众所周知许多植物病毒能通过感病植物种子传播,已知的种传植物病毒总数逐年增加。Fullton 列举大约有36种病毒通过63种植物传播;Eennett 和 Shepherd 扩大到列举有50种种传病毒;Phatak 列举85种病毒通过一种或多种寄主种子传播。种子传毒可能是病毒在一种作物上由一个生长季传到下一个生长季的最重要的途径,也是病毒接种介体最初的毒源。某种作物种子将病毒带到一个地区,在该地区如有有效的介体,则会进一步
It is well known that many plant viruses can be transmitted through the seeds of susceptible plants, and the total number of known plant-borne virus has increased year by year. Fullton lists about 36 viruses spread through 63 species of plants; Eennett and Shepherd expand to enumerate 50 species of viruses; and Phatak lists 85 viruses that are transmitted through one or more host species. Seed-borne virus may be the most important route by which a virus passes from one growing season to another during a growing season and is also the initial source of virus-inoculum. A crop seed will take the virus to a region where further effective mediators are available
