| 摘要: | 本計劃將決定洋桔梗切花品質之項目包括瓶插壽命,葉片外觀,小花開放程度,小花梗軟垂程度,花色表顯等,實驗初期將針對上述品質指標進行調查,作為進一步試驗的改善對象.根據業者經驗及本人初步觀察顯示:不同栽培種洋桔梗切花之耐貯藏性有明顯差異,本計劃將自虎尾,田尾,南投等地不同花農處購買三種以上之切花進行測試,調查其原始切花品質及經7至10日貯運後之出庫品質,以供業者及進一步研究參考.國內外均有學者指出,以不同乙烯抑制劑處理洋桔梗切花可改善其瓶插品質,但尚未有報告詳細調查以立式容器進行長期運輸,配合乙烯抑制劑的處理結果,燻蒸及液體之吸收將是本計劃之比較重點之一,濃度及處理時間將隨觀察結果機動調整.切花採收後以相對高蔗糖濃度溶液迫吸可改善許多切花之瓶插品質,但若於運輸期間持續吸收,所須濃度及種類尚有待試驗探討之,本處理將與上列其它處理一併進行,但配方之確實成份,尚須較長時間方可確立.
The present study will focus on the investigation of common problems occurred during the long-term storage of cut Eustoma flowers. Items studies including the appearance of leaf, opening of individual florets, and pigmentation of petals. The data obtained will be used to adjust the further formalation of postharvest treatment solution in the long run. Cultivars tested including cut flowers from various location cultivated by different local growers in Nan-Tou, Tien-Wei. Pulsing solutions used including those containing relatively high concentrations of sugars, and/or various sources of carbohydrate and/or ethylene inhibitors, namely, silver thiosulfate and 1-methyl cyclopropane. |
