Abstract

This study was conducted to investigate the effect of 1-methylcyclopropene (1-MCP), a known ethylene action inhibitor, on fruit quality and incidence of physiological disorders during simulated marketing period in Asian pears (Pyrus pyrifolia Nakai) of early-season cultivar 'Hanareum' and mid-season cultivar 'Manpungbae'. Flesh firmness was decreased abruptly at 15 days after shelf-life in untreated fruit of early-season cultivar 'Hanareum' which showed less than 19N, although those of 1-MCP-treated fruits were kept high value (>28N) during 15 days of shelf-life. However, there were no distinct firmness changes during 30 days of shelf-life in mid-season cultivar 'Manpungbae' pear. Two pear cultivars did not show any considerable differences in quality indices such as soluble solids content, titratable acidity and skin color during the shelf-life regardless of 1-MCP treatment. The reduction of ethylene production level by 1-MCP treatment did not appeared in 'Hanareum' pear. Meanwhile, 1-MCP treated 'Hanareum' pears showed significantly low respiration rate during shelf-life. On the other hand, the inhibitory effect of 1-MCP was not remarkable in mid-season 'Manpungbae' pears. 1-MCP treatment completely blocked the incidence of physiological disorders including core browning and mealiness symptom during shelf-life only in early-season 'Hanareum' pears, and reduced considerably the pithiness disorder regardless of 1-MCP concentration. Consequently, we concluded that the treatment efficacy of 1-MCP is largely cultivar-dependent and the use of $1{\mu}L{\cdot}L^{-1}$ 1-MCP was recommended for the keeping quality and the prevention of physiological disorders only in early-season Asian pear 'Hanareum'.

본 연구에서는 국내에서 생산되는 조생종 배인 '한아름'과 중생종 '만풍배'에 대해 에틸렌 작용 억제제인 1-methylcyclopropene(1-MCP)를 농도별로 처리하고 상온 유통기간 중 과실품질 및 생리장해 발생에 미치는 영향을 조사하였다. '한아름'은 상온유통 15일에 1-MCP를 처리하지 않은 모든 과실에서 경도가 급격하게 감소하였던 반면 1-MCP를 처리한 과실의 경우 처리농도와 관계없이 28N 이상의 높은 경도를 나타내었다. 그러나 '만풍배'의 경우 1-MCP처리농도와 관계없이 경도유지 효과는 크게 나타나지 않았다. 두 품종 모두 1-MCP처리후 유통 중 가용성고형물, 산 및 과피색과 같은 품질요인의 유의한 차이는 보이지 않았다. 1-MCP처리농도에 따라 '한아름'의 상온유통 6일 이후 에틸렌 발생량이 급증하는 시점이 다르게 조사되었으나, 에틸렌 발생량을 낮추지 못하는 것으로 조사되었다. 반면 '한아름' 과실의 호흡률은 상온유통 15일간 유의하게 낮게 조사되었으며, 1-MCP 처리농도가 증가함에 따라 호흡률 감소 효과도 증가하는 경향을 보였다. 한편, '만풍배'의 경우 1-MCP 처리농도에 따른 상온유통 중 에틸렌 및 호흡억제효과는 미비한 것으로 조사되었다. 1-MCP 처리에 따른 상온유통 중 생리장해발생 억제는 조생종 '한아름' 배에서만 유의하게 나타나 처리농도와 상관없이 상온유통 15일 동안 과심갈변과 분질과가 전혀 발생하지 않았으며, 바람들이 발생을 유의하게 억제하는 효과를 보였다. 따라서, 동양배에 대한 1-MCP처리 효과는 품종에 따라 다르게 나타나며 $1{\mu}L{\cdot}L^{-1}$의 1-MCP처리는 조생종 배 '한아름'에 있어 상온유통 기간 동안 과실품질 유지와 생리장해 억제에 효과적인 것으로 판단되었다.
