摘要
１９９４～１９９７年我们应用分光光度计法（光谱分析法），对引进的８种色叶树在生长季节叶片自身的光合色素及花色素含量生理指标测定，绘制光合色素含量随时间变化曲线，从而找到了不同季节叶色变化的成因（内因）。由于光合色素含量与温度的关系，光照度的强弱。
In the period of 1994～1997, by using method of spectrophotometer(method of spectrology), we carried out physiological data measurement for photosynthesized pigmentum and flower pigmentum content of leaves themselves of 8 varieties of color leaf tree in growth seasons, drew curves for changing of photosynthesized pigment content along with the time changes and in this we have found the internal reason of the leaf color changings in different seasons. It is because of the relationship between content of photosynthesized pigentum and the ambient temperature, the variations of external factors, including the intensity of sunlight, and length of sunshine lead to a color changing in leaves.
