中文摘要 | 椪柑為中部地區重要的果樹產業之一,為配合椪柑外銷作業,提早採收並施予低溫檢疫處理為整個產銷作業必要之流程。然而早採椪柑及低溫檢疫處理常導致轉色程度不足,因之本試驗乃進行益收生長素(ethephon)及NAA藥劑對椪柑果實提早、採前落葉與落果及經模擬低溫檢疫對其貯藏品質之影響試驗。試驗結果顯示椪柑雖經採後乙烯催色及15℃貯藏仍無法完全轉為橙黃色。於果實採收前1個月利用40~400 mg kg^(-1)益收生長素及300 mg kg^(-1) NAA溶液直接噴施果實,有利於椪柑果實在採收前提早轉色。但隨益收生長素施用濃度提高結果枝的落葉率也相對增加。在採收後果實品質處理方面,400 mg kg^(-1)益收生長素+300 mg kg^(-1) NAA處理組之果實周徑及可溶性固形物小於其他處理,酸度偏高且落葉率達38.9%。其餘不同濃度益收生長素處理之果實品質則與對照組無顯著差異。因此,果實採收前1個月利用40~100 mg kg^(-1)益收生長素+300 mg kg^(-1) NAA處理則有利於果實轉色且不影響果實品質。 |
英文摘要 | Ponkan Mandarin (Citrus reticulata Blanco) is one of the most important fruit tree industry in central Taiwan. To meet the demand for its exportation quarantine operation, early harvest with low temperature storage imposed necessary for the entire production and marketing processes. However, early harvest with 15 ℃ storage usually caused to poor coloration on Ponkan, therefore, an experiment with chemicals of ethephon and NAA on fruit coloration, pre-falling of leaf and fruit and fruit quality variation via simulated quarantine low temperature storage treatment on ‘Ponkan’ Mandarin (Citrus reticulata Blanco) was conducted. The result of this study showed that pre-harvest treatment with 40 to 400 mg kg^(-1) ethephon and 300 mg kg^(-1) NAA could increase the rate of coloration. However, defoliation effort also enhanced by the increase in ethephon concentration. Treatment with 400 mg kg^(-1) ethephon and 300 mg kg^(-1) NAA reduced the fruits size and total soluble sugar content, and the percentage of leaves drop was increased to 38.9%. Therefore, pre-harvest treatment with 40 to 100 mg kg^(-1) ethephon and 300 mg kg^(-1) NAA could improve the rate of coloration and not affect fruit quality. |
