摘    要:以龙井43为材料,使用国产PCR仪,对茶树RAPD分析中影响PCR扩增结果的因素进行了研究,确定了茶树RAPD的最适反应系统和扩增程序,即在25μl反应体系中,含25~50ng模板DNA、2mmol/LMgCl2、各0.2mmo/LdNTPs、0.2μmol/L引物和0.5~1.0UTanDNA聚合酶;扩增程序为:94℃预变性180s,94℃变性60s,38℃退火90s,72℃延伸120s,共进行40~45个循环,最后72℃延伸300~600s,这样可以取得较好的扩增结果。

关 键 词:茶树  RAPD  反应系统  扩增程序

Abstract:The optimal reaction mixture and amplification procedure of RAPD in tea plant Camellia sinensis (L. )O. Kuntze] was studied with Chinese thermocycle machine Model-1109 (2A)). The results showed that each 25 μl amplification reaction solution was consisted of 25-50 ng template DNA, 2 mmol/L MgCl2,0. 2 mmol/L dNTP of each, 0.2 μmol/L primer and 0.5-1.0U Taq DNA polymerase. The amplification procedure conditions were predenature at 94℃ 180 s followed by denature at 94℃ 60 s, anealing 38℃ for 90 s, extension 72℃ for 120 s, cycling from 40 to 45 times, last extension 300-600 s and then the optimum procedure for tea plant DNA amplification was obtained.
Keywords:Tea plant (Camellia sinensis) RAPD Amplification reaction mixture Thermal procedure
