Abstract

‘Wongwhang’ pear often suffered from the incidence of core and/or flesh browning, which is known to be associated with an improper postharvest handling including storage temperature. We examined the effect of storage temperatures and 1-MCP treatment on the occurrence of browning disorder in ‘Wonwhang’ pears (Pyrus pyrifolia Nakai). The incidence of flesh and/or core browning was not consistent to storage temperature (0-10℃). Fruit with high soluble solids and low firmness (more mature fruit) at harvest showed a tendency of high incidence of browning disorder regardless of storage temperature and the effect of 1-MCP (0.5 to 1 ㎕.L-1) on disorder occurrence was not clear. The browning disorder in ‘Wonwhang’ appeared to be rather affected by the maturity of fruit at harvest. Future study including determination of accurate maturity indices for harvest is required to prevent the postharvest suffering by browning disorder.

조생종 ‘원황’의 과육 및 과심갈변 장해와 저장온도 및 에틸렌제어의 효과를 검토하기 위하여 본 연구에서는 2년에 걸쳐 유사한 시기에 ‘원황’과 실을 수확하여 저장온도에 따른 생리장해와 1-MCP 처리의 효과를 조사하였다. 저장온도에 따른 장해의 발생은 해에 따라 일정하지 않았으며 비슷한 시기에 수확한 과실이지라도 가용성 고형물함량이 높고 경도가 낮았던 해의 과실에서 저장온도(0-10℃)에 관계없이 장해 발생이 심하였다. 1-MCP 처리는 갈변 발생에 미치는 영향이 명확하지 않았다. 따라서 ‘원황’의 갈변장해는 수확기의 과실의 성숙 상태의 영향을 받으므로 앞으로의 연구에서 ‘원황’의 적정 수확시기에 대한 보다 구체적인 연구가 필요할 것으로 판단된다.
