摘要

卡地娜品種馬鈴薯之不同繁殖體，包括組識培養小薯球、組識培養瓶苗、瓶苗2次扦插苗、單節插苗、薯芽插苗、頂芽插苗、薯塊等七種，種植於田間，藉以了解馬鈴薯繁殖時對產量的影響。試驗結果調查株高，單株產量、50 gm以上大薯總重、小薯總重、大薯數目及小薯數目等六個項目。變文分析結果顯示，不同繁殖體對六個性狀的米現都有顯著差異，一般均以薯塊繁殖表現最佳，頂芽插苗次之，惟兩者間差異不顯著。組織培養瓶苗及試管內小薯球的表現最差，僅及薯塊繁殖產量的1/6~1/7。而薯芽插苗、瓶苗二次扦苗及單節插苗則介於二者之間。本試驗結果可供基本種薯生產改進採用。

For seed potato propagation, the comparative growth and yield of potato by different propagules of Cardinal cultivar were investigated. Seven kinds of propagation sources including (1) conventional tuber pieces, 12-15 g each (2) rooted tissue culture plantlets (3) microtubers, 0.5-0.6 g each (4) apical stem cuttings from rooted tissue culture plantlets (5) single-node cuttings from transplanted tissue culture plantlets (6) sprout cuttings from tubers and (7) apical stem cuttings from young plants originated from tubers were planted in the field in nethouse. The statistical analysis was made on the data of plant height, yield of tubers, number of large and small tubers, total weight of large and small tubers obtained from all propagules. Conventional tuber pieces as well as the apical stem cuttings from tuber derived young plants gave the beat performance for all the data recorded, Rooted tissue culture plantlets and microtubers, when planted in the field directly, gave the poorest yield of tubers which only counted for 1/6-1/7 of those from tuber pieces. The results from this experiment would be helpful for the improvement .of seed potato propagation in Taiwan.
