In order to provide the theoretical basis for introduction and cultivation,we compared the leaf anatomical structure,photosynthetic characteristics of Agastache rugosa from different areas.The results showed that:(1)the leaf palisade tissue compose of a long columnar cell,and the leaf spongy tissue with 4-6 layers,the lower epidermis has more stomata and non-glandular hairs,leaf stomata shape were mostly oval of A.rugosa from different areas.The A.rugosa from Chengdu had the largest stoma diameter,greatest stoma density,and the longest non-glandular,the chlorophyll contents were also significantly higher than other eares;(2)the light saturation point (LSP) and light compensation point(LCP) of A.rugosa from different areas between 688.67-1 244.56 and 19.42-73.62 μmol·m^-2·s^-1,apparent quantum yield (AQY) of A.rugosa from Shangqiu was the highest;(3)the diurnal variation of net photosynthetic rate (P_n) of different areas A.rugosa were both bimodal curves,which appeared peak at 10:00 and 16:00.And an obvious midday depression of photosynthesis appeared at 14:00,and the photosynthesis siesta influenced mostly by stomatal limitation factor.Research showed that:among the five A.rugosa areas,the leaf structure existed significance differences,In some areas,there was a correlation between the leaf morphology and the light response characteristics.In addition,A.rugosa cultivated in Sichuan showed a better ability to adapt to the light environment and photosynthetic capacity,can be introduced as a local priority object.
