Freezing resistance of ten cultivars of Chestnut (Castanea crcnata S. et Z.) collected from four different sites of Kyunggi Province, Korea on March 2, 1975, was measured to find out the differences among tissue parts, and those among cultivars. The freezing and thawing rates were controlled lower than 6℃/hr. which occurs in nature. The resistance to low temperature was in order from lowest to highest; winter bud, cambium, xylum ray parenchyma and bark cortex. The difference in cold hardiness among cultivars was not consistent among tissue parts of twig stem except in cultivar Dan-Taeck of which all tissue parts showed highest cold-hardiness. The importance of the study on the seasonal variation in cold hardiness of different tissue parts was discussed in terms of choosing the most cold resistant Chestnut culitivar in Korea.
