1-Methylcyclopropene이 'Formosa' 자두의 품질과 유통기간 연장 Fruit Quality of 1-Methylcyclopropene Treated 'Formosa' Plum on the Shelf Life at Ambient Temperature원문보기
본 연구는 1-MCP가 'Formosa' 자두의 저장 중 품질 변화와 유통기간 연장에 미치는 효과를 밝히고자 수행하였다. 수확한 'Formosa' 자두를 균일한 크기와 색깔로 선별한 후 수확 당일 그리고 수확 후 1일 후에 걸쳐서 각각 1-MCP를 $1{\mu}L{\cdot}L^{-1}$ 농도로 $20^{\circ}C$에서 16시간 동안 처리하여 대조구(무처리)와 비교하였다. 1-MCP를 처리한 후 14일 동안 상온에서 자두의 연화도, 과중감소율, 가용성고형물 함량 변화, 산도, 그리고 과실의 색깔 변화를 측정하였다. 과중감소율과 과실연화도는 1-MCP 처리구가 무처리구에 비해서 적은 변화폭을 보여주었다. 1-MCP 처리 시기(수확당일 그리고 수확 후 1일) 간에는 따른 큰 차이는 없었다. 가용성고형물 함량에는 통계적 유의성은 없었으나, 1-MCP처리구의 과실에서는 산도와 과실의 색깔 변화가 무처리구에 비해서 적게 나타났다. 또한 1-MCP는 저장 중에 발생하는 과실의 부패병 억제효과를 나타내었다. 따라서 본 연구결과, 1-MCP 처리시기(${\geq}1$일) 연장은 상온저장시 과실의 경도, 산도, 과일 색깔 변화에 큰 영향을 미치지 않았으며, 또한 과실품질 유지에 실용성이 있는 결과를 보여주었다.

The effects of 1-methylcyclopropene (1-MCP) for controlling ripening processes such as weight loss, fruit softening, soluble solids content (SSC), titratable acidity (TA), and fruit skin color were investigated and also the possibility that 1-MCP can inhibit the development of brown rot was explored in 'Formosa' plum ($Prunus$$domestica$ L.). Fruit were treated with $1{\mu}L{\cdot}L^{-1}$ 1-MCP on the day of harvest and one day after harvest for 16 h at ambient temperature ($20^{\circ}C$), followed by 14 days of shelf life. 1-MCP treatment delayed fruit softening, weight loss and changes in skin color and TA during the shelf life period, but did not affect SSC. These 1-MCP effects were similar with and without delayed treatment. 1-MCP treatment inhibited the development of brown rot caused by $Monilinia$$laxa$ during storage. Our data shows that treatment delays of ${\geq}1$ day before 1-MCP application had no negative effect of fruit softening, fruit skin color, and TA at ambient temperature ($20^{\circ}C$). Overall, these results indicate that 1-MCP can be used to maintain the quality of non-refrigerated plums.

문제 정의
The objective of this study was to compare the effects of the delayed application of 1-MCP on the fruit quality over short periods of time (i.e., for 14 days) and on the development of brown rot under ambient temperature (20℃) during shelf life.
제안 방법
At each sampling time, five fruits from each of the three replications were used to determine weight loss, changes of flesh firmness, skin color, TA, SSC, and brown rot incidence. For color assessment, Hunter Lab System (L, a, b) in a colorimeter: CR200 model, (Minolta Camera Co.
) were harvested from a commercial orchard located in Yesan, Korea. The experiment was conducted using uniform sizes of fruits randomly replicated with five fruits per replicate for each treatment.
데이터처리
Each dependent variable was statistically analyzed using the general linear model procedure (PROC GLM) of SAS (version 8.02; SAS Institute, Cary, NC, USA). Following analysis of variance, mean separation was performed by Duncan’s multiple range tests (DMRT) at 0.
Following analysis of variance, mean separation was performed by Duncan’s multiple range tests (DMRT) at 0.05% level.
후속연구
In contrast, the response of 1-MCP on the incidence of brown rot was different by cultivars. Therefore, further study is required to confirm the effects of 1-MCP on the development of brown rot and storage disorders (Dong et al., 2002).
