| dc.description.abstract | An investigation was carried out to isolate native AM fungal isolates from the rhizosphere soil of soybean growing areas of Belagavi and Dharwad districts. Further, the forty native AM fungal isolates were screened based on their peroxidase activity and total dry matter accumulation in soybean plant under the restricted water regime of -500 kPa. These experiments were conducted at Weed Control Scheme, MARS and Department of Agricultural Microbiology, University of Agricultural Sciences, Dharwad. A pot culture experiment was laid out in completely randomized design with factorial concept with three irrigation regimes viz., -33 kPa, -500 kPa and -1000 kPa. Moisture was maintained by adding water based on daily evapotraspiration rate. The results of the pot culture studies have revealed that UASDAMFsoybean consortium and UASDAMF consortium significantly increased the stomatal conductance, photosynthetic activity, transpiration rate, PALase activity, ACC deaminase activity, leghaemoglobin content, spore count and per cent root colonization over uninoculated control. Further, UASDAMF consortium and UASDAMFsoybean consortium reduced the leaf temperature, proline (4.94 and 5.35 µmol g-1 FW), glycine betaine content (4.44 and 5.09 µmol g-1 FW), peroxidase activity (3.79 and 4.05 U mg-1 protein) in the plants compared to single inoculants and UIC. The present study has indicated that UASDAMFsoybean consortium and UASDAMF consortium are quite promising in mitigating moisture stress under pot culture studies and also these were found to be efficient in increasing the growth parameters, biomass and nutrient status of soybean plants. Thus, our preliminary findings are indicative of the effectiveness of AMF in protecting plants from water stress and hence can be a promising strategy to develop a biological tool for mitigation of moisture stress. | |
