摘要

彩葉芋在遮光栽培方面，依其不同品種、遮光程度而有顯著之差異。植株高度及葉片長度、寬度以遮光80%者為較大，分蘗數則以遮光40%者最多，但品種不同稍有差異。不同塊莖切塊數及藥劑處理對植株之影響，依塊莖繁殖之切塊數、藥劑處理種類、品種等不同而有顯著差異。切塊數少者，始葉之日數短，植株較高，葉片數及分蘗數多，葉兵及葉寬較大。利用Mancozeb（80% WP）處理者產生之分蘗數較之用Benomyl（50% WP）者為多。彩葉芋去除中心芽栽培者葉長、葉寬變小、植株較矮、始葉日數長、葉片數及分蘗數較多。

Growth of caladium (Celadium hortulsnum) plant in low light intensity by 80% shading with black PE screen caused more stretchable petioles and large-sized leaves than growth in 40% shady condition. Significant difference of horticultural traits of cultivars were also found under different grades in light intensity.Caladiums are tropical plant propagated mostly by tubers. Significant difference of chemicals and tuber pieces cutted were found under different source of treatments. Large tuber pieces caused shorter days to foliation, higher in plant, more shoots, and larger-sized leaves. Mancozeb (80% WP) applied to propagative tuber pieces resulted in more shoots than benomyl (50% WP) used.Tubers removed center bud produce more shoots and large leaf size than tubers planted intact and also sprout fastly.
