaves of different burley varieties and stalk positions;
白肋烟不同品种和叶位叶片生物碱和总氮含量的差异
3.
Greenhouse and field grown converter plants were planted to determine the difference in the conversion of nicotine to nornicotine between lamina and midrib,changes during air_curing and differences between different stalk positions.
在大田和温室栽培条件下,以白肋烟TN 90不同程度转化株为材料研究了烟叶主脉和不同叶位叶片烟碱转化率的差异及在烟叶晾制过程中的变化,结果表明,转化株烟叶在晾制后主脉的烟碱转化率远高于叶片,叶片的烟碱转化主要发生在烟叶晾制前2周的变黄阶段,叶脉的烟碱转化高峰发生在晾制的第2~3周。
