Abstract:

There was heterogeneous distribution in stomatal conductance（gs）and stomatal aperture for both high and low light leaves of Ligustrum sinense Lour. in four designated positions within a leaf. Linear or exponential or polynomial relationships between gs and stomatal aperture were found when regression of gs and stomatal aperture was established. Statistical analysis revealed that the relationship between gs and stomatal aperture for high light leaves was more significant than that of low light leaves. A linear relationship between gs and stomatal aperture existed in both positions 1 and 3 for both high and low light leaves. The stomatal density of the low light leaves was much lower than that of the high light leaves. The sensitivity of stomata to changing environment for high light leaves was higher than that for low light leaves, which may also relate to the higher stomatal density for the high light leaves.
