Abstract: 邓恩桉是一种优良的耐寒桉树,它在我国的推广利用因受无开花结实所限,邓恩桉组培生根困难,为使其能尽快得以推广本文进行了邓恩桉的组培生根试验,试验结果表明:6-BA 0.5 mg·L-1是最适于启动邓恩桉丛生芽的发生.激素组合6-BA 0.5mg·L-1+NAA 0.1 mg·L-1和6-BA 0.3 mg·L-1+NAA 0.2 mg·L-1的交替使用可用于邓恩桉的继代培养,IBA0.5 mg·L-1可用于邓恩桉的生根培养,在生根试验中观察到温度低于15℃时邓恩桉根尖变黑,组培苗植株上下部停止生长.大量元素对邓恩桉生根的影响最大,其次是微量元素和有机物,对其影响最小的是蔗糖.
