摘要
自2000年开始先后从俄罗斯季米里亚泽夫农学院的试验站引进欧洲红果花楸苗木，当年定植在苗圃试验地，之后进行了嫩枝扦插、组培繁殖，对其生物学特性、生长节律、栽培技术等进行了系统研究。结果表明，欧洲红果花楸在辽西地区具有很强的适应性，生长迅速，开花结果正常。嫩枝扦插和组培育苗经归圃培育后平均苗高30cm以上。成活率80％，8年生树高4．1m，地径6．7cm，单株果实产量4．0kg，产果量5．0t·hm^2。同时，花朵优雅夺目。果实为红色，鲜亮持久，可挂到冬季，引人注目，可美化城市、改善环境。
Abstract
Sorbus aucuparia, which have been introduced from experiment station of K. A. Agricultural College of Russia Since 2000,were planted in experimental plots of nursery to study their softwood cuttings ＆ tissue cuhure;their bio- logical characteristics, growth rhythm, cultivation techniques have been systematically studied. Result shows that Sorbus au- cuparia has a strong adaptability in western Liaoning, with rapid growth and normal flowering. Softwood cuttings ＆ tissue culture were condutcted nursery culture;seedling height are above 30 cm, survival rate being 80% , tree height of 8-year-old trees being 4.1 m,ground diameter being 6.7 cm,fruit yield per plant being 4.0 kg,yield of fruit being 5.0 t hm2. At the same time, flowers are elegant ＆ eye-catching;the fruit which is red ＆ bright durable can be linked to winter; those who are compelling can beautify the city ＆ improve the environment.
