The results showed that Photosynthetic rate (Pn), Transpiration rate (Tr), stomatal conductance (Gs), NPQ and Fv/Fm of 5 years old M. officinalis were higher than that of 1 year old M. officinalis. The 5 years old M. officinalis was thought to be a better suitable for wider living site after comparative analyzing both the photosynthetic and fluorescence parameters.} }
