○ 본 연구는 기후변화에 따른 과수의 저온요구도 실태조사 및 영향·취약성 평가를 위하여 수행함
○ 본 연구 결과 전국에서 2080년 이후 저온요구도 충족이 급격히 감소할 것으로 전망되며, 경남 남해안을 중심으로 1000CU를 충족하지 못하는 지역이 발생하여 온대고수의 재배가 불량해질 것으로 전망됨

□ Purpose&Contents
This study was conducted to establish the criteria for evaluation of chilling requirement in fruit trees. Also we evaluated for impact assessment to chilling requirement of fruit trees due to climate change. This study was conducted to develop a model for evaluation the chilling requirementfor fruit trees and to survey on the chilling requirement in the northern, central and southern region of Korea.

□ Results
○ Establishment of criteria for evaluation the dormancy period of temperate fruit trees in Korea.
- The concentrations of soluble sugar and ABA in dormant fruit trees were significantly higher than those of the others in apple, and peach flower buds which was not release endodormancy by high temperature treatment arrested the development of flower buds.
- According to the climate change scenario RCP 8.5, chilling accumulation is expected to decrease rapidly since the 2080s in Korea. The area that does not meet 1000CU is expected to occur around the south coast of Gyeongnam province in Korea, and consequently it is supposed to the farming of major cultivars will be poor in fruit trees.
○ Development of chilling requirement and suitable domestic model for peach and apple trees.
- As a result of the modeling for peach, the effective temperature range of -2.0 ~ 6.0 ℃ was confirmed, and the standard error of chilling requirement was the lowestin chilling hour model and the Ichon peach model(the new model).
- As a result of the modeling for apple, the effective temperature range of -6.0 ~ 9.9 ℃ was confirmed, and thestandard error of chilling requirement was the lowest in Chungju apple model(the new model).
○ Survey on the chilling requirement of the fruit trees in the northern, central and southern region of Korea
- Investigation of the chilling requirement for breaking of internal dormancy in the commercial apple cultivars(‘Fuji’ and ‘Hongro’), pear(‘Niikata’, ‘Wonhwang’), peach(‘Kawanakajima Hakuto’, ‘Janghowon Hwangdo’), grape(‘Cambell early’, ‘Heukboseok’) at the Chuncheon region for 2 years(from 2018 to 2019)

□ Expected Contribution
The results of this study will be used as an assessment of the impact of agriculture on climate change. And it is to contribute the establishment of a breeding strategy related tochilling requirement of fruit trees.
