Abstracts |
The effect of different levels of salinity (concentrations of NaCl) on growth, nodulation and N2-fixation of single (Rhizobium or AM alone) and dual inoculated (Rhizobium + AM) tree legumes, has been studied in a pot culture experiment using sterilized soil. The parameters growth, nodulation, nitrogen fixation and % AM colonization of roots were considerably influenced with the increase in salt concentration from 0.5 to 4% NaCl. It was observed that the mycorrhizal tree legume (inoculated with the most preferred AM Glomus fasciculatum) performed better in the increasing levels of salinity in comparison to non-mycorrhizal ones. These observations suggested a protective role played by AM in providing resistance to the tree legume against injurious effects of salinity. Inoculation of efficient strain of AM fungi (Glomus fasciculatum) during the course of the study, prevented the injurious effects of salinity in the test plants due to enhanced water and nutrient uptake thereby promoting growth, nodulation and nitrogen fixation of the tree legume under investigation. |
