生产调查表明,有病的水稻种子很可能是白叶枯病初次侵染的主要来源之一.多年来曾提出过一些种子检验方法,但还不完善,病种检验和消毒处理工作仍有一定困难.此外,对种子带菌传病也还没有取得一致的认识.这里介绍的几篇报告,在水稻白叶枯病种子带菌问题的研究中,采用的检验方法有:1.用抗链霉素的水稻白叶枯病菌突变种,在初花期接种水稻茎秆,成熟后收取病种,由病种分离这个突变种;2.用微吸管法分离颖壳的病原;3.对病种实行浓缩回接检验;4.噬菌体检验法.受检种子发芽后,镜检幼苗细菌溢并回接作致病性鉴定.这些方法都证明病种带菌.
Production surveys show that diseased rice seeds are likely to be one of the primary sources of primary bacterial leaf blight infection.Several methods of seed testing have been proposed over the years, but they are still not perfect, and there is still some work to be done on disease testing and disinfection Difficulties .In addition, there is no consensus on the disease of seed-borne diseases.Several reports presented here in the study of bacterial blight on rice bacterial blight, using the test methods are: 1 with anti-streptomycin Of the rice bacterial blight pathogen mutant, inoculation of rice stalks at the first flowering stage, after the harvest of the disease species, separated by the disease of this mutant species; 2 Micropipette separation of the pathogen of the glume shell; Back to the test; 4 phage test method after the test seed germination, microscopic examination of seedlings spill over and back for pathogenic identification of these methods have proved disease-borne bacteria.
