摘要

台南白在台灣已有80年以上之栽培歷史，經農民自行留種及傳播全島，歷經不同生態環境的淘汰，顯示各地區之台南白族群內仍然維持著極大的變異存在，同時已有分化產生，地理位置處於較北的桃園及花蓮族群，其株高及葉面積最小；台中、彰化及雲林等中部族群，其株高及葉面積大於北部族群；屏東及台東較偏南之族群，其株高、葉片數及單株葉面積均為最大。整體而言，族群間營養性狀的表現呈現，屏東、台東＞台中、彰化、雲林＞桃園、花蓮。影響其分化的主要因子可能為溫度梯度造成。

Tainan-White (TNW) is a native maize population which has been cultivated for over 80 years in Taiwan. TNW has been conventionally ultilized as a green corn. Eight Tainan-White populations collected from Pingtung, Taitung, Tainan, Taichung, Changhua, Yunlin, Hualien and Taoyuan areas were planted at Wufeng in fall of 1994. The results showed significant differences in many agronomic characters among the eight TNW maize populations and large variation also existed among different populations. The vegetative characters (plant height, ear leaf length and leaf area per plant) of TNW populations collected from Taitung and Pingtung were higher than those of populations from the Taichung, Changhua, Yunlin, and the populations of Hualien and Taoyuan have the lowest plant height and leaf area per plant. The results indicated that the temperature of different areas maybe a main factor for the differentiation of the TNW maize populations.
