| dc.description.abstract | The arbuscular mycorrhizal association in Morinda citrifolia was studied under natural conditions using root and rhizosphere soil samples. The results showed 24.87% colonization and 65.70 spores for 50 grams of soil. Totally two AM fungi fungal genera were identified of which 6 belonged to Glomus and 4 belonged to Acaulospora. Glomus was the dominant genera. Then AM fungi Glomus fasiculatum along with Azotobacter chroococcum and Bacillus megaterium were used singly and in combination along with FYM to know the response of Noni seedlings. After inoculation with these PGPRs growth parameters were studied at 30, 40, 60 and 120 DAT and there was a significant increase in the plant height, number of leaves and plant girth in plants inoculated with all three inoculants compared to control. Plant biomass, Nitrogen and Phosphorus concentration were significantly higher in Glomus fasciculatum+ Azotobacter chroococcum + Bacillus megaterium inoculated plants compared to uninoculated plants. Since antioxidant activity of Noni is an important medicinal trait it was estimated and the PGPR inoculated plants showed higher antioxidant activity than uninoculated once. The percent colonization, spore density and PGPR population were also higher in triple inoculated plants. Plants inoculated with only FYM have showed a significant difference in all the plant growth parameters like plant growth, nutrient content and biochemical characters when compared to control. In conclusion the single, dual, and triple inoculated plants showed significant higher in both morphological and biochemical characters. Of all the treatments Glomus fasciculatum + Azotobacter chroococcum + Bacillus megaterium have performed better. | en_US |
