Abstract

This study was carried out to investigate the effects of tree-spray of calcium formate compound extracted from oyster shell with several active agents on the calcium concentration, fruit skin shape and quality of 'Fuji' apple. The tree-spray of calcium formate compound extracted from oyster shell (Os-CaF, $52.4\;mg{\cdot}kg^{-1}$) appeared to have more effectiveness on the calcium translocation into leaves, fruit skin and flesh than control. Addition of adjuvants to Os-CaF increased calcium concentration of 'Fuji' apple when sprayed three times before harvest. Among the active agents examined, the treatment ascorbic acid and poly-vinyl alcohol (PVA) in leaves, Ag-colloidal and PVA in fruit skin, ascorbic acid, Ag-colloidal, and PVA in fruit flesh exhibited highest effectiveness. Fruit qualities (fruit weight, firmness, soluble solids, acidity and Hunter value) were not affect by Os-CaF on different concentrations and solutions of active agents.

본 연구는 굴 껍데기로 제조한 개미산 칼슘화합물에 몇 가지 활성제를 첨가한 용액 수관살포가 사과 '후지' 과실의 칼슘농도, 과점의 발육 및 품질에 미치는 영향을 구명코자 실시하였다. 굴 껍데기로부터 추출한 칼슘 화합물(Os-CaF, $52.4mg{\cdot}kg^{-1}$)을 수관살포하였을 때 조직으로의 칼슘전이 효과는 무처리에 비하여 잎, 과피 및 과육에서 현저한 증가를 보였다. 그리고 Os-CaF에 활성제를 첨가하여 살포하였을 때 '후지' 과실의 칼슘함량은 증가되었다. 특히, 잎에서는 ascorbic acid, polyvinyl alcohol을, 과피에서는 Ag-colloidal, polyvinyl alcohol을, 과육에서는 ascorbic acid, Ag-colloidal, polyvinyl alcohol을 첨가한 칼슘화합물이 칼슘 흡수량을 현저히 증가시켰다. 칼슘화합물의 농도 및 활성제 종류에 따른 과실품질(과중, 경도, 가용성고형물, 산 함량, 과피색)은 차이가 없었다.
