Influence of arbuscular mycorrhizae on yield, nutrients, organic solutes, and antioxidant enzymes of two wheat cultivars under salt stress

Abstract

The efficacy of arbuscular mycorrhizae (AM) on nutrients, organic solutes, and antioxidant enzymes of wheat under salt stress was investigated and related to root colonization and plant productivity. The mycorrhizal inoculation increased N, P, K, Ca, and Mg uptake, soluble sugars, free amino acids, and proline accumulation, as well as peroxidase and catalase activities under saline conditions as compared to nonmycorrhizal plants. On the other hand, Na concentration was lower in mycorrhizal than in nonmycorrhizal plants grown under saline conditions. Arbuscular mycorrhizae protected wheat against the detrimental effects of salinity and stimulated its productivity. Hence, mycorrhizal colonization can play a vital role in the mitigation of the adverse effects of salinity by improving the wheat osmotic adjustment response, enhancing its defense system, and alleviating oxidative damage to cells. Arbuscular mycorrhizae are able to alter plant physiology in a way that empowers the plant to grow more efficiently on salt‐affected lands.

Salinity Stress and Arbuscular Mycorrhizal Symbiosis in Plants

“…Türkan and Demiral (2009) have reported the tremendous link between antioxidant capacity and salinity tolerance. Studies reveal that mycorrhizal symbiosis enables the host plant to survive under salt or water deficit stresses by enhancing the production of various antioxidant enzymes (Zhong Qun et al 2007;Ruíz-Sánchez et al 2010;Talaat and Shawky 2011). Manchanda and Garg (2011) also reported that POX and CAT activity enhances salt tolerance in C. cajan (Mehdy 1994).…”

Diversity of Arbuscular Mycorrhizal Fungi of Durum Wheat (Triticum durum Desf.) Fields of the East of Algeria

“…In research, several approaches are used for improving wheat production including AMF which are the principal symbiotic components of the soil edaphon and account for 25% of the biomass of the soil micro-fauna (Hamel, 1996). Indeed, wheat is easily mycorrhized by AMF under controlled greenhouse conditions and under field conditions (Cade-Menun et al, 1991;Neveen & Bahaa, 2011). These fungi have many advantages on the ecological level as well as the economic level, they establish symbiotic associations with plant roots, thus allowing the improvement of the agricultural products yield, and they translocate water and mineral nutrients such as phosphorus and nitrogen to the plants (Hu et al, 2010;Neveen & Bahaa, 2011).They positively affect plants tolerance to both abiotic (soil salinity and drought) as well as biotic (pathogens) stresses (Allen & Boosalis, 1983;Strullu et al, 1991).…”

Efecto de Glomus fasciculatum y su relación con tres abonos orgánicos en dos cultivares de haba

“…Singh et al (2013) reported 71% colonization by combining G. fasciculatum and G. monteilii in Coleus forskohlii and with G. fasciculatum this was 65%. In another study the addition of G. fasciculatum resulted in an increase in N, P. K, Ca, and Mg, soluble sugars, free amino acids, proline accumulation and presence of a peroxidase and catalase in saline conditions with wheat (Talaat and Shawky , 2011). Moreover sucrose increased in citrus by applying Funneliformis masseae (Wu et al, 2013).…”
