摘  要:
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(PAL)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。在红色叶片中的自由水和总含水量相对较低,这可能有利于花色素苷类物质的合成。

摘  要:
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(PAL) 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.The content of total water and the free water was relatively low in red leaves,faworable to the syrcthesis of anthocyanin.
