The present investigation was aimed at determining the effects of vesicular arbuscular mycorrhiza (VAM) on vegetative growth of chrysanthemum var. Marigold plants grown under salinity condition. Entrophospora sp. (VAM) inoculated plants of forty-five days old seedlings (DAS) were transplanted into pots (one seedling per pot) until the flowering. After (75 days) transplanting, seedlings of chrysanthemum var. Marigold were treated with 1.15 (control) 2, 4 and 6 dS/m saline irrigation water and observations showed that whole plant height, number of leaves and branches, N-S and E-W plant spread, leaf area, number of primary and secondary roots, shoot and root length, fresh and dry weight decreased with increasing dose of salinity. Among these treatments, VA mycorrhiza treated plants enhanced vegetative parameters when compared to control plants. VA mycorrhiza promotes salinity tolerance by employing various mechanisms, such as enhancing nutrient acquisition, producing plant growth hormones, improving rhizophoric and soil condition, altering the physiological and biochemical properties of the host. The overall results suggest that mycorrhizal colonization improves host plant mineral concentration and vegetative growth and development of chrysanthemum var. Marigold plants under salinity stress.
