摘要: The results of analyses the distribution, structure and function ericoid, ecto vesicular-arbuscular mycorrhizas are used to challenge conventional view, which was based largely upon studies isolated plants excised plant roots under controlled conditions, that symbiosis is primarily involved in capture phosphate ions. In nature, each mycorrhizal type associated with an ecosystem soil environment distinctive characteristics selection has favoured development a particular range attributes. These attributes evaluated their importance for individual ecosystems they occur assessed. It concluded knowledge full functions essential understanding distribution dynamics it predominates.
