Abstract

The effects of liquid calcium fertilizer (LCF) extracted from oyster shell on the calcium contents and fruit quality during the storage of grape fruits were studied. The calcium contents in leaf blade and petiole of ‘Campbell Early’ and leaf blade, petiole and stem of ‘Kyoho’ were increased, but fruit peel showed no difference between LCF-treated and non-treated. There were no differences of berry number, berry weight, soluble solids contents, and acidity between the fruits of two cultivars. The cluster weight of ‘Kyoho’ was increased by LCF treatment. The weight loss of ‘Kyoho’ fruit after 60 days of cold storage was reduced by both LCF vine-spray and combined cluster dipping treatment. Berry shattering of ‘Kyoho’ and ‘Campbell Early’ fruits after 90 days of storage by LCF treatment were significantly decreased. However, fruit cracking and decaying were not observed. Soluble solids contents of fruit after 15 days of storage increased by fruit dipping and combined vine-spray treatments of LCF, but soluble solids contents and acidity after 90 days of storage showed no difference.

포도 과실에 칼슘 함량을 증진시키기 위하여 굴 껍질을 원료로 한 액상 석회 비료를 처리한 후 칼슘 함량, 수확 시 과실 품질 및 저장 중 품질에 미치는 영향을 조사하였다. ‘캠벨얼리’ 엽신과 엽병, ‘거봉’은 엽신, 엽병 및 수경의 칼슘 함량이 액상 석회 비료 수관 살포에 의하여 증가되었으나, 과피에서의 칼슘 함량은 차이가 없었다. 수확 시 과립 수, 과립중, 가용성 고형물 함량, 산 함량은 차이는 없었다. 액상 석회 비료 수관 살포로 ‘거봉’의 과립중은 증가하는 경향이었으나 과방중은 증가되었다. ‘거봉’은 저장 60일 후에 무처리과에 비하여 수관 살포과와 수관 살포+과실 침지과가 과방중의 감량률이 적었다. ‘거봉’의 탈립률은 전처리 모두 감소하였으며 특히 ‘캠벨얼리’에서는 저장 90일 후에 액상 석회 비료 수관 살포에 의해 감소되었다. 열과 및 부패과 발생은 처리간 차이가 없었다. 가용성 고형물 함량은 저장 15일 후에는 과실 침지과 및 수관 살포+과실 침지과에서 많았으나, 저장 90 일 후에는 차이가 없었고 산 함량도 처리간 차이가 없었다.
