An investigation was carried out for twenty-two plant species, cultivated widely as vegetable crops in arid region of Rajasthan,
state of India belonged to eight different families to measure their affinity in harbouring symbiotic association with arbuscular
mycorrhizal fungi (AM fungi) and nutrient status in rhizospheric soil. Twenty out of the twenty two species were having developed
AM fungal colonization in their root tissues with a range of 16.33% to 91.33%. All the soil samples tested were slightly acidic to
alkaline and housed AM fungal spore with a density ranges from 80.33-199 spores/ 50g air dried soil. The AM fungal spore density
in the soil was not found to have any effect on symbiotic colonization in root tissues of studied vegetable crop plants by Mycorrhizae.
The soil chemical analysis was also noticed to have no correlation with both colonization of root tissues by AM fungi and spore
densities in the rhizospheric soil. Variations in AM fungal root colonization’s and spore densities were found statistically significant.
Plant species had a significant role in root tissue colonization by AM fungi.
