Response of eco-physiological characteristics to CO2 in Stipa bungeana
Artemisia sacrorum
Stipa grandis
and Aneurolepidium dasystachys leaves was studied.Results showed that with CO2 concentration increasing
photosynthesis rate(Pn)
intercellular CO2 concentration
and water use efficiency(WUE) of the four species were increased and stomatal conductance and transpiration rate(Tr) were decreased.Photosynthesis characteristics of the four species varied with season.The order of the species
in terms of Pn and Tr
was: Stipa grandis Artemisia sacrorum Stipa bungeana Aneurolepidium dasystachys;and the order of the species
