Cold‐deacclimation of Oilseed Rape (Brassica napus var. oleifera) in Response to Fluctuating Temperatures and Photoperiod

Cold deacclimation in oilseed rape

Freezing tolerance is affected by fluctuating temperatures during winter, progress of vernalization and daylength. Rapacz (pp. 543-549) shows that cold deacclimation is faster and partly irreversible when high day-temperature, lack of vernalization requirement or long days trigger an increase in elongation rate. If not, deacclimation is irreversible and its rate depends on the mean temperature.
