Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.

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。
