Analysis of Difference in Physical Characteristics of Leaves of Different Flue-cured Tobacco Varieties

Through the plot experiment with a number of localities,we studied the difference in the physical characteristics of flue-cured tobacco leaves of five varieties.The results showed that Nanjiang No.3 had significantly higher single-leaf weight of middle leaf and lower leaf than other varieties,and it also possessed significantly higher leaf specific weight of upper leaf than other varieties,while there were no significant differences in single-leaf weight and leaf specific weight of different positions of leaves among other varieties.K326 had the highest leaf-stalk rate,and the narrowest leaf width.Among 5 varieties,there were significant differences in leaf length,leaf width and length-width ratio of different positions of leaves except the middle leaf length.
