High density photosynthetic CO2 response curves of hybrid poplar, New York, USA, 2019

This data package contains photosynthetic CO2 response (ACi) curves of sunlit canopy leaves of species Populus deltoides Bartr. x Populus nigra L. (hybrid poplar) grown in pots at Brookhaven National Laboratory in New York, USA, throughout 2019. Attached leaves were measured using a Li-Cor 6800 gas exchange instrument. This data was collected in support of Walker et al (2020), Multi-hypothesis analysis of Farquhar and Collatz photosynthesis models reveals unexpected influence of empirical assumptions.
