But some significant differences exist among the three in the aspects of types of stomatic apparatus mesophyll composition and primary vein structure.

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.

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.
