用青枯菌对20个花生品种进行人工接种，研究了青枯菌潜伏侵染对花生根系、根瘤数、生物产量及结实性状的影响。结果表明，青枯菌潜伏侵染对花生生长发育有普遍的抑制作用，不同花生品种对潜伏浸染的反应存在广泛差异。
Twenty peanut varieties were inoculated by R. solanacearum and the effects of latent infection with R. solanacearum on root system, root nodule number, biomass yield and seed setting traits were studied. The results showed that latent infection by R. solanacearum had a general inhibitory effect on the growth and development of peanut. There were wide differences in the response of different peanut varieties to latent infection.
