摘要: 番石榴具週年生產的特性,目前外銷量逐年增加,每月均有出口,為提升外銷競爭力,穩定供貨品質及供貨量是必要條件。 臺灣番石榴主要外銷加拿大、中國等地,歐盟市場則尚待開發,但因其船運路線較長,擬透過1-MCP處理,以維持果實品質及延長櫥架壽命。目前番石榴外銷品種單一,以'珍珠拔'為主,應加強外銷品種多樣化以提升外銷競爭力。近年紅肉番石榴在國內市佔率增加,加拿大市場初步調查亦深具潛力,本計畫將建立紅肉西瓜拔外銷加拿大之貯運流程。 線蟲為害為番石榴栽培之重要損耗,常造成植株死亡,有必要建立良好防治策略以減少損耗。 另外,因應氣候變遷,前期計畫已進行番石榴耐逆境品系篩選,已選出若干耐逆境單株,將進一步觀察其耐逆境表現及植株生育等相關園藝性狀。 本年度計畫將改良外銷歐盟市場之採後處理技術,並建立紅肉番石榴外銷加拿大貯運技術;此外,開發線蟲非農藥栽培防治技術、及選育耐逆境之番石榴新品系。 Guava can be produced all year round. Its yield and exporting quantities is increasing in Taiwan, which got monthly exportation. In order to improve the competitiveness in exporting market, stability of product supply and quality are necessary. Canada and China are the two main exporting market countries of Taiwan guavas. The EU market is yet to be developed. But its transportation time is longer. In order to maintain the storage life and shelf quality, we prepared to use 1-MCP treatment to achieve the goal. Currently, the exporting guava cultivar is mainly 'Jen-Ju'. For elevating the export competitiveness, the varieties of exporting guava should be diversified. Red-flesh guava in Taiwan domestic market share increased recently. And the preliminary market survey of Canada showed great potential. In this project, we prepared to establish the export transportation and storage process, to promote the export of red-flesh guava to Canada. Nematode infestation is a serious disease in guavas, which often cause plant death. It is necessary to establish a plant protect strategy. Besides, climate change has influenced guava production. In response, we did the hybridization, and selected some stress tolerant lines by Chlorophyll fluorescence(Fv/Fm). The following-up work is to investigate the stress reactions, the growth characters and the relating horticultural traits. Overall, the project this year is going to improve the post-harvest preservation process for guava exporting to EU market, and establish the storage and transportation technique of red-flesh guava. For the more, we are going to develop the non-chemical material nematode prevention technique, and select one or more stress-tolerant guava lines.
