Abstract: Young plants of one species of each of 17 genera (Aesculus, Ailanthus, Celtis, Fagus, Ginkgo, Gleditsia, Juglans, Koelreuteria, Liquidambar, Madura, Magnolia, Pyrus, Robinia, Sassafras, Sophora, Ulmus, Zelkova) and three species each of Betula and Prunus were inoculated with the four common root-knot nematodes (Meloidogyne spp.). Of 23 tree species tested, the majority were susceptible to one or more of the nematodes but Ailanthus altissima, Fagus grandifolia, Gleditsia triacanthos, Juglans nigra, Liquidambar styraciflua, Madura pomifera, Magnolia grandiflora, Prunus avium, Pyrus calleryana, and Sassafras albidum exhibited a tolerant or resistant response to all of the nematodes.
