Correlation analyses of the effect of temperature before bagging and freezing tolerance as LT₅₀ ACC on seed yield per plant in 11 Arabidopsis thaliana accessions under field conditions. Seed yield per plant (g) was calculated in 2013/14, 2014/15, 2015/16, 2017/18 and 2018/19 for all accessions and plotted against the average minimum temperature at 5 cm above ground (°C) in the 2 months prior to bagging of the plants (a) and the cold-acclimated freezing tolerance of each accession (b). Data points represent five replicates for each accession and year (n = 274). Pearson correlation coefficients (r) and P values are indicated. Accessions with description as well as their respective freezing tolerance (LT₅₀ ACC) are listed in Table S1
