本試驗使用二種火鶴花栽培種Sarina及Etna為材料，以不同遮光程度及不同光質處理等方法，探討火鶴花之生理反應。兩品種依白色尼龍網、75%遮光之黑色網、50%遮光之黑色網、75%遮光之黑色網、75%遮光之銀色網、紅色玻璃紙、藍色玻璃紙及黃色玻璃紙等處理結果，皆以75%黑色網遮光處理的植株生長及開花品質最佳；而白色尼龍網及紅、藍、黃三種不同顏色玻璃紙處理的植株低矮、外形開張、開花品質差。葉片組織結構以75%黑色網之遮光處理者，柵狀組織細胞較短，海綿組織細胞大小則呈不規則狀分佈。三種不同顏色玻璃紙處理者，柵狀細胞短而排列較不緊密，海綿組織細胞則較大。Sarina品種以75%黑色網之遮光處理，葉片深綠色；以紅色玻璃紙處理，則呈黃綠色。佛焰花苞在50%及75%黑色網之遮光處理下，呈粉紅色；在藍色玻璃紙處理下，則呈淡橘紅色。Etna品種以50%黑色網之遮光處理，葉片綠色；以黃色玻璃紙處理，葉片呈黃綠色。佛焰花苞以白色尼龍網處理，呈鮮紅色；以紅色玻璃紙處理，則呈暗紅色。

Investigation of physiological responses of various shading grades, light quality, major nutrients efficiency, and long day treatment of Anthurium andreanum Linden under different enviromental conditions, Two cultivars, 'Sarina' and 'Etna' were used in this experiments.From the results of treatments by 75% and 50% shade with balck PE screen, 75% shade with silver PE screen, and by red, blue and yellow glassine; the best growth and flowering quality of plants were obtained by 75% shade with black PE screen. White nylon screen and three glassines caused short in plant morphology, and poor in flowering quality. Under 75% shade with black PE screen and three different glassines, cross section of leaves had short palisade cells, the size of spongy mesophyll cells were not regular in distribution. Spongy mesophyll cells were more larger in glassine treatments than in others.'Sarina' provided by 75% shade with black PE screen had green leaves, while yellow-green leaves by red glassine. Spathes color of 'Sarina' under 50% and 75% shade with black PE screen were pink, and light orange under blue glassine.'Etna' provided by 50% shade with black PE screen had green leaves, or yellow-green leaves by yellow glassine. Spathes color of 'Etna' were bright red while under white nylon screen, darkred under blue glassine.
