Beneficial effect of mycorrhiza on nutritional uptake and oxidative balance in pistachio (Pistacia spp.) rootstocks submitted to drought and salinity stress

Environmentally-friendly management techniques such as arbuscular mycorrhizal fungi (AMF) strategies are urgently required to improve plant nutrition and overcome abiotic stress. In this study, we evaluated the influence of symbiotic AMF on four pistachio rootstocks subjected drought (100 % control, 80 %, 60 40 field capacity treatments) salinity (0.91 7.57, 16.12, 24.63 dS/m using NaCl stress for days in two separate experiments. Under both conditions, root shoot dry weights markedly increased AMF-inoculated plants (+M). The accumulation minerals leaves roots (+M) was significantly higher than non-inoculated (-M). improved nutritional status (N, P, Mg2+, Ca2+) genotypes under conditions. Mycorrhizal association decreased Na+ Cl− concentrations stress, hydrogen peroxide (H2O2) methylglyoxal (MG) leaf tissues malondialdehyde (MDA) roots, H2O2 MG MDA were lower those (-M) plants. Sarakhs rootstock accumulated K+, more antioxidants other rootstocks, which could be due its sensitivity Both stresses reduced chlorophyll concentration oxidant content electrolyte leakage from rootstocks. Badami-Riz–e-Zarand UCB1 behaved better terms mineral absorption. Thus, they tolerant respectively. Based these findings, is a sustainable strategy increasing biomass, mineral, Chl contents, decreasing content, thereby enhancing tolerance
