摘要
采用经过选择的毛白杨优良单株的嫩枝、嫩叶、休眠过的芽和单芽茎段等外植体进行组织培养,诱导出愈伤组织。愈伤组织继代增殖分化出大量无根小苗,再诱导生根成苗,然后炼苗、田间移栽、成活率达87％。
Describes the callus culture of dominant individual of Chinese white poplar (Populus tomentosa Carr.) by using shoots, leaflets, post dormant buds, and single bud stems as explant materials. Callus was formed and differentiated into numerous rootless plantlets, which were induced to rooting. After hardening off, the rooting plantlets were transplanted to nursery. The survival rate reached 87%
