ABSTRACT
Extremely low values of the daily minimum temperature occurred in January 2010, ranging from -18 to -29oC at various locations growing peach trees in the Gangwon province. Due to the extreme cold temperature during the winter dormancy period of peach trees, the growth of the peach trees was damaged and the damaged areas increased as the extent of 17 to 144 ha. In order to provide information on mitigation measure of the cold temperature on the peach trees in the Gangwon province, we assessed the distribution of the damaged areas of growing the peach trees in 2010 and compared it with freezing risk estimated from the dormancy depth of the peach trees and the daily minimum temperature. The dormancy depth of ‘Changhowon Hwando (Prunus persica (L.) Batsch)’ ranged from -62 to -90 and the freezing risk was greater than 51%. The relationship between the freezing risk and the actual damaged area ratio showed reasonable agreement (r2 of 0.5 with p < 0.01). The results imply that the estimates of the freezing risk based on the dormancy depth can be used as a mitigation measure to identify susceptible peach growing areas to freezing damage injury.

적요

강원도 주요 복숭아 재배지의 2010년 1월 7일의 일 최저기온 분포는 -18 ~ -29oC로서, 평년보다 10oC 이상 낮았으며 복숭아의 동해온도로 설정된 -18oC보다 낮았다. 이로 인한 저온 피해 면적은 원주 144ha, 춘천 89ha, 영월 33ha, 횡성 22ha, 양구 17ha, 홍천 16ha 등이었다. 금후 강원 지역의 복숭아 동해에 대한 대책을 수립하는 데 기초 자료를 제공하고자 실제 동해 면적율과 휴면심도를 바탕으로 한 동해위험지수를 비교하였다. 자동기상측정장치가 설치된 지역의 일 최고기온과 일 최저기온, 기준온도를 바탕으로 계산한 장호원황도의 휴면심도는 -62 ~ -90였다. 휴면심도와 일 최저기온으로부터 계산된 동해위험지수는 51% 이상이었고, 이 동해위험지수는 실제 피해 면적 비율과 통계적으로 유의한 선형 관계를 나타내었다. 장호원황도의 휴면심도를 바탕으로 한 동해위험지수로 정확한 저온 피해 예측에는 어느 정도 한계가 있으나, 과수농가에서 복숭아의 동해를 대비하는 데 유용하게 활용 할 수 있을 것으로 판단된다.
