中文摘要 | 秋海棠科(Begoniaceae)在台灣地區之原生種有1屬、17種,本研究調查台中縣新社鄉抽藤坑地區之秋海棠科植物分布現況。經沿選定路線調查結果共記錄秋海棠科1屬、5種:圓果秋海棠Begonia aptera Blume、溪頭秋海棠Begonia chitoensis Liu & Lai、鹿谷秋海棠Begonia lukuana Liu & Ou、巒大秋海棠Begonia palmata D.Don及岩生秋海棠Begonia ravenii Peng & Chen。其中溪頭秋海棠、鹿谷秋海棠及岩生秋海棠為台灣特有種;而鹿谷秋海棠、岩生秋海棠在本區之分布狹隘且族群數量稀少。抽藤坑地區近年休閒產業快速發展,在開發時應注意稀有植物之保育。本區之5種秋海棠科植物均具觀賞價值,可研究繁殖及育苗技術,將原生種秋海棠推廣應用於環境綠美化,以展現當地生態特色並保存原生植物基因資源。 |
英文摘要 | This study surveyed the distribution of the Begoniaceae in Chouterngkeng area (Shienshe District, Taichung County). One genus and five species were recorded: Begonia aptera Blume, B. chitoensis Liu & Lai, B. lukuana Liu & Ou, B. palmata D. Don and B. ravenii Peng & Chen. Three species of them were endemic: Begonia chitoensis, B. lukuana and B. ravenii. Begonia lukuana and B. ravenii were locally distributed and rare. The tourism had been developed in the Chouterngkeng area in the past few years. Rare plants must be protected in the process of development. The five species of the Begoniaceae found in Chouterngkeng area were showy in both foliage and flowers and; therefore, they were under serious threats due to human over-exploitation. Artificial propagation and cultivation may possibly decrease the impact of exotic plants and thereby display the special feature of local ecosystem. |
