摘　　要：为了丰富吉林省西部地区造林及绿化树种,在白城市林业科学研究院试验示范基地,选择7个胡桃楸种源进行栽植试验,生长期结束后对7个胡桃楸种源进行苗高和基径的测量,并对5个优良种源环境因子的影响进行了分析评价。结果表明:辉南、集安、露水河、红石和蛟河的胡桃揪种源生长均较好,苗高与不同种源地的年均气温、年降水量、年日照时数呈正相关,基径仅与年均气温呈负相关,蛟河种源在白城市生长良好且遗传稳定,与白城市环境更为接近,初步确定蛟河种源适合白城市造林。In order to enrich the afforestation and greening tree species in western Jilin Province,seven prove-nances of JuglansmandshuricaMaxim were selected for planting experiments.After the growing period ended,the seedling height and basal diameter of the seven JuglansmandshuricaMaxim provenances were measured,and the impact of environmental factors on the five excellent provenances was analyzed and evaluated.The results showed that Huinan,Ji'an,Lushuihe,Hongshi,and Jiaohe all grew relatively well.Seedling height was positively correla-ted with the annual mean temperature,annual precipitation,and annual sunshine duration of different provenance areas.Basal diameter was only negatively correlated with the annual mean temperature.The Jiaohe provenance grew well and had genetic stability in the Baicheng area and was closer to the environment of Baicheng.It is ini-tially determined that the Jiaohe provenance is suitable for afforestation in the Baicheng area.
