摘要
以烤烟品种Hicks和SpeightG 2 8为材料 ,针对烟草RAPD分析中PCR过程的Taq酶浓度、Mg2 +浓度、退火温度、循环数、Primer浓度、dNTP浓度等因素进行了研究。结果表明 ,体系中含 0 .8UTaq酶 ,4 0mmol/LMgCl2 ,10 μmol/L引物 ,3.0mmol/LdNTP ,循环数为 4 0 ,退火温度 36℃效果较好。从而确立适合烤烟RAPD分析的PCR程序主要条件 。
With tobacco variety Hicks and Speight G 28 as experimental materials, taqase concentration,Mg 2+ concentration,annealing temperature,number of amplified cycles,primer concentration and dNTP concentration of RAPD analysis were studied. The results indicated that under the condition of 0.8 U taqase, 40 mmol/L MgCl 2, 10 μmol/L primer, 3.0 mmol/L dNTP, annealing temperature at 36 ℃and 40 cycles, the effect was very good. RAPD pattern founded in this experiment layed good foundations for application of RAPD analysis in tobacco variety identification and germplasm research.
