초록
본 연구는 셀레늄(Se) 처리가 ‘원황’ 배 과실품질에 미치는 영향을 구명하고자 실시하였다. 과실의 색상과 과형은 처리 간에 차이가 없었다. 모든 Se처리는 과실 내 칼륨과 Se함량을 높였으며, 과실의 단맛을 높이고 신맛을 줄이는 결과를 나타냈다. 저온 저장 시 과실의 경도를 조사한 결과, 모든 Se 처리구에서 대조구보다 높은 과실경도를 유지했다. 또한 Se 처리구에서, 높은 과실 비중과 과육 내 치밀한 세포 조밀도를 나타내서, 배 과일의 상품성을 저하시키는 바람들이 현상을 감소시켰다. 전체적으로 Se 처리방법에 따른 과실품질의 유의적인 차이는 크지 않았으나, Se 엽면살포구에서 보다 더 나은 상품성 과실을 생산할 수 있는 토대를 마련하였다.
Abstract
We explored how ‘Wonwhang’ pear fruit quality was affected by selenium (Se) application. The fruit skin color and fruit type differed between Se-treated trees and controls. Se-treated fruits had higher potassium and Se concentrations, more fruit soluble solids, and lower acidity, compared to the controls. All Se treatments improved fruit firmness during cold temperature storage compared to the controls. Also, Se-treated fruits had greater specific gravity and minuteness, which reduced fruit pithiness and rendered test fruits denser than the controls. Overall, Se foliar application improved fruits marketability compared to the Se fertilization or Se trunk injection.
