Abstract

 

The present work aims at comparing the effectiveness of native arbuscularmycorrhizal fungi (AMF) inoculum, combined or not with a native endophytic bacteria Pseudomonas fluorescens, originating from saline Algerian arid and semi-arid soils, with a commecial AMF inoculum on Tamarix articulata growth in non-saline (0.6 ds.m-1), moderate saline (2.3 ds.m-1) and saline soils (7.5 ds.m-1). Root mycorrhizal rates were improved by native inoculums more than with the commercial inoculum in saline and moderately saline soils. They were about 4 fold higher with the co-inoculum and by 2 fold with native AMF inoculum. Improvements of shoot biomasses were about 1.4 fold higher with native inoculums as compared to commercial inoculum in moderate saline soil. The positive effect on plant growth of the co-inoculation was associated with shoot phosphorus and nitrogen content enhancements. These findings confirm the capacity of native arbuscular inoculum and of endophytic bacteria to promote the installation of T. articulata plantations in saline soils.

Keywords: Arbuscularmycorrhizal fungi, Tamarix growth, Mycorrhizal inoculum, Soil salinity, Pseudomonas fluorescens.
