彩叶杨彩色性状及园林应用研究

Study on Populus×euramericana ’s Color Characters and Landscape Application

以彩叶杨中的中红杨、全红杨为试材,以加杨为对照,于2011年秋季,测定了3种杨树叶片中的叶绿素、类胡萝卜素、花青素含量,并结合田间叶色表现状况,分析了3种杨树各自的叶色优势,探究了彩叶杨色彩鲜艳、稳定、持久的理由,得出了彩叶性状排序为全红杨>中红杨>加杨,同时,阐述了各树种的彩叶性状及使用观点,为彩叶杨进一步引种栽植及园林应用提供参考依据。

With Populus ×eurarnericana cv. Zhonghuahongye, and Populus × euramericana cv. Quanhong of Populus × euramericana as test materials, and with Populus canadensis Moench as controls,in the autumn of 2011, the chlorophyll, the carotenoids and anthocyanins of three kinds of poplar blades were examined;the color advantages of the three kinds of poplar leaves were analyzed with the leaf color performance by the bar chart and statistical analysis and also the reasons for the color brightness, stability, the duration were studied. The results showed that sort of colored characters for three kinds of Po pulus were： Populus × euramericana cv. Quanhong〉 Populus Y, euramericana cv. Zhonghuahongye〉 Populus canadensis Moench. At the same time, this paper expounded the colored characters and use methods,and applied the basis for the further introduction of Populus×euramericana and provide the reference to its landscape application.
