Fig. 2. The effect of a 7-d deacclimation treatment (Day 21 through 28) followed by low temperature reacclimation (after Day 28) on freezing tolerance (LT50) of three oilseed rape cultivars. The deacclimation treatment was prior to vernalization saturation. LSD values represent significance at P = 0.05.

Fig. 3. The effect of a 7-d deacclimation treatment (Day 63 through 70) followed by low temperature reacclimation (after Day 70) on freezing tolerance (LT50) of three oilseed rape cultivars. The deacclimation treatment was after the vernalization requirement was met. LSD values represent significance at P = 0.05.
