The one year old persimmon twigs were collected to know cold tolerance at different temperatures. The selected persimmon cultivar were mast commonly growing in southern part of Korea, such as Bong-Ok, Chungdo-Bansi, Naju-Pasi and Kiwonbang growing at attached farm of Kyungpook Nat. Univ. Browning of bud was the most significant at $-15^{\circ}C$. Naju-Pasi showed no difference in damage between $-5^{\circ}C$ and $-15^{\circ}C$ so called, it is cold tolerant cultivar. Browning of the woody part showed the same tendency with the bud at $-15^{\circ}C$. Chungdo-Bansi was shown the mast weak in cold tolerance than the other cultivars. Electric conductivity was higher at $-15^{\circ}C$ in all persimmon cultivars. Naju-Pasi and Bong-Ok cultivars were weak in cold tolerance even at $-10^{\circ}C$. Bud bursting was occurred at $-15^{\circ}C$ but few on another twigs tested. Naju-Pasi was the lowest while Kiwonbang was higher in the bud bursting. From these result, Naju-Pasi and Bong-ok cultivars were lower in cold tolerance. Kiwonbang cultivar was shown cold tolerance than the other cultivars. These results can be utilized for the persimmon cultivation at different localities in future.
