Table 1 Cold acclimation in oat. Frost damage in non-acclimated (20°C) and acclimated (12 or 24 h at +4°C) oat spring varieties Birgitta and Matilda and winter varieties Gerald and 83-48-CH. Plants were incubated at -15°C for 3 h, 6 h and 12 h and then recovered for 1 week in the greenhouse. Frost damage was recorded on a scale from 1 to 5, where 1 represents no damage and 5 represents dead plants.
