The effects were investigated, under controlled conditions, of single and joint inoculation of olive planting stocks cvs Arbequina and Picual with the arbuscular mycorrhizal fungi (AMF)
Glomus intraradices, Glomus mosseae or Glomus
viscosum, and the root-knot nematodes
Meloidogyne incognita and Meloidogyne javanica, on plant performance and nematode infection. Establishment of the fungal symbiosis significantly increased growth of olive plants by 88·9% within a range of 11·9–214·0%, irrespective of olive cultivar, plant age and infection by M. incognita or M. javanica. In plants free from AMF, infection by Meloidogyne
spp. significantly reduced the p...
