Difference Studies for the Stomatal Conductance and the Leaf Chlorophyll Concentration in Different Positions of Lilium Regale Leaves

摘要

The stomatal conductance and leaf chlorophyll concentration of Lilium regale were measured by using a chlorophyll meter (SPAD-502; Minolta, Tokyo, Japan) and the Li-6400, then the nonparametric test of the SPSS21.0 was carried out and the results were obtained as follows: (1) Differences for the stomatal conductance in different position leaves of Lilium regale were not necessarily remarkable, but dissimilarities in the stomatal conductance were conspicuous. (2) In the one hand, no apparent differences in leaf chlorophyll concentration in the upper position of Lilium regale were found in 10 plots, but marked in the middle and in the lower. In the other hand, remarkable differences can be seen in the stomatal conductance in the upper, the middle and the lower.
