以黄龙林区引种的8个瑞典能源柳无性系为研究对象,开展了形态学特征、物候、病虫害与日灼、1a生苗木生长量等调查。结果表明,1a生瑞典能源柳无性系扦插苗,以瑞能A、瑞能C和瑞能E高径生长量最大;病虫害和日灼对引种能源柳危害比较小;瑞典能源柳在3月中下旬开始叶芽萌动,展叶期一般为1周左右,多数开花无性系花期超过1月;瑞能2和瑞能4花期长,观赏价值高,更适于作为园林绿化树种;清水浸泡插穗以瑞能A和瑞能成活率最高,分别为96%和93%,其它6个无性系成活率介于73%～89%之间。

Eight Swedish energy willow clones were studied in Huanglong forest region.The morphology characteristics,phenology,pests,sunburn,growth of annual cutting seedlings were observed.The results showed that 1-year old cutting seedlings for clone A,clone C and Ruineng clone E had maximum height growth and base diameter.The symptom of pests and sunburn for all clones were not serious.The leaf bud germination of Swedish energy willow clones started in mid and last ten days of March;leaf extension period was usually about 1 week;and flowering stage of majority flowering clones were more than 1 month.Clones 2 and Clones 4 had long flowering periods and with the ornamental value;All clones cuttings were soaked in water for 24 hours,and the survival rate of Clone A and Clone E were 96% and 93%,survival rate of the other clones were between 73%~89%.
