摘要:
A wide diversity of root morphology and symbiotic associations have been catalogued in 21 tree species in the tropical rain forest of French Guyana. Some unusual structures are described, such as nodular short roots containing hyphal coils. Endomycorrhizal symbiosis prevails in this type of forest. Parasitic nematodes ((Meloidogyne sp) on young seedling roots of Dicorynia guianensis and Peltogyne venosa probably interfere with their regeneration.
