Abstract

This study investigated the effect of AVG treatment on lipid material changes in the 'Hongro' apple epidermis. The internal ethylene concentration in 'Hongro' apples treated with $200mL{\cdot}L^{-1}$ AVG and stored at room temperature after harvest was significantly lower than that in 'Hongro' apples treated with $20mL{\cdot}L^{-1}$ Ethephon and the controls. During the same period, the emission of wax after the AVG treatment was also significantly lower than that after the other treatments. In conclusion, treatment with $220mL{\cdot}L^{-1}$ AVG two weeks before harvesting was found to be effective in improving and maintaining the quality of the 'Hongro' apples. Reducing the level of internal ethylene can delay the aging of fruit and inhibit the accumulation of wax in the fruit epidermis.

본 연구는 AVG처리가 '홍로'사과 표피의 지질물질 변화량에 미치는 영향을 구명하고자 실시하였다. 수확 후 상온에서 저장한 '홍로'사과의 내생 에틸렌 농도는 $220mg{\cdot}L^{-1}$ AVG처리구는 무처리구와 $200mL{\cdot}L^{-1}$ Ethephon처리구에 비해 현저히 낮은 수준을 보였으며, 같은 기간 지질물질 발생량도 다른 처리구보다 낮은 수준을 유지하였다. 따라서 수확 2주전 $220mg{\cdot}L^{-1}$ AVG처리는 내생 에틸렌 농도를 낮추어 과실의 노화를 지연시킬 뿐만 아니라 과실 표피의 지질물질 축적도 줄여줌으로써 상온유통이 되는 '홍로' 사과의 과실품질 향상 및 유지에 효과적이다.
