Mean LT50 and LT100 values of each Cochlearia and Ionopsidium species before (orange) and after (blue) cold acclimation. LT values were estimated by fitting a logistic function to measured PEL values (see examples in Fig. 3). Error-bars indicate the standard deviation. For I. glastifolium and I. megalospermum no standard deviation could be derived as sample size is n = 1 each.
