Cold hardiness of seedlings from open-pollinated seeds of 7 trees which differed in ripening time were tested with various methods. The injury of seedlings when exposed to low temperatures of -2 to -3[degree]C for 24 hours and negative correlation with the injury by KC103 solution. The injury by low temperature showed positive correlation with the degree of plasmolysis in CaCl2 solution, but such a correlation was not found with plasmolysis in CO(NH2)2, KNO3, KC1 + CaCl2. In general, earlier ripening strains are less resistant to coldness.
