The paper studied the physiological characteristics of the leaves of Cotinus coggygria Royal Purple with different colors in autumn. Three kinds of leaf colors were selected to measure the contents of chlorophyll, anthocyanin, phenylalanin ammo-nialyase activity and the water content in the leaves. The results showed that the leaves exhibited red if it had lower chlorophyll content, higher activities of PAL and higher content of anthocyanin. The green leaves had higher chlorophyll content, lower activity of PAL, less content of anthocyanin.

本研究以美国红栌秋季叶片为试材，选取红色，中间色、绿色三种颜色的叶片，测定其叶绿素、花色素苷、苯丙氨酸解氨酶活性及叶片组织中的含水量，讨论其对美国红栌秋季叶片着色的影响，结果表明：美国红栌秋季叶片中，红色叶片叶绿素含量较低，PAL酶活性较高，花青素苷的含量较高，所以叶色呈现红色；绿色叶片中叶绿素含量较高，PAL酶活性较低，花青素苷的含量较少，所以呈现绿色。

By the catalyzed of F3H, F3'H and F3'5'H, the biosynthesis of anthocyanins branched three pathway to form pelargonidin, cyanidin and delphinidin separately. DFR, F3'H and F3'5'H are the most important genes for introducing new metabolic branches by genetic transformation to plants that lack some kinds of flower pigments.

花色素苷的生物合成主要由于F3H，F3'H和F3'5'H三个关键酶的作用形成3个分支，最终分别生成橙色到砖红色的天竺葵素糖苷，红色的矢车菊素糖苷和蓝色到紫色的飞燕草素糖苷，因此， F3'H，F3'5'H和DFR基因是利用遗传转化引入花卉植物原本缺乏的花色代谢途径的关键基因。

The cyanin of Acer ginnala had low light and heat stability.It could hold the cyanin stability under low temperature and dark condition.

茶条槭的花色素苷表现出光、热稳定性差的明显特征，低温和黑暗条件能较好地保持花色素苷的稳定性。

Changes of leaf pigment content,soluble sugar content,enzyme activity and photosynthesis characters in leaf of Photinia×frasery"Red Robin"were searched of five different shading treatments(100%,80%,50%,25%,10%transmission rate).The seasonal variation of leaf color and stability of anthocyanin were studied in this paper.Purpose of the research is to master the Physiological characters during leaf color transformation of Photinia×frasery"Red Robin",and provide evidences to promote introduction cultivation and the application under different garden environment of them.

本文以2年生红叶石楠(Photinia×frasery'RedRobin)扦插苗为试材，探讨了不同遮光处理透光率分别为100%(全光照、80%、50%、25%、10%条件下叶片色素含量、可溶性糖含量、苯丙氨酸解氨酶活性、抗氧化酶活性变化及光合作用日变化，同时对其叶色的季节变化及花色素苷的稳定性进行了初步探讨，以掌握红叶石楠叶色变化的生理特征，为红叶石楠的广泛引种栽培及在不同园林环境中的应用提供科学依据。

The results showed that:1. Changes of Photosynthesis and Relative Physiological Characteristics of Photinia frasery Dress Seedlings under Different Drought in SpringAlong with the stress time extended and stress extent increased, leaf water content, photosynthetic pigment content and photosynthetic indexes of Photinia frasery Dress were inhibited in different levels, but the anthocyanin content, MDA content and membrane permeability increased distinctly.

结果表明： 1。不同程度干旱胁迫下红叶石楠叶片光合作用及相关生理特性的变化随着胁迫时间的延长和胁迫程度的加剧，红叶石楠的叶片含水量、光合色素含量以及Pn等光合基本指标都受到了更深程度的抑制，且可利用的光强范围越来越小，而花色素苷含量、MDA含量和细胞膜透性大幅增加，保护酶系统(SOD、POD、CAT)活性随着胁迫时间的延长，总体表现为先升高后降低，但在同一时期，随着胁迫程度的加剧，酶活的变化趋势有异。
