| Summary: | The maximum carboxylation efficiency of Rubisco (Vc,max) fitted from CO2 response curves and estimated from light-saturated photosynthesis using the one-point method. Data were collected in Barrow and New York in 2018 on 6 species - Arctagrostis latifolia, Helianthus annuus, Populus canadensis, Phaseolus vulgaris, Quercus coccinea, Raphanus sativus. These data were used to compare fitted with estimated values of Vc,max to test the efficacy of the one-point method. Arctic data were used alongside temperate data for an evaluation of one-point gas exchange methodology, supported in part by NGEE Arctic. |
