摘　　要：在安徽省怀宁县皖河滩地对湘林77、80、90南林95等4种杨树无性系进行了引种育苗试验。结果表明:在2008年5月20日至10月20日,4种杨树无性系苗木地径、苗高生长均随时间呈线性增加态势;不同无性系苗木地径和苗高生长差异显著,其中南林95和湘林80表现较好。The introduction experiment of four poplar clones included Xianglin 77, 80, 90 and Nanlin 95 was conducted in Wanhe Beach of Huaining county, Anhui. The results showed that the ground diameter and height of four clones were increased with time from May 20 to Oct. 20, 2008. The four clones had significant differences in the growth of ground diameter and height. Comparatively the clone Nanlin 95 and Xianglin 80 showed better in growth traits than the others.
