摘要：以杨树叶片为外植体，进行组织培养试验研究。结果表明：叶脉和叶柄处极易产生不定芽；培养基中BA浓度是影响不定芽形成的关键；BA浓度在0.5～2mg/L 范围内均有不定芽产生，BA1.0 mg/L 与NAA0.05 mg/L 配合使用，可促进不定芽的形成；培养基中添加 GA3 0.1～0.2mg/L，可以提高不定芽的发生频率。在此基础上建立杨树叶片离体再生体系，利用该体系能够获得高的芽苗再生频率，但是不同品种间略有差异。

Abstract: Plants the body take the poplar tree leaf blade as outside, conducts the tissue culture experimental study. The result indicated that, The leaf vein and the petiole place is extremely easy to produce does not decide the bud; In the culture medium the BA density is the influence does not decide the key which the bud forms; The BA density has in 0.5 ~ 2mg/L scope does not decide the bud production, BA1.0 mg/L and NAA0.05 the mg/L coordination use, may promote not to decide the bud the formation; In the culture medium increases GA3 0.1 ~ 0.2mg/L, may enhance does not decide the bud the occurrence frequency. Establishes the poplar tree leaf blade in this foundation to the body regeneration system, uses this system to be able to obtain the high bud seedling regeneration frequency, but during the different variety slightly has the difference.
