The microbial components of the rhizosphere of plant communities recolonizing debris flow deposits of different age were analysed in order to evaluate the modifications of the soil biotic component throughout a progressive plant community dynamic series. Results showed a wide variability of presence within the microbial groups investigated and an antithetic trend between the abundance of nitrogen-fixing bacteria and arbuscular mycorrhizal fungi. The structural complication of the vegetation evolves side by side with the diversification of the rhizospheric flora.

Abstract
The microbial components of the rhizosphere of plant communities recolonizing debris flow deposits of different age were analysed in order to evaluate the modifications of the soil biotic component throughout a progressive plant community dynamic series. Results showed a wide variability of presence within the microbial groups investigated and an antithetic trend between the abundance of nitrogen-fixing bacteria and arbuscular mycorrhizal fungi. The structural complication of the vegetation evolves side by side with the diversification of the rhizospheric flora.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
