TLDR
The influences of a vesicular-arbuscular mycorrhiza (Glomus etunicatus) and burrowing nematode (Radophohts similis) alone and in combination on the growth of rough lemon seedlings were studied in the greenhouse.Abstract:
The influences of a vesicular-arbuscular mycorrhiza (Glomus etunicatus) and burrowing nematode (Radophohts similis), alone and in combination, on the growth of rough lemon (Citrus limon) seedlings were studied in the greenhouse. Growth of mycorrhizal seedlings was significantly greater than that of nonmycorrhizal seedlings or seedlings inoculated with R. sindlis. Mycorrhizal stimulation of seedling growth was inhibited by nematode infection. When seedlings were inoculated with G. etunicatus arid R. similis, suppression of seedling growth by R. similis was less on VAM seedlings than on nonmycorrhizal seedlings, Nonmycorrhizal seedlings infected with R. similis were significantly smaller than nonmycorrhizal seedlings free of R. similis. Vesicle formation and mycelia growth were less in nematode-infected roots.read more

Interactions between mycorrhizal fungi and other soil organisms
Alastair Fitter,Jean Garbaye +1 more
TL;DR: Mycorrhizal fungi modify the interactions of plants with other soil organisms, both pathogens, such as root-inhabiting nematodes and fungi, and mutualists, notably nitrogen-fixing bacteria, which are probably important both in natural ecosystems and in agricultural systems.

Nematode parasites of citrus.
Larry W. Duncan,E. Cohn +1 more
TL;DR: There is a tendency at present in the USA and elsewhere to increase early returns by planting higher density orchards with shorter life expectancies due to such diseases as citrus blight, tristeza and greening (Hearn, 1986).

Arbuscular Mycorrhizal Fungi as Potential Bioprotectants Against Plant Pathogens
TL;DR: An overview of mechanisms of interaction between soil-borne plant pathogens and arbuscular mycorhizal (AM) fungi on different plants can be found in this article, where the authors provide an overview of new tools and techniques for the study of microbial interactions in the rhizosphere.

Interactions between migratory endoparasitic nematodes and arbuscular mycorrhizal fungi in perennial crops: A review
TL;DR: In Citrus, Prunus, Malus andCydonia rootstocks, the nematode has shown to have a negative effect over AM colonization in the root, which would seem to be related to mycorrhiza assisted nutrition rather than to a direct suppressive effect of AM over the root-lesion nematodes.
Journal ArticleDOI
Interactions between nematodes and vesicular-arbuscular mycorrhizae
TL;DR: Nematode-mycorrhizal interactions appear to be very specific and highly dependent on the particular association of plant cultivar, fungal and nematode species, the order of colonization by the symbionts and the soil nutrient level.

Advances in the Study of Vesicular-Arbuscular Mycorrhiza
TL;DR: With improved techniques, very striking effects of inoculation on plant growth and phosphate uptake have been demonstrated beyond doubt, and this has led to studies of the uptake mechanism and the source of the extra phosphate.

Nematodes and Forest Trees--Types of Damage to Tree Roots
TL;DR: It is now becoming obvious, particularly in perennial ornamentals and fruit and nut crops, that still greater injury may be caused by nematodes whose presence and damage is less easily measured, and accurate estimates of yield losses of trees due to nematode diseases will be lacking.
