Abstract

The effects of systemic infection by Potato virus Y (PVY) and arbuscular mycorrhizal fungus (AMF) Glomus intraradices on host
reaction were quantified in potato symtomatologically, morphologically, serologically, and physiologically. Reduction in plant height and
root development was significantly greater with the AMF+PVY combination than with single PVY infection. Inoculation of AMF increased the symptoms of PVY infection. The G. intraradices x PVY pathosystem significantly increased disease severity and reproduction
of the virus in potato. The chlorophyll contents increased in AMF plants by 18.8% more than the control. The results suggest that the
inoculation of AMF reduced vegetative development in the presence of PVY infection in potato but it increased viral activity considerably.
