单倍体小黑杨对潮霉素的敏感性研究

Study on the Sensitivity of Hygromycin on Populus simonii×P.nigra

以单倍体小黑杨的叶片、不定芽和茎段为材料进行潮霉素敏感性研究的结果表明,在叶片筛选阶段,潮霉素的适宜浓度为3.0mg/L;在抗性芽和茎段生根筛选阶段,适宜浓度分别为2.0和6.0mg/L。

Take Populus simonii × P. nigra leaves, stem segment and adventitious buds as materials, the hygromycin sensitivity was studied. The results showed that screening stage in the leaves, hygromycin the appropriate concentration of 3.0 mg/L, resistant buds and stems rooting screening stage, suitable concentration of 2. 0 and 6.0 mg/L.
