臺灣原生鐵炮型百合族群間種子苗生長速率及開花之比較

本試驗探討臺灣原生鐵炮型百合族群實生苗間生長與發育之差異。採集自臺灣北部、中部及南部等13個棲地的鐵炮型百合種子，經低溫層積處理後於2015年9月播種，種子發芽後以128格穴盤及二寸黑軟盆假植二階段育苗，於翌年2月每族群定植60株2-4片葉的簇生苗於田間，同年8月各族群的開花率介於0%-75%不等，北部海岸（含離島）族群開花率低，介於0%-29.8%，開花期集中於6月份；中部族群開花率介於35%-48%，南部族群開花率則介於38.3%-75.0%；中部及南部族群的開花期集中於7月及8月。後龍族群於抽莖後1個月露蕾及開花，於4月盛花，為最具早熟開花能力的族群。北部海岸族群葉片寬短、中南部族群葉片長度及寬度在族群間變異大，可相差約兩倍，顯示臺灣原生鐵炮型百合族群間保有穩定且具差異的生長及開花性狀。

The aim of this study was to compare the growth and development difference of longiflorum-type lily native populations in Taiwan. The seeds of longiflorum-type lily collected from 13 habitats of Northern, Central and Southern Taiwan, and they were sowed in September, 2015 after seed stratification treatment. The seedlings were transplanted to 128-cell plug and 2-inch pots. A total of 60 setted seedlings carrying 2-4 leaves per population were planted in the field in February the following year. During August the flowering rate of each population among from 0% to 75%. The flowering rate of the northern population(including outlying islands) was low, ranging from 0% to 29.8%, and the flowering period mainly in June. The percentage of flowering plants of the central region of Taiwan ranged from 35% to 48%, and the southern population of that ranged from 38.3% to 75.0%. The flowering period of the central and southern populations was mainly in July and August. The flower buds and flowering were visible after one month after shoot sprouted, and bloom in April for Houlong population, which showed the earlier flowering ability. The length and width of the leaves of the northern coastal communities are short and large, and vary in the central and southern population, about twice as large as that of the other groups. The studies indicate that there are stable, differential characteristics and flowering traits among the longiflorum-type lily native populations in Taiwan.
