Chapter 7 Interactions between saprotrophic fungi

摘要: Abstract Fungal competition for resources can be divided into primary and secondary resource capture. With the former have not already been colonized, unlike latter where combat antagonistic mechanisms are used to obtain defend territory. Such interactions mediated: (1) at a distance; (2) following contact hyphal level; or (3) mycelial level. Antagonisms distance level effected by volatile diffusible chemicals including enzymes, toxins other antifungal metabolites. At antagonism is via interference parasitism, which again chemically enzymatically mediated but on more localized scale. Interactions largely studied artificial media with attendant problems of interpretation because large divergence from field conditions, although soil microcosms provided valuable tool between cord-forming fungi; also investigated inoculating pairs saprotrophs directly wood in field. Microcosm field-based knowledge crucial, least role ecosystem functioning, particularly nutrient cycling release, their effects decomposition rates potential as biological control agents.
