Abstract
本試驗利用大葉種(kenebec)及卡迪娜（cardinal)兩個馬鈴薯品種參試，於不同栽培地區及相同栽培環境之不同栽植期的氣候下，探討其對塊莖產量及薯形大小與乾物率等收稻品質之影響，1990年冬季裡作在后里、斗南及溪口三地栽植之結果顯示，大葉種在溪口地區栽値產量最高，卡迪娜則在后里地區產量最高。1991年冬季裡作在后里地區之栽植期試驗結果顯示，第一次植植（9月24日）之塊莖產量最高，隨栽植期之延後，塊莖產量都隨之降低：另就塊莖收穫品質而言，亦呈現與產量相似之情形，隨栽植期之延後而降低。1992年冬季裡作在溪口地區之結果則顯示，大葉種在早、晚兩_値期問，其產量均無大差異；但卡迪娜則以晚植期產量較高，惟早植者因塊莖肥大期受寒流及乾旱氣候影響，晚植者於塊莖形成期亦遭遇寒流及生長後期之雨量過多，故生產之塊莖多呈現不具經濟價値之形態，塊莖乾物率因生長後期突遇甚高雨量(189 mm)而下降。藉相關分析探討氣象因子與馬鈴薯生育間之相關關係，結果發現塊莖與全株乾重分配比例及生長後期之日夜溫差呈顯著正相關，塊莖乾物率與生育期氣溫及生育前期之日夜溫差呈顯著負相關，但與生育後期之日夜溫差及生育前期之日射量呈極顯著正相關。
Potato varieties, Kenebec and Cardinal, were used to study the effects of growth region and planting date on tuber yield and quality. Results indicated that tuber yield of kenebec of winter crop (1990) at Hsikou was the highest among the growth regions, but cardinal at Houli had the highest tuber yield. Among the four planting dates at Houli, it showed that both varieties obtained the highest yield and quality when planted on 24 September of 1991. In the winter crop of 1992，the tuber yield was similar for Kenebec planted at either earlier or later season at Hsikou. However, the yield of Cardinal was higher when planted earlier than that of planted later. The distribution ratio of tuber and whole plant dry weight were postively correlated with difference between day and night temperature of later growth stage. Percentage of tuber dry matter was negatively correlated with mean air temperature of whole growth period and difference between day and night temperature of early growth stage, but was postively correlated with difference between day and night temperature of later growth stage and solar radiation of early growth stage.
