摘要	Despite extensive studies on effects of elevated CO2 concentration ([CO2](e)) on plant growth, few studies have investigated the responses of native grassland plant species to [CO2](e) in terms of nutrient acquisition. The effects of [CO2](e) (769 +/- 23 ppm) on Artemisia frigida and Stipa krylovii, two dominant species in Inner Mongolia steppe were investigated by growing them for 7 weeks in Open-Top Chambers (OTC). Exposure to [CO2](e) enhanced shoot and root growth of A. frigida and S. krylovii. Elevated [CO2] increased photosynthetic rates (Pn) by 34 % in A. frigida but decreased Pn by 52 % in S. krylovii. Moreover, root-secreted acid phosphatase activity in A. frigida was stimulated by [CO2](e), while exudation of malate from roots of S. krylovii was suppressed by [CO2](e). Exposure to [CO2](e) led to a decrease in P concentration in shoots and roots of A. frigida and S. krylovii, but total amount of P accumulated in shoots and roots of both species was increased by [CO2](e.) The two dominant species in temperate steppes differed in their responses to [CO2](e), such that A. frigida was more adapted to [CO2](e) than S. krylovii under low availability of soil P.
