碩士 === 國立臺南大學 === 自然科學教育學系碩士班 === 94 === Lantana camara L., is an introduced invasive plant in Taiwan. The aim of this study is 1.) to study the autecological characteristics of Lantana camara L.; 2.) to investigate it’s geographical patterns and habitats; and 3.) to evaluate it’s reproductive capacity in Taiwan. There were three types of wild population belonging tetraploid (2n=44), and could be divided by different flower colour. Lantana produced flowers and fruits around the year in hot and humid temperature. Each flower head was made of 20-40 flowers, which 44% could produced fruits. Germination rate of fruit was 57%, but seed was 73%. Lantana invaded many areas belows 1000m above sea level in Taiwan, but severe in the wast area. Compared the plots with or without Lantana, Lantana could cover large areas and kill understory speies, but apparent inability to compete with the taller native forest plants. Lantana could invade many areas below 700 meters, especially in the ruderal sites created by man.
