Calcium Hydroxide 처리가 양앵두 果實의 品質에 미치는 영향 = Effect of Ca(OH)_2 on Fruit Quality and Ca Content in prunus avium Fruit

국문 초록 (Abstract)

양앵두 佐藤錦 및 Napoleon品種을 供試하여 Ca(OH)_2 處理濃度 및 處理回數에 따른 果實生長, 果實品質, 칼슘축적 및 裂果에 미치는 影響을 調査하였던바 다음과 같은 結果를 얻었다.
1. 양앵두 果實生長은 佐藤錦품종에서 收穫1週前 Ca(OH)_2 처리농도간에는 차이가 없었으나, Napoleon품종에서 Ca(OH)_2 처리회수가 증가 할수록 抑制되었다.
2. 可溶性 固形物과 Anthocyanin함량은 Ca(OH)_2 처리농도 및 처리회수를 증가 할수록 감소하였으나, 유기산 함량은 증가하였다.
3. 果實內 칼슘축적은 Ca(OH)_2 처리농도 및 처리회수가 증가 할수록 증가하였고, 佐藤錦 품종에서 과실내 칼슘함량은 과피, 종자, 과육, 핵의 순이였고, Napoleon품종에서는 종자, 과피, 과육, 핵의 순이였다.
4. 裂果방지를 위한 Ca(OH)_2 처리는 7.2g/l를 수확 3주전부터 1週間隔으로 3회 살포하는 것이 열과를 감소시키는데 효과적이였다.

다국어 초록 (Multilingual Abstract)

The study was conducted to investigate the influences of several concentrations of Ca(OH)_2 and application time on fruit growth, quality, contents of Ca in fruits and cracking of 'sa Tou Nisiki' and 'Napoleon' sweet cherry.
The results obtained are summarized as follows;
1. In Ca(OH)_2 treatments, the fruit growth of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry was not influenced by its concentrations but by application times of Ca(OH)_2.
2. Contents of soluble solids and anthocyanin according to concentreation and application of Ca(OH)_2 were decreased, while titratable acidity was increased respectively.
3. Contents of Ca in the fruit according to concentration and application of Ca(OH)_2 were increased and Ca contents in both fruits differ from fruit portions.
4. Preharvest application of Ca(OH)_2 by 0.72% and three times applications reduced cracking of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry. From these results, twice applications of Ca(OH)_2 to the sweet cherry are recommended for the best fruit quality, the authors believed.
