摘要
大青杨种内群体间变异十分丰富,为了选出最佳群体,直接用于造林,进行了全分布区群体选择的研究。本试验在大兴安岭地区对9个产体群体的大青杨做了生长、生根、抗寒、抗锈病的主要经济性状的测定,然后进行综合评定,选择出最佳群体。
The variations among populations within species for Populus ussuriensis arevery rich. The study on population selection in its whole distribution regionhas been conducted for selecting best population which can be used in forest-ation directly. Firstly, the main economic characters of Populus ussuriensispopulations collected form 9 places of origin, such as growth, rooting ability,cold and rust resistance have been determined in Daxinganling, then evaluatingthese economic characters comprehensively, finally the best population has beenselected.
