摘  要：
在辽宁省章古台经多年引种育苗试验表明 ,引种苗木特别是 1年生苗能否正常越冬 ,成为引种成败的首要限制因子。就欧洲赤松而言 ,波兰、爱沙尼亚种源 1年生苗的越冬保存率在 80 %以上 ,2年生苗生长量与樟子松相仿且均能安全越冬 ,为适宜种源 ;在试验过的 4个欧洲黑松变种中 ,Pinusnigravar.austriaca较抗寒 ,1年生苗木越冬保存率可达 96 % ,2年生苗木全部能安全越冬 ,是最有希望的变种。挪威云杉苗木不能露地越冬 ,不宜作造林树种引种 ,可作为绿化树种试栽。

摘  要：
The results of introduction and seedling cultivation trials for many years in Zhanggutai of Liaoning province indicated that if the introduced seedlings, particularly one-year seedlings could survive the winter has become the first restricted factor for the success or failure of introduction. As forPinus sylvestris, conservative rates of one-year seedlings of Poland and Estonia provenances after the winter were over 80%, the growth of two-year seedlings was similar to that of Pinus sylvestris var. mongolica and could survive the winter safely, and were regarded as suitable provenances. Among 4 varieties of Pinus nigra tested, Pinus nigra var. austriaca was cold-resistant, its conservative rate of one-year seedlings after the winter reached 96%, all its two-year seedlings could also survive the winter safely, and was the most promising variety. Seedlings of Picea abies could not survive the winter in open fields, and was not suitable for introduction as a afforestation tree species, it might be tested as a greening tree species.
