摘要

以建立彩葉芋各品種基本特性資料為目的，本研究對廣葉品種26個品種及狹葉品種5個品種進行塊莖平均重、塊莖平均葉片數、平均葉柄長度、葉形以及萌芽率的快慢等品種基本特性進行調查。調查結果顯示同一品種塊莖平均重與塊莖平均葉片數及平均葉柄長度的數值之間並無相關性，塊莖重最重之品種並非葉片數最多或平均葉柄長度最長之品種。在植物生長調節劑對生育之影響方面，BA處理對葉片數的增加有一定的促進作用，但其效果不若去頂芽處理明顯。GA3的處理可明顯提高各品種的開花率及增加開花數，同時亦會使葉形變得較狹長。

For purpose of establishing the data of characteristics of caladium varieties, twenty-six varieties of C. bicolor and five varieties of C. pictulantum were used to investigate the tuber weight, leaf number, plant height, leaf shape and the speed of emergence rate. From the data we collected, there was no obvious correlation in tuber weight, leaf numbers and plant height between same or different varieties. Heavier tubers were not necessarily had more leaf numbers or owned higher plant height. BA treatment increased the leaf numbers, but not as much as terminal bud removal. GA3 treatment could raise the flowering rates and flowering numbers as well as induce the leaf shape into narrow.
