Inter-Radicular Connections of Festuca Rubra and Trifolium Repens
Abstract
Simultaneous evolution of plants with useful rizospheric micro flora has allowed the appearance of symbiotic partnerships between the radicular systems and symbiotical fungi. Natural grasslands represents a stable complex of ecosystems, where the competition capacity of each species is given by the expansion of the root system and branching, in addition to the ability to associate with mycorrhizal fungi. Festuca rubra and Trifolium repens plants were grown in pots, the percentage of each species in the mixture increasing/decreasing by 10 up to 10%. The mycorrhizal circuit was assessed based on the colonization parameters in the root system. For plants with similar proportions in the mixture a strong development of young roots is detected while increasing the association with mycorrhizal fungi. Â The colonization degree decrease is significant only for the high percentages of the specie in the experimental mixture.
