Abstracts |
Bioaugmentation of Artocarpus chaplasha seedlings was carried out using three native arbuscular mycorrhizal (AM) fungal isolates, viz., Glomus isolate 1 and 2, and Acaulospora scrobiculata. An initial inoculum potential of 12 500 (N) infective propagule per bag with 2 kg substrate was used. Different levels of inoculum (1/4, 1/2, 1, 2 and 4 N) were used along with a control. The inoculum was a mixture of the three native AM fungi. Mature seeds of Artocarpus chaplasha were collected from the natural habitat. Growth parameters such as height, number of leaves, collar diameter and leaf area of the seedlings were measured on the 120th day after transplanting. These growth parameters showed an increasing trend with the increase in inoculum potential. The application of mycorrhizal inoculum resulted in a significant increase in plant height, leaf number and total dry biomass of the test seedlings as compared to the control. Treatments with half the normal inoculum potential showed the highest root-shoot ratio. Seedlings treated with four times the normal inoculum significantly improved the quality by 221% as compared to the uninoculated control. The mycorrhizal inoculation effect ranged between 25.85 and 53.50% for the different levels of inoculum potentials. |
