Arbuscular mycorrhizal fungi provides enhanced development and reduced mite incidence in Phaseolus vulgaris L. by direct root colonization and via the common mycorrhizal network

Arbuscular mycorrhizal fungi (AMF) are important to agriculture due positive effects on development and resistance attack by herbivores in agricultural crops. AMF can affect a single plant directly colonizing its roots two or more plants through the common network (CMN). This work aimed analyze influence of Phaseolus vulgaris incidence mite Tetranychus urticae bean colonized propagules linked CMN. The root systems were either separated an impassable barrier so that one both could be without forming RMC, they steel mesh allowed outer hyphae colonize non-mycorrhizal other form RMC. infestation occurred first at end experiment all. Percentage colonization, dry mass aerial part roots, number reproductive structures analyzed. colonization MRC positively influenced vegetative P. resulted lower leaflets plants. Therefore, direct AMFs via CMR improves T. infestation.
