在农业生产实践中人们比较重视种子的增产作用,但往往忽视种子还有传播病原和引起种苗病害的作用。本文仅就种子带菌与种苗病害的关系,进行粗浅的分析,目的在于使人们重视种子传播病原物所引起的病害,以便采取恰当的种子处理手段,达到减少种子带菌发病的机会,使因种子带菌引起的种苗病害所造成的损失压缩到最小限度。 1 种子带菌的主要农作物病害水稻主要有4种病害的病原菌是由种子带菌传播的:引起稻瘟病的梨孢菌(Pyricularia oryzae)、胡麻斑病的稻蠕虫菌(Helminthosporiumoryzae)、稻恶苗病的稻串珠镰孢菌(Fusariummoniliforme)、白叶枯病的水稻黄单胞杆菌(Xanthomonas oryzae)。小麦主要有7种
People pay more attention to the stimulation of seed production in agricultural production practice, but often neglect the role of seed in spreading pathogens and causing seedling diseases. This article only on the relationship between seed carrier and seedling diseases, the shallow analysis, the purpose is to make people pay attention to the disease caused by seed-borne pathogens in order to take appropriate means of seed treatment to reduce the incidence of seed-borne diseases, so that the seeds The damage caused by the fungus-borne seedling disease is minimized. 1 main diseases of seed-borne diseases Rice is the main four kinds of pathogenic bacteria are transmitted by seed carriers: Pyricularia oryzae caused by rice blast, Helminthosporiumoryzae, Fusarium moniliforme, and bacterial blight of Xanthomonas oryzae. There are seven main types of wheat
