摘 要：
应用ＰＣＲ技术对柑桔黄龙病病原ＤＮＡ进行体外扩增，可建立一套快速、准确、有效的检测该病原的方法研究结果表明：ＰＣＲ技术对柑桔黄龙病病原的检测具有很强的特异性，只有感染了黄龙病病原的样品，ＰＣＲ才呈阳性反应文章报道了应用ＰＣＲ技术能检测已带病但尚未显症状的柑桔黄龙病病株该检测技术可以对柑桔黄龙病进行早期诊断，及早地控制带病苗木的传播，这对选育无病苗木及病害的综合治理具有很高的应用价值

摘 要：
The present study is aimed to develop an effective method for the detection of Liberobacter asiaticum that causes citrus Huanglongbing disease. It was shown that the DNA of the pathogen could be amplified by polymerase chain reaction (PCR) in vitro and the appearance of such DNA was significantly detected in the samples of infected citrus trees of the various cultivars. To use PCR for the detection of the infected trees without any symptom yet at the early stage of the infection. This technique can be effectively applied to screen disease free seedlings, establish disease free citrus nurseries, and control the spread of the diseased seedlings.
