Light response curves of q_O for Eutrema accessions and Arabidopsis developed under three different growth regimes. Non-acclimated and cold acclimated plants of Yukon (Yu), Shandong (Sh) and Arabidopsis (At) subjected to their respective growth temperatures (A–C) as well as reciprocal temperature measurements (D–F). No results were obtained for the Yukon accession in the non-acclimated Arabidopsis regime due to poor growth. Values represent means ± SE (n = 3 to 6). CACM = cold acclimated cold measured; CAWM = cold acclimated warm-measured; NACM = non-acclimated cold measured; NAWM = non-acclimated warm-measured; q_O = coefficient of basal fluorescence quenching; SE = standard error.
