摘　　要：为了丰富北方寒冷地区珍贵园林绿化树种资源,于1986年从波兰引进欧洲花楸种子,进行了播种繁殖,对其植物学特性、生物学特性、生长节律等进行了系统研究。结果表明:欧洲花楸生长迅速,生长高峰期出现在7月中下旬,全年生长期为120d左右。3年生实生苗进入快速生长期,年平均生长量达146.3cm;5年生实生苗即可开花结果。该树种适宜在东北地区推广栽培。Seed propagation of Sorbus aucuparia was conducted with the seeds introduced from Poland in 1986 aiming to enrich the species resources for afforestation in cold regions of North China. The botanical characteristic, biological characteristic and growth rhythm of S. aucuparia were studied. Results show that S. aucuparia grows rapidly in Harbin, and its growth peak appears from mid to late July. The growing period of S. aucuparia is about 120 days. The three-year-old seedlings enter into a fast-growing period with a mean annual increment of 146.3 cm. Five-year-old seedlings blossom out and produee fruit. S. aucuparia is suitable to be widely popularized in Northeast China.
