Correlation among Quality Attributes and Storability by Fruit Weight in 'Fuji' Apples = '후지' 사과 과실의 품질 인자간 상관 및 과실 중량에 따른 저장성

국문 초록 (Abstract)

안동과 영양지역의 '후지' 사과를 공시하여 과실의 품질요인간 상관성 및 과실의 중량과 저장력의 연관성을 분석하였다. 두 과수원 과실에서 공통으로 보여진 유의적인 상관관계는 역의 상관으로써 과중-경도, 과중-착색도, 과중-Hunter 'b'값 간이었고, 착색도-Hunter 'a'값 및 당함량-산함량 사이에서는 정의 상관성이 나타났다. 과중과 당함량 및 과중과 산함량 간에는 두 과수원에서 모두 상관성이 없는 것으로 분석되었다. 한편 과중과 색택 요인간 상관성은 두 과수원에서 상이하게 나타났는데 안동 지역 사과의 경우 과중-착색도는 유의성은 없으나 역의 상관 계수를, 과중-Hunter 'a'는 유의적인 역의 상관성을 보인 반면, 영양지역 사과에서는 과중-착색도 및 과중-Hunter 'a'값간에 유의적인 정의 상관을 보였다. 과실 경도와 당산 함량의 변화 정도로 판단한 저장력과 과중간에는 뚜렷한 상관성이 보이지 않았다.

Relationship of fruit weight with other quality parameters and storablity were evaluated in 'Fuji' apples harvested on a commercial harvest date from two orchards located in 'Andong' and 'Youngyang' area. Inter-correlations among quality parameters were also analyzed. Significant correlations observed in both orchards were; nigative relationships between fruit weight and flesh firmness, surface color and Hunter 'b' value, positive relationship between surface color and Hunter 'a' value, and soluble solid content (SSC) and juice acidity. Correlations between fruit weight and SSC or juice acidity were not significant in both orchards. In Contrast. between the two orchards, opposite correlation coefficients were observed in the combination of fruit weight with surface color. The correlation coefficient was negative, although insignificant, in 'Andong' apples, whereas significantly positive in 'Youngyang' apples. Likewise, fruit weight was negatively correlated with Hunter 'a' value in 'Andong' apples, while positively correlated in 'Youngyang' apples. No clear relationship was observed between fruit weight and storability as estimated by changes in flesh firmness and flavor parameters.
