摘要
‘中红杨’来源于杨树品种2025的芽变,经多年研究培育而成。雄株,较速生。从春季芽萌动到初夏整株叶片及新发嫩枝紫红色,初夏以后到10月中旬新发嫩叶及嫩枝为鲜艳的紫红色,而中下部成熟叶片则变为红绿色,10月中旬以后整株叶片逐渐变为桔黄色,直至落叶。适宜种植范围广。
Populus deltoides ＇Zhonghong＇ （Chinese Red Foliar Poplar） is a new poplar variety which was cultured through multiple years＇ selection. It originated from a bud mutation of the poplar variety 2025. The male tree of ＇ Zhonghong＇ grew fast, and the variety would be a good ornament tree because its foliar color varied in different season. The foliar and twig appeared purplish red color from sprout period to early summer, and the new leaf and twig exhibited vivid violet-red from early summer to mid-autumn with the mature leaf in the mid-lower crown green, and then the leaves became apricot-red gradually after midautumn until defoliation. The variety was adaptable to grow in many regions of China.
