摘要
以长春市街路绿化树种复叶槭为调查对象,研究不同栽培群体的性别分化和有关种实性状,结果表明：在几乎相同的栽培环境中,不同群体雌雄株性别分化比例差异显著,雄株多于或显著多于雌株;株间种实的大小与翅果开张角度等形态性状存在差异或明显差异;株间的种子饱满度变动在33.8%84.1%之间,差异极显著;株间种子的千粒重变化范围在30.345.6 g之间,均值为36.0 g,差异极显著（F0.01=503.41＊＊）,遗传差异是主要因素。
The sex ratio and seed traits of Acer negundo populations growing on different streets were investigated in Changchun city.The results showed that the sex ratio was significantly different among different populations,though male individuals were more than females.There were different or significantly different morphological traits,such as seed size and opening angle of samaras.The seed plumpness varied between 33.8%84.1%.The thousand seed weight varied between 30.35.6 g,with average weight at 36.0 g,the difference is very significant（F0.01 = 503.41 ＊ ＊）,and genetic difference was the main factor of these variations.
