An ecological view of the formation of VA mycorrhizas

摘要: In spite of the major advances in understanding functioning symbioses between plants and arbuscular mycorrhizal fungi, details ecology fungi are not well documented. The benefits association related to timing extent colonization roots, differ their contribution plant growth presumably soil aggregation. Knowledge processes that lead successful roots by beneficial at appropriate times for host will form basis guidelines management maximize from symbiosis. Fungi manner which they colonize roots. They also capacity propagules. importance hyphae, spores propagules within living or dead differs among species same different habitats. relationships propagule formation, distribution abundance subsequent mycorrhiza field environments, understood. Methods quantifying especially suitable distinguishing Consequenctly, dynamics seasons, have been little studied. Research is required focuses on as changes soil. Interactions during hyphae sporulation all poorly Without knowledge these processes, it difficult predict likely success inoculation with introduced fungi. Such selecting procedures enhance survival key population. relative tolerance various perturbations surroundings provide a identifying those persist specific environments. influence soils can be identified controlled studies. However, greater emphasis studying mixed populations role played diversity virtually unexplored.
