Maintenance of leaf N controls the photosynthetic CO2 response of grassland species exposed to 9 years of free-air CO2 enrichment

Crous, Kristine; Reich, Peter B; Hunter, Mark D; Ellsworth, David S

Description

Determining underlying physiological patterns governing plant productivity and diversity in grasslands are critical to evaluate species responses to future environmental conditions of elevated CO2 and nitrogen (N) deposition. In a 9-year experiment, N was added to monocultures of seven C3 grassland species exposed to elevated atmospheric CO2 (560 μmol CO2 mol-1) to evaluate how N addition affects CO2 responsiveness in species of contrasting functional groups. Functional groups differed in their...[Show more]
