“…The AM fungi root colonization in green pepper was reduced by salinity stress regardless of AM fungi inoculation status (Table 2). These findings are in agreement with other researchers working on different vegetable crops, who reported that salinity not only affects the host plant growth but also the AM fungi colonization [2,[6][7][8]. Salinity can reduce AM colonization capacity, spore germination and inhibiting growth of hyphae of the fungus [12,22,23].…”

“…Plant height was significantly higher in AM than nonAM plants regardless of salinity level ( Table 2). The beneficial effects of mycorrhizal fungi on plant growth under saline conditions have been demonstrated in various plant species, by Al-Karaki [4] and Balliu et al [25] in tomato, Zuccarine [26] in lettuce, Pereira et al [18], Kaya et al [7] and Cekic et al [8] in pepper plants.…”

“…The beneficial effects of mycorrhizal fungi on fruit yield and components in green pepper under saline conditions have been demonstrated [7,8,18]. Many studies have indicated that AM fungi contribute to plant growth via enhancement of mineral nutrient uptake particularly that of P and N and hence improve salt tolerance in different vegetable crops grown under saline conditions [2,12,[25][26][27][28][29].…”

“…One of the strategies that have been used to counteract salinity stress involves growing crops that are tolerant to saline conditions [4,5]. However, alleviation of salinity problem using salt tolerant crops is consider expensive and often represents only a temporary solution [6,7]. Therefore, incorporating biological factors that enable plants to tolerate salt stress such as mycorrhizal fungi inoculum would be helpful in improving crop production under saline conditions [6,8].…”

High salinity in soil or irrigation water has detrimental effects on plant nutrition and reduces crop growth and yield. In this study, the effects of pre-inoculation of green pepper (Capsicum annuum L., cv. Zingaro) with arbuscular mycorrhizal (AM) fungi on mineral uptake, growth and fruit yield under irrigation with saline water were investigated. Pepper seedlings were transplanted into nonsterile soil plots under polyethylene covered plastic house conditions and irrigated with saline water of three levels of ECw: nonsaline (0.5; NSW); medium (2.4; SW1) and high (4.8dS m-1; SW2)] salinity levels. At pre-flowering stage (8-weeks after transplanting), AM inoculated plants had greater shoot and root dry matter and plant height than nonAM plants regardless of salinity level. Shoot concentrations and contents of P and K were higher and Na concentration and content were lower in AM compared with nonAM plants at pre-flowering stage. At harvest, fruit fresh yield, fruit weight, and fruit number per plant were higher in AM than nonAM plants. The enhancement in fruit fresh yields due to AM fungi was 38, 42 and 26 % under NSW, SW1 and SW2 treatments, respectively. Results indicate that preinoculation of green pepper transplants with AM fungi improved nutrient uptake and fruit yield especially under moderate rather than severe salinity levels.

“…The result suggests that AMF might play a key role in improving salt resistance of S. physophora under high salt condition and maintaining productivity. The possible reasons are that AMF can help plants uptake water (Porcel et al, 2003) and nutrients (Kaya et al, 2009) from the soil and can decrease the concentration of toxic ions caused by high salt in the soil (Al-Karaki et al, 2001;Mohammad et al, 2003). Moreover, AMF have been shown to increase the activities of antioxidative enzymes (He et al, 2007) and produce plant growth hormones (Iqbal and Ashraf, 2013) that have beneficial effects on plant growth under salt stress.…”

Arbuscular mycorrhizal fungi (AMF) play a key role in plant growth and survival; however, the influence of AMF on the growth and production of Suaedoideae species is still not well understood. The object of this study was to understand the mechanism of AMF that affects the growth of Suaedoideae species under different saline conditions. The result showed that the Suaedoideae species Suaeda physophora was colonized by the AMF species Glomus etunicatum (Ge) and Glomus mosseae (Gm). AMF significantly increased the activities of superoxide dismutase (SOD) and peroxidase (POD) in S. physophora and reduced the concentrations of malondialdehyde (MDA) and H 2 O 2 in the leaves of S. physophora under salt stress. AMF also improved the aboveground biomass of S. physophora and significantly increased its seed numbers. Moreover, AMF increased the aboveground phosphorus (P) content of S. physophora. No significant difference between the effect of AMF species Ge and Gm on S. physophora growth was observed. These results suggest that AMF can increase the salt resistance of the Suaedoideae species S. physophora by increasing SOD and POD activities, reducing MDA and H 2 O 2 concentrations and increasing P uptake. The results highlight that AMF might play an important role in S. physophora growth and population survival under harsh salt conditions.

Although there is evidence for a positive involvement of the antioxidant defense system in plant response to salt stress, there is poor information regarding the influence of mycorrhizal symbiosis on enzymatic and nonenzymatic antioxidant defense in wheat under saline conditions. The present article focuses on the contribution of mycorrhizae to antioxidant defense in salt‐stressed wheat plants. Two wheat (Triticum aestivum L.) cultivars, Sids 1 and Giza 168, were grown under nonsaline or two saline conditions (4.7 and 9.4 dS m–1) with and without arbuscular mycorrhizal fungi (AMF) inoculation. Salt stress considerably decreased root colonization and plant productivity, particularly in Giza 168. Interestingly, mycorrhizal colonization alleviated the adverse effect of salt stress and significantly enhanced plant productivity, especially in Sids 1. The concentration of glycinebetaine, the activities of antioxidative enzymes (superoxide dismutase, peroxidase, catalase, and glutathione reductase) and the concentrations of antioxidant molecules (glutathione and ascorbate) were increased under saline conditions; these increases were more significant in salt‐stressed mycorrhizal plants, especially in Sids 1. Salt stress induced oxidative damage through increased lipid peroxidation, electrolyte leakage, and hydrogen peroxide concentration, particularly in Giza 168. Mycorrhizal colonization altered plant physiology and significantly reduced oxidative damage. Elimination of reactive oxygen species (ROS) can be one of the mechanisms how AMF improve wheat adaptation to saline soils and increase its productivity.
