Füzy A., B. Bíró, and T. Tóth. 2003. Plant-microbe relationshiips and correlation with several soil properties in Hungarian salt-affecteds soils. (Hung.). Természetvédelmi Közlemények. 10:207-216 The interactions between the microbial and soil characteristics were analysed in the rhizosphere of dominant halophytes (Plantago maritima, Aster tripolium and Puccinellia limosa) at two salt effected regions in Hungary. Beside the quality and the concentration of salt specific anions, the pH values and some other soil physical parameters of soil were regularly determined on the sites. The abundance of the most important culturable microorganisms and the colonisation values of arbuscular mycorrhizal fungi (AMF) were also assessed in the mycorhizosphere of the halophytes investigated. Results have shown, that microbial parameters of the rhizosphere are rather sensitive indicators of the stress conditions. The abundance of benficial microorganisms investigated in the rhizosphere of the halophytes was found to be more stable indicator, suggesting the high dependence of host plants among the stress conditions. Number of colony forming units of fungi on the other hand have decreased significantly with the higher pH values. Arbuscular richness of the mycorrhiza colonised root indicated the functioning of the plant-mycorrhiza-soil systems and was found a sensitive variable as a function of environmental stress factors. Water flooding and the permanent anthropogenic disturbance could have detectable influence on the soil- plant-microbe interactions at the salt affected areas.
