水稻细菌性条斑病(以下简称细条病)是我国南方稻区的主要病害之一。该病是由种子带菌传播的,但目前国内尚缺一套带菌种子的快速、灵敏的诊检方法。为此,我们应用免疫放射分析技术,建立了水稻细条病病原的速检方法,并初步应用于诊断水稻病叶、病种等样品。应用结果证明,该方法具有快速、简便、灵敏、可靠等优点,有一定的推广应用价值。 Rice bacterial leaf streak (hereinafter referred to as thin strip disease) is one of the major diseases in southern rice in China. The disease is transmitted by the seed carrier, but at present there is a lack of a set of fast, sensitive diagnostic methods for carrying the seed. To this end, we used immuno-radioactive analysis techniques to establish a rapid inspection method for the pathogens of rice streak and preliminary application in the diagnosis of rice diseased leaves, diseases and other samples. The application result proves that the method has the advantages of fast, simple, sensitive and reliable, and has certain promotion and application value.
