“…There are numerous studies reporting that mycorrhizal associations lead to crop improvement like growth rate, biomass, and mineral uptake under saline or drought conditions (Augé, 2004;Evelin et al, 2009;Charest, 1998, 1999). Mycorrhizae were shown to have beneficial effects in delaying or coping with toxic effects caused by soil salinity by maintaining an overall physiological balance (Sharifi et al, 2007;Shokri and Maadi ,2009). AM fungi occur naturally in saline environments despite the fact that they have a low affinity with halophyte plants (Khan, 1974).…”

Several environmental factors adversely affect plant growth and development and final yield performance of a crop. Drought, salinity, nutrient imbalances (including mineral toxicities and deficiencies) and extremes of temperature are among the major environmental constraints to crop productivity worldwide. Development of crop plants with stress tolerance, however, requires, among others, knowledge of the physiological mechanisms and genetic controls of the contributing traits at different plant developmental stages. In the past two decades, biotechnology research has provided considerable insights into the mechanism of biotic stress tolerance in plants at the molecular level. Furthermore, different abiotic stress factors may provoke osmotic stress, oxidative stress and protein denaturation in plants, which lead to similar cellular adaptive responses such as accumulation of compatible solutes, induction of stress proteins, and acceleration of reactive oxygen species scavenging systems. Recently, various methods are adapted to improve plant tolerance to salinity injury through either chemical treatments (plant hormones, minerals, amino acids, quaternary ammonium compounds, polyamines and vitamins) or biofertilizers treatments (Asymbiotic nitrogen-fixing bacteria, symbiotic nitrogen-fixing bacteria) or enhanced a process used naturally by plants (mycorrhiza) to minimise the movement of Na+ to the shoot. Proper management of Arbuscular Mycorrhizal Fungi (AMF) has the potential to improve the profitability and sustainability of salt tolerance. In this review article, the discussion is restricted to the mycorrhizal symbiosis and alleviation of salinity stress.

“…Several researchers have found that AMF inoculation/colonization increased the uptake of Zn, Mn, Mg and P in different plant species (Perner et al, 2007;Pasqualini et al, 2007;Cavagnaro, 2008;Ducic et al, 2008;Ducic et al, 2009;Hu et al, 2009;Shokri and Maadi, 2009;Sudova, 2009;Richard et al, 2010;Wu and Zou, 2010). Iron concentration in the leaves of cultivars 'Kothreiki' and 'Chondrolia Chalkidikis' was negatively correlated with AMF abundance (r = -0.49 and -0.79, respectively, data not shown), while those of P in the same two cultivars and Mn in 'Koroneiki' were positively correlated with AMF colonization (r = 0.78, 0.80, and 0.92, respectively, data not shown).…”

“…Such fi ndings occur when AMF applied under natural conditions in the fi eld and in moderate or nutrient rich sites or soils (Orfanoudakis, personal communication). However, the majority of researchers refer that AMF inoculation/colonization infl uenced positively total plant dry weight, as well as other growth parameters of many plant species (Pasqualini et al, 2007;Dag et al, 2009;Sheng et al, 2009;Shokri and Maadi, 2009). Dag et al (2009) refer that the intensity of response in the increases of height and biomass of 12 commercial olive cultivars inoculated with G. mosseae and G. intraradices was highly cultivar-specifi c.…”

“…Apart from the infl uence of AMF on nutrient uptake, other positive aspects of mycorrhization include raise of plant growth (Pasqualini et al, 2007;Dag et al, 2009;Sheng et al, 2009;Shokri and Maadi, 2009), increase of the rate of photosynthesis and transpiration, greater stomatal conductance (Caravaca et al, 2003;Wu and Zou, 2010), enhancement of nursery and post-transplant fi eld response and decrease of transplanting stress (Carretero et al, 2009;Dag et al, 2009), increase of plant tolerance to drought (Marulanda et al, 2007), salt stress (Sheng et al, 2009) and serpentine edaphic stress (Doubkova et al, 2012), as well as protection from nematodes attack (Castillo et al, 2006), improvement of water use effi ciency (Bolandnazar et al, 2007) and amelioration of fruit quality (Nzanza et al, 2012).…”

Rooted leafy cuttings of three Greek olive (Olea europaea L.) cultivars (Koroneiki, Kothreiki and Chondrolia Chalkidikis) were grown for six months in three soil types, in an experimental greenhouse, in order to investigate: i) if their root system was colonized by arbuscular mycorrhiza fungus (AMF) genus and, ii) if genotypic differences concerning growth and mineral nutrition of olive plants existed. Gigaspora sp. colonized the root system of the three cultivars studied, while Glomus sp. colonized only the root system of 'Koroneiki'. Furthermore, in most cases root colonization by AMF differed among cultivars and soil types. The maximum root colonization, in all soils, was found in 'Chondrolia Chalkidikis'. In the three soils studied, the ratio shoot dry weight (SDW)/ root dry weight (RDW) was higher in 'Chondrolia Chalkidikis' than in the other two cultivars. Furthermore, root system morphology of the three olive cultivars was completely different, irrespectively of soil type. Leaf Mn, Fe, Zn, Ca, Mg, K and P concentrations, as well as total per plant nutrient content and nutrient use effi ciency, differed among cultivars under the same soil conditions. These differences concerning root morphology, SDW/RDW, as well as nutrient uptake and use effi ciency, could be possibly ascribed to the differential AMF colonization by Glomus sp. and Gigaspora sp.

“…Colonization with AMF significantly improved dry matter in the salt-stressed plants. This effect of AM fungi on dry matter was more pronounced in aerial biomass than root biomass which may be because of arbuscular mycorrhizal colonization can cause a proportionally greater allocation of carbohydrates to the shoot than root tissues (Shokri and Maadi, 2009). Enhanced growth of mycorrhizal tomato plants grown in saline environments has been related partly to mycorrhiza-mediated enhancement of host plant nutrition (Kaya et al, 2009).…”

The influence of the colonization with arbuscular mycorrhizal (AM) fungus, Glomus mosseae (Nicolson and Gerdemann), on characteristics of growth, osmotic adjustment compounds and activity of antioxidant enzymes in nodules of salt-stressed soybean (Glycine max (L.) Merr.) was studied in this experiment. The pot experiment was arranged as a factorial in randomized complete block design with four replications at greenhouse of College of Agriculture, Tehran University, Iran. Results indicated that the contents of glycine betaine and proline in nodules were higher in inoculated than in noninoculated plants. AM fungal colonization increased the activities of superoxide dismutase, catalase, and peroxidase in the nodules. The results indicate that the AM fungus is capable of alleviating the damage caused by salt stress on symbiotic nitrogen fixation of soybean plants by increasing the accumulation of compatible osmolytes and by increased antioxidant enzyme activity. Consequently, arbuscular mycorrhiza formation highly enhanced the salinity tolerance of soybean plant, which increased symbiotic nitrogen fixation and promoted plant growth. Posledično tvorba arbuskularne mikorize pri soji močno poveča toleranco na slanostni stres s povečano simbiontsko vezavo dušika, kar pospeši rast.
