以烤烟品种中烟100为模板,利用两对 SCAR 引物,采用单因素和正交优化试验,研究烤后烟叶多重 PCR 反应体系中各主要因素的影响情况,建立了适合烤后烟叶多重 PCR 扩增的最佳反应体系:20μL 体系中含模板 DNA 45 ng,Mg2+浓度2.50 mmol/ L,dNTP 浓度0.40 mmol/ L,Taq 酶用量4.00 U.该体系多重扩增条带清晰,可缩短鉴别时间,为利用多重 PCR 技术鉴别烤烟 DNA 指纹图谱奠定了基础.

Using the single factor and orthogonal experiments with the flue-cured tobacco varieties of zhongyan100 as raw material and two SCAR primers to study the multiple PCR reaction system in the inter-action between the main ingredients of flue-cured tobacco leaves,the best suitable multiple PCR reaction system was established for roast tobacco including DNA template 45 ng,Mg2 + concentration 2. 50 mmol/L,dNTP concentration 0. 40 mmol/ L and Taq enzyme dosage 4. 00 U on the 20 μL system. The stripe of the system is clear and it can shorten the identification time,laying a foundation for using multiple PCR technology to identify flue-cured tobacco varieties.
