Özet:

In natural plant communities are formed fungal-plant associations, associations with the increasing role of the feeding process of both partners, the fungus becoming an extension of the plant's root system, in exchange of carbohydrates synthesized by plants. Mycorrhizal associations are defined by three elements - plant root system, an intraradicular hyphal system and an extraradicular hyphal system. The study of mycorrhizal symbiosis in controlled environments provided by a green house allows the inplementation of a sampling system in different phase of growth and development of symbiotic fungi. Analisys on samples taken were used to explain the frequency and abundance of different structure in emerging or developed the extraroot by vesicular-arbusculare mushrooms Analizele efectuate asupra probelor recoltate au fost utilizate pentru explicarea frecvenţei şi abundenţei cu care apar diferitele structuri intra- sau extraradiculare dezvolatate de către ciupercile vezicular-arbusculare.
