Abstract

This study was conducted to compare the internal and external fruit quality of highbush blueberry cultivars introduced in Korea. The fruit of blueberry showed a double S-shaped growth curve, and the fruit weight increased significantly per seed increased by 0.02 g. The sugar content ranged from 9.5 to 14.2°Bx, with a large difference between cultivars. And the free sugar was composed of glucose and fructose as a reducing sugar, and mannitol as a sugar alcohol. The organic acid content was 0.7~1.13%, and citric acid was higher than that of malic acid. Fruit hardness showed a berry characteristic that rapidly declined as the coloring progressed.

본 연구는 국내에 도입된 하이부시 블루베리 품종의 내외적 과실 품질을 비교하기 위하여 수행되었다. 블루베리의 과실은 이중 S자 생장 곡선을 나타내며, 과실 내의 종자 수가 많을수록 과중이 유의하게 증가하였고 종자 1개당 과중이 0.02g씩 증가하였다. 당도는 9.5~14.2°Bx로 품종 간 차이가 컸으며, 유리당은 환원당인 포도당과 과당, 당 알코올인 만니톨로 구성되었다. 유기산 함량은 0.7~1.13%였으며, 구연산이 사과산보다 많았다. 과실 경도는 착색이 진행되면서 급격히 떨어지는 장과류 특성을 보였다.
