入侵植物繁殖生物學之研究-非洲鳳仙花

近年來生物之傳播，以藉由人類的活動而快速蔓延。當一外來生物進入一個新的生育地時，可能會因不適應環境而無法生存，也可能會因適應性及繁殖力極強而大量繁殖蔓延，甚至威脅到原本生育地植群的生存與繁殖，例如非洲鳳仙花，本計畫欲瞭解這些入侵種之生物學，並探討防治的方法以作為實際防治參考依據。非洲鳳仙花1966年由胡煥彩氏自日本引進，在景觀園藝上大量廣泛栽植，但是由於本種植物繁殖力高，耐陰性強，已經入侵至中低海拔的森林中，台灣有3種原生的鳳仙花，是否會對原生種造成威脅是本計畫的目標。In recent decades, the spread of organisms has accelerated rapidly driven by human activities. When a non-native organism enters a new habitat, it may fail to survive due to environmental incompatibility, or reproduce and spread rampantly owing to its strong adaptability and reproductive capacity, even threatening the survival and reproduction of native plant communities. For example, African impatiens. This project aims to investigate the biology of these invasive species and explore control measures to provide practical references for field prevention and management. African impatiens was introduced from Japan by Mr. Hu Huancai in 1966, and was widely cultivated in landscape horticulture. However, due to its high reproductive capacity and strong shade tolerance, it has invaded forests at middle and low elevations. There are three native Impatiens species in Taiwan, and whether this invasive species will pose a threat to these local native species is the core objective of this project.
