本試驗利用鈣、矽肥料處理土壤,調查果實貯藏生理變化情形,然後找出適合肥料用量,以期增進甜椒貯藏品質。試驗結果顯示,施用鈣、矽肥可增加果實中鈣、磷之含量。適當的消石灰(2、3、4kg/4.5 m^2)、矽酸爐渣(2、4kg/4.5 m^2)處理可增加果實的硬度及果肉厚度。施用鈣、矽肥可減輕果實貯藏時對低溫之敏感性,延緩寒害發生。對照組之甜椒貯藏於5℃下3天,則出現呼吸率增高、乙烯大量生成及果實表面陷點病斑形成等寒害現象。鈣肥處理組之果實貯藏於5℃下延至6天後才會發生寒害,而矽肥處理除2kg處理組外,也是6天後才會出現寒害病徵。鈣、矽肥料處理對貯藏於室溫下之甜椒果實有抑制其呼吸率、乙烯生成量之作用,而果實硬度、果肉厚度、電導度,以鈣肥各處理、矽肥2kg處理組品質較佳。
The objectives of the experiments were to investigate the effects of calcium and silicon pretreatments on post- harvest physiology of sweet pepper. Treatments of calcium and silicon fertilizers increased the concentration calcium and phosphate in fruits. Calcium at the rate 2,3,4 kg/plot and silicon 2,4 kg/plot enhanced firmness and thickness of fruits. Fertilizer treatments also reduced chilling injury and cold sensitivity of fruits. Treat ments of calcium and silicon fertilizers lowered the respiration rate and ethylene production, however, treatments of calcium and 2kg silicon improved fruits quality such as firm ness, thickness and electrical conductivity.
