Abstract

Investigation of relationship between meteorological factors and fruit characteristics of 'Fuji' apple was conducted at six orchards in three major production area in Korea, which are denoted by alphabet from A to F. The fruit weight of C, and D orchard located in Chungju was the heaviest whereas that at the F orchard in Jecheon was the lightest. We found that the whole growing period showed the positive correlation with maximum temperature but negative correlation with minimum temperature, especially, there was highly positive correlation between whole growing period and the amount of precipitation on October. The fruit L/D ratio, which is known to be affected by cool temperature from full bloom stage, was the highest at the D orchard in Chungju. The fruit firmness was also the highest at the D orchard and the E orchard in Jecheon where the average temperature was low. The soluble solids is the highest at the D orchard and the E orchard which are located at high altitudes. From this data, it was found that the soluble solids were affected by the amount of insolation and duration of sunshine which showed the positive correlation. The acidity was the highest at the D orchard and there was statistically significant in sugar-acid ratio by the regions. Anthocyanin contents was the highest at E and F orchards in Jecheon where the monthly mean temperature was low in October. Hunter value a showed the significance at the D orchard which is located at high altitudes. Hunter value L was much positively correlated with the average temperature, but negatively correlated with the amount of insolation in October. Hunter value a was much negatively correlated with the average and minimum temperature, but positively correlated with the amount of insolation in October. Hunter value b was much positively correlated with the average and minimum temperature.

사과 기상변화로 인한 사과 '후지'는 개화기는 빨라지고 생육기간이 연장됨으로서 품질변화를 가져오고 있다. 시험포장은 청원, 충주 및 제천에 각 2농가를 선정하였고, 기상 측정장비 4기를 설치하여 3년간 기상자료를 수집하였으며, 과실특성과 기상요소 간 상관을 분석한 결과 다음과 같은 결론을 얻었다. 과중은 충주 C, D과원에서 제일 크고, 제천 F과원이 작았다. 전 생육기의 최고기온과 정의 상관, 최저기온과 부의 상관을 나타냈다. 강수량은 10월에 고도의 정의 상관을 나타냈다. 과형지수는 만개 후 서늘한 기온이 종경비대에 영향을 미치는 충주 D과원이 높았다. 또한 경도는 평균기온이 낮은 충주 D과원과 제천 E과원에서 높았다. 당도는 표고가 높은 충주 D과원과 제천 E과원에서 높았다. 8월 이후 수확 때까지의 일사량과 일조시간이 정의 상관을 보여 당도에 영향을 미치는 것을 알 수 있다. 산도는 충주 D과원에서 높았는데, 4월~7월 유과기 최고기온과 일교차에서 부의 상관을 최저기온에서 정의 상관을 보였다. 감미비는 지역간 통계적인 유의차를 보였다. 안토시아닌 함량은 10월 평균기온이 낮은 제천 E, F과원에서 높았다. 9월~10월, 10월의 평균기온이 고도의 유의한 부의 상관을 보였다. 착색도는 표고가 높은 충주 D과원에서 유의하였다. 명도는 평균기온이 고도의 정의 상관을 10월의 일사량이 고도의 부의 상관을 나타내며, 적색도는 평균기온 및 최저기온이 고도의 부의 상관을 10월의 일사량이 고도의 정의 상관을 나타내며, b값은 평균기온 및 최저기온이 정의 상관을 유의하게 나타냈다.
