Abstract

The study was conducted to investigate the correlation analysis between fruit quality and climatic parameters in grapevines. 'Campbell Early', one of the major grape cultivars, occupies more than 70% of cultivated areas in Korea. Recent research results have shown that the movement of cultivation area of fruit production resulted from the temperature increase. In this study, we investigated the relationship between fruit quality and climatic conditions in 13 major 'Campbell Early' grape producing areas (i.e., Sacheon, Jinju, Naju, Dangjin, Cheonan, Gimcheon, Yeongdong, Okcheon, Sangju, Suwon, Yeongju, Gangneung, Chuncheon, and Yanggu). The earliest and latest full blooming days of grapevines were ovserved on May 25 in Sacheon area and on June 7 in Yanggu area, respectively. At least 90 days are required for grapes to mature enough for the production of highquality fruits. The southern areas with less than 90 days of maturity period had difficulty in the production of good fruit. However, the areas with longer maturity period of 100 to 110 days produced grapes with with high sugar content and good coloring. The fruit qualities of 'Campbell Early' grapes are more closely related with temperature than other climatic factors. High temperature resulted in fruits with high acidity and delayed the coloration of the fruit skin in the southern area. The fruit skin was thin in the southern area and inclined to be thicker in the northern areas. Therefore, grape should be cultivated in regions with long maturity period to have high quality.

포도 캠벨얼리 품종은 우리나라 포도재배면적의 70%이상을 차지하고 있는 대표 품종이다. 최근 기후변화에 따른 기온상승으로 과수 재배지의 변동에 대한 연구가 활발히 진행되고 있다. 본 연구에서는 기후요소와 과수품질간의 상관관계를 밝히기 위해 우리나라 주요 포도 주산단지 사천, 진주, 나주, 당진, 천안, 김천, 영동, 옥천, 상주, 수원, 영주, 강릉, 춘천 그리고 양구 등 13곳의 과원을 대상으로 조사하였다. 개화기는 사천이 5월 25일로 가장 빨랐으며 강원도 양구는 6월 7일로 가장 늦었다. 포도는 성숙일수가 90일 정도 되어야 상품성 있는 품질을 생산할 수 있다. 하지만 남쪽지방에서는 성숙일수가 90일 보다 작다. 강원도 지방은 성숙일수가 100일에서 110일로 가장 길다. 그래서 과실의 당도가 높게 나타난다. 포도 캠벨얼리의 과실 품질은 기상요인 특히 온도와 밀접한 관련이 있으며 온도가 높으면 산도가 높다. 과피두께는 남부지방 과실의 과피가 얇고 북쪽으로 갈수록 과피가 두꺼워지는 경향을 나타냈으며, 과실의 착색에서 남부지방은 수확적기가 지났음에도 착색이 불량하며 북쪽지방은 아직 적숙기가 되지 않았다.
