Present experiments were conducted to assess the response of Panicum turgidum to salinity and possible role of arbuscular mycorrhizal fungi (AMF) in enhancing the salt tolerance. The activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), glutathione reductase (GR) and compatible solutes were increased by salt stress and were further enhanced by AMF inoculation. Hydrogen peroxide and malonaldehyde content increased in salt-stressed plants while a reduction was observed due to AMF inoculation. Salt-stressed plants showed higher activities of pyruvate orthophosphate dikinase (PPDK), phosphoenolpyruvate carboxylase (PEPC) and malate dehydrogenase as compared to control and AMF-inoculated plants. Salt stress caused significant decrease in phosphorous, potassium and calcium uptake but an increase in sodium uptake was observed. AMF alleviate salinity-induced negative impact on the plant growth and nutrient uptake by reducing the oxidative damage through strengthening of the antioxidant system.
