Abstract

Susceptibility of various landscape trees to root-knot nematodes.

Abstract

Young plants of one species of each of 17 genera (Aesculus flava, Ailanthus altissima, Celtis occidentalis, Fagus grandifolia, Ginkgo biloba, Gleditsia triacanthos, Juglans nigra, Koelreuteria paniculata, Liquidambar styraciflua, Maclura pomifera, Magnolia grandiflora, Pyrus calleryana, Robinia pseudoacacia, Sassafras albidum, Sophora japonica, Ulmus parvifolia, Zelkova serrata) and three species each of Betula (B. nigra cv. Heritage, B. platyphylla var. japonica, B. poulifolia) and Prunus (P. avium, P. cerasifera, P. mahaleb) were inoculated with 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, Maclura pomifera, Magnolia grandiflora, Prunus avium, Pyrus calleryana, and Sassafras albidum exhibited a tolerant or resistant response to all of the nematodes.
