摘要	Both Meconopsis integrifolia Franch. and M. horrichda var. racemosa Maxim. are native to the Himalayas and prized as ornamentals and medicinal plants. Cultivating Meconopsis is difficult at lower altitudes owing to its intolerance to hot summers. To develop a cultivation strategy and predict plant performance for introduction, we compared the photosynthetic capacity of M. inlegrifolia and AI horridula as well as their photosynthetic responses to light and temperature in the nursery at an altitude of 3,260 m. Meconopsis integrifolia was more sensitive to high temperature than M. horridula while M. horridida reached a peak photosynthetic rate at a higher light level than M. integrifolia. Compared with M. integrifolia, M. horridula showed a higher light saturated photosynthetic rate, maximum RuBP saturated rate of carboxylation, light saturated rate of electron transport, stornatal conductance, leaf dry mass, and N content per unit area. The mesophyll conductance and leaf N content per unit mass of the two species were not significantly different. The differences in photosynthetic capacity between two Meconopsis species were correlated with their biochemical efficiency and leaf thickness, but not chlorophyll content or mesophyll conductance. The results suggest that, at lower altitudes, introducting and cultivating M. horridula could be easier owing to its wider physiological adaptation.
