Abstract: The 1 year and 5 years old M. officinalis cultivated in Linfeng Village Beichuan county were detected using the Li-6400XT and PAM-2500 in a sunny day. 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.
