Overwintering temperatures affect freezing temperatures of turions of aquatic plants

Original language description

The effect of different overwintering temperatures (2.5 1degrees C in a refrigerator or outdoor natural overwintering on wet topsoil with weak frosts) on the freezing temperature and survival rate of turions of 10 aquatic plant species with different ecological traits (free-floating habit or bottom rooting) was studied using mini thermocouples. Dormant, non-hardened turions of 9 species exhibited freezing within a narrow temperature range of -7.0 to -10.2 degrees C, while Hydrocharis froze at -3.6 degrees C. The mean freezing temperature of outdoor hardened turions of 6 species was within a very narrow range of -2.8 to -3.3 degrees C. The freezing temperatures indicate freezing of the extracellular water. The hardened turions of all 7 species were ableto survive mild winter frosts under the topsoil conditions at 76-100 % rate. Thus, the turions can be hardened by weak frosts and their frost hardiness is based on the shift from frost avoidance in non-hardened turions to frost tolerance
