种子携带病菌是个普遍存在的问题,Sinlair(1979年)曾把一粒种子比喻为微生物的一个微观世界,种子内外潜伏着各种真菌、细菌、病毒以及线虫。种传病害的危害性不仅直接威胁受侵染种子的发芽和幼苗生长,而且引起成苗后植物的再侵染和蔓延扩大。此外,种子带菌也能造成仓库种子发热、霉变、腐烂。种子带菌分析是“国际种子检验规程”的一个重要组成部分。种子带菌分析的结果,即其健康度是评价种子质量的重要指标之一。它不仅直接为植物检疫和种子检验服务,而且为选用无病种源提供依据。同时也直接为农业生产进行
Seed-borne pathogens are a pervasive problem. Sinlair (1979) once compared a seed to a microcosm of microorganisms lurking with various fungi, bacteria, viruses and nematodes inside and outside the seed. The harmfulness of seed-borne diseases not only directly threatens the germination and seedling growth of infected seeds, but also causes the re-infection and spread of plants after seedling emergence. In addition, seed-borne bacteria can also cause warehouse seeds fever, mildew, decay. Seed-borne analysis is an important part of the International Seed Inspection Code. The result of seed-borne analysis, that is, its health is one of the important indicators to evaluate the quality of seeds. It not only directly for plant quarantine and seed testing services, but also for the selection of disease-free provenance to provide the basis. At the same time also directly for agricultural production
