Abstract

This experiment was conducted to determine the effects of the pre- and post-harvest variable factors on the processed product of kimchi cabbage cultivated in semi-highland at summer time. Kimchi cabbage cultivar 'Chun Gwang' was grown in an open field and/or under a plastic greenhouse condition; it was stored at 0? after harvesting with low-density polyethylene (LDPE) film packaging. The pre-harvest characteristics growth parameters, fresh weight, head weight, no of leaves, leaf thickness, firmness, moisture content etc. were evaluated. The evaluated postharvest characteristics were fresh weight loss, appearance, trimming loss, SPAD value, moisture content and hue angle. The results show that the fresh weight and leaf thickness were higher in 'Chun Gwang' kimchi cabbages grown in the greenhouse than those in the field. However, the other evaluated factors were not affected by the type of cultural method. During the storage, the cabbage continued to decrease in fresh weight loss, trimming loss and moisture content. When compared to the kimchi cabbage showed significant difference in the fresh weight loss, trimming loss and moisture content during storage. It was confirmed that both cultural methods indoor- and outdoor did not show head growth parameters of 'Chun Gwang' kimchi cabbages on semi-high land at summer time. Although no difference in the growth before storage was observed, the evaluated characteristics like fresh weight loss etc. were influenced by cultural method as a pre-harvest factor. This study suggests that there were to be affected by pre-harvest factor during storage after harvest. In this study, an integrated management system combining relationship between processed agricultural products and their pre- and post-harvest factors.

고온기 준고랭지에서 재배한 배추의 생육과 저장에 미치는 영향을 구명하고자 하였다. '춘광' 배추를 홍천에서 재배 방법(노지 및 시설 재배)에 따른 생육 특성과 수확 후 저장 시 특성을 조사하였다. 수확 후 생육은 시설 재배한 배추가 생체중과 엽두께에서 노지 재배와 차이를 보였지만, 가식부인 결구 부분에서는 큰 차이를 보이지 않아, 재배 방법에 따른 생육에 미치는 영향을 언급하기 어려웠다. 준고랭지에서 재배한 '춘광' 배추의 저장 시 생체중이나 정선 손실률, 수분함량 등에서 유의 차이를 보였다. 동일 지역에서 시설과 노지로 재배를 달리한 경우 생체중량이나 정선 손실률은 시설 재배가 변화폭이 더 커서 유의 차이를 보였으며, 수분함량은 다소 낮아지는 것으로 나타났다. 본 연구를 통해 고온기 배추의 수확 후 저장 시 차이가 나타났음을 확인하고, 수확 전 요인이 저장까지 영향을 미치는 유기적인 관계를 확인하였다. 농산물에 대한 생산성 위주의 연구가 주류를 이루었으나, 앞으로는 생산뿐만 아니라 저장 동안의 영향을 확인 할 필요가 있다.
