摘　　要： 光照是影响彩叶植物叶色变化的重要因素,与植物色素合成及彩叶植物呈现不同色彩变化有关。本试验用不同遮荫处理研究光照强度对斑叶鸭跖草的影响。试验结果表明,随着光照强度的下降,叶长×宽(cm×cm)、可溶性蛋白质含量和可溶性糖含量是先升高后下降,而叶绿素含量和花色素苷相对含量则是下降。经比较,一层遮荫处理的斑叶鸭跖草最具观赏性。 Illumination is one of the important facts which influence the leaves colors of color-leaves plant.The pigments synthesize and the leaves colors of color-plant are affected by illumination.In this work,the effects of illumination intensity on Zebrina Pendula were studied with different shading.treatings.The results show that the color of leaves change with the decreasing of illumination intensity.The length-width（cm×cm）,soluble protein and soluble sugar content all increase with the decreasing of illumination intensity firstly,but decrease then.The chlorophyll and anthocyanin content all decrease with the decreasing of illumination intensity.In conclusion,the ornamental characteristic of Zebrina Pendula leaves is optimum with monolayer shading treating.
