RT-PCR was a sensitive and stable method. It would be useful for large-scale diagnosis.A length cDNA of CEVd had been cloned into plasmid vector. Biotinylated probes were prepared from these plasmid DNAs. CEVd were examined from the positive and netative materials by Dot-blotting hybridization and imprint-hybridization. The result was exposed to x-ray film. Singles were detected for positive materials spots probed with probe, indicating that under the reaction conditions the probe hybridized with the target viroid specifically.

Laser confocal scanning microscopy is a new technology combining modern optics and electronics. The unique feature of point light source and point detecting eliminates out-of-focus blur and spots. Therefore, the axial and lateral resolution of the system is superior and 3-D imaging can be realized by scanning point by point of the object profile. Because of its advantages, confocal measurement technology is widely applied in many fields, such as medical treatment, biology, configuration of substances and micro-electronics.

激光共焦扫描显微术是结合了现代光电技术的新型扫描显微成像方法，其独特的点照明与点探测机理排除了离焦光线对图像造成的模糊和斑点影响，因而具有出众的轴向分辨率和横向分辨率；采用扫描技术在样品表面的各点逐点扫描，能够实现对微小物体的三维成像，因此在医疗、生物、物质结构、微电子等领域均具有广泛的应用。
