| 摘 要： | 以引进俄罗斯不同种源欧洲垂枝桦为材料,对其播种苗生长进行了系统比较研究。结果表明:不同种源欧洲垂枝桦播种苗生长具有极显著的差异,其地径和苗高的生长量大小依次为新西伯利亚种源>巴尔瑙尔种源>阿尔泰种源>对照种源;模糊综合评价法分析表明,不同种源欧洲垂枝桦播种苗生长量排序依次为新西伯利亚种源>巴尔瑙尔种源>阿尔泰种源>对照种源,新西伯利亚种源是不同种源欧洲垂枝桦播种苗中综合生长量最大的一个种源。

| Abstract: | A systematic comparative study on the seedling growth of Betula pendula from different Russian provenances was carried out. The results showed that there were significant differences in seedling growth among different provenances of Betula pendula;the growth of ground diameter and seedling height of different provenances of Betula pendula were in the order of Novosibirsk provenance > Balnauer provenance> Gorno-Altaysk provenance > control provenance;Fuzzy comprehensive evaluation showed that the order of seedling growth of European Betula pendula from different provenances was Novosibirsk provenance >Barnauer provenance > Gorno-Altaysk provenance > control provenance, and the Novosibirsk provenance is one of the provenances with the largest comprehensive growth among different provenances of seedlings. |
