This studies were conducted to investigate the effects of rain shelter and netting on the tree growth, fruit set fruit quality of kiwifruit (Actinidia deliciosa). In rain shelter and net house, shoot falling wasn't occurred by strong wind, and fruit set, fruit weight and also fruit malformation, side flowering increased at the same time. In rain shelter house the increment temperature forced blooming date and increased shoot length, leaf number and diameter but in net house these tendencies were not observed. Relative light intensity of rain shelter house was higher than that of net house with standard of field culture (relative light intensity: 100%). Soluble solid content was higher in rain shelter house, and acid content was higher in net house. With the effect of rain sheltering the occurrence of bacterial bloom rot and canker significantly decreased in both rain shelter and net house but insect injury increased. These data showed that rain shelter house is more suitable for kiwi fruit culture.

This study was established to investigate the effects of Ca application on fruit mineral nutrients, quality, and browning of 'Fuyu' sweet persimmon (Diospyros kaki). Ca foliar application at 40ml/20L/tree had a greater fruit Ca concentration than did control, Ca fertigation (40ml/20L/tree), and Ca foliar application (40ml/20L/tree) coupled with IBA fertigation (40ml/20L/tree). Fruit mineral nutrient concentrations for Mg, B, and Mn were similar or lower in the foliar treatment compared to other treatments. Fruit color was not affected. Ca treatment, whether foliar applied or fertigated, was effective in maintaining fruit firmness and in decreasing the browning symptom in fruit after MA storage at $0^{\circ}C$ for 60 and 100 days. Although Ca foliar application + IBA fertigation treatment improved fruit firmness, the positive effect on the browning and decay occurrences in fruit was not shown. 본 연구는 '신고' 배나무에 Ca처리 방법을 달리 했을 때 과실 내 무기성분과 품질 그리고 갈변율에 미치는 영향에 대해서 조사하였다. Ca 엽면시비는 대조구, Ca 관주처리, 그리고 Ca 엽면시비+IBA 관주 처리에 비해 유의적으로 높은 과실 내 Ca 함량이 나타났다. 과실내 Mg와 B 그리고 Mn 농도는 Ca 엽면시비에 의해 다른 처리구에 비해 오히려 낮거나 비슷한 수준이 나타났다. 과실의 착색은 처리구간에 별다른 차이가 없었다. Ca 엽면시비와 관주처리는 저온저장 후 0, 60, 100일 후에 대조구에 비해 과실의 경도를 유지시켰고 갈변율을 감소시켰다. 저온저장 100일 후에 10일간 상온에 두었을 때도 비슷한 현상이 나타났다. Ca 엽면시비+IBA 관주 처리의 경우 대조구에 비해 과실경도를 유지시켰지만, 과실의 갈변과 부패율은 대조구와 비슷한 수치를 보여서 이에 대한 연구가 필요하다고 하겠다.

This study was established to investigate the effects of Ca application on fruit mineral nutrients, quality, and browning of ‘Fuyu’ sweet persimmon (Diospyros kaki). Ca foliar application at 40㎖/20L/tree had a greater fruit Ca concentration than did control, Ca fertigation (40㎖/20L/tree), and Ca foliar application (40㎖/20L/tree) coupled with IBA fertigation (40 ㎖/20L/tree). Fruit mineral nutrient concentrations for Mg, B, and Mn were similar or lower in the foliar treatment compared to other treatments. Fruit color was not affected. Ca treatment, whether foliar applied or fertigated, was effective in maintaining fruit firmness and in decreasing the browning symptom in fruit after MA storage at 0℃ for 60 and 100 days. Although Ca foliar application + IBA fertigation treatment improved fruit firmness, the positive effect on the browning and decay occurrences in fruit was not shown.
