| 摘 要： | 1982~1984年研究结果,广东水稻瘤矮病毒田间的自然越冬寄主植物主要是再生稻、自生稻,带毒率分别为63.95~100%和28.57~41.20%;还新发现看麦娘(Alopecurus aequulis)是越冬寄主植物,但只个别株发病,故不重要。人工接种成功的寄主植物还有小麦(Triticum aestivum)、燕麦(Arena sativa)、野生稻(Oryza rufipogon)和玉米(Zea mays)。玉米是本研究接种成功的新寄主。稗草(Echinochloa crus-gallis)和李氏禾(Leersia hexandra)不受侵染。在自然情况下,迄未发现越冬的小麦和野生稻有感染此病的。

| Abstract: | Investigations carried out in 1982-1984 revealed that in the epidemic regions the rice ratoon and the volunteer rice plants were the most important overwintering host plants of the rice gall dwarf virus with disease incidence of 63.95-100% and 28.57-41.20% respectively.Alopecurus aequalis was found to be a new overwintering host plant,but it was found to be infected naturally only once,so it was probably not too important. |
