“…There is considerable evidence that arbuscular mycorrhizal fungi can enhance plant growth and vigour under salt stress conditions (Pond et al 1984;Kim and Weber 1985;Pfeiffer and Bloss 1988;Dixon et al 1993;Juniper and Abbott 1993;Tsang and Maun 1999). By contrast, we currently know little about salt resistance of ECM fungi or their potential use in facilitating tree establishment on saline sites.…”

“…was reduced by 50% in this concentration range. When toxicity was assessed by relative biomass production in liquid media, which is regarded as a more accurate measure of toxicity effects than radial growth in agar (Hartley et al 1997), the T. terrestris isolate also showed no growth decrease up to 120 mM NaCl (Dixon et al 1993). Thus, while slight inter-and intraspecific differences were identified among the isolates screened (1-3 isolates per taxon), all appeared broadly resistant to concentrations of NaCl considered toxic to all but the most resistant trees.…”

Influence of salinity on biomass production by Australian Pisolithus spp. isolates

Eighteen isolates, comprising three putative Pisolithus species from eastern and central Australia, were screened for resistance to NaCl during growth in axenic culture. Biomass yield for most isolates showed a decline with increasing NaCl up to 200 mM; however, only five isolates reached an EC 50 point (effective concentration inhibiting growth by 50%) below 200 mM NaCl. Most Pisolithus isolates were thus found to be resistant to NaCl at concentrations found in very saline soils. Of five isolates screened for Na 2 SO 4 resistance, none reached an EC 50 point below 100 mM. While intraspecific variation was evident in the resistance of isolates to both salts, no obvious patterns of interspecific variation were observed. The data thus indicate that isolates of the three Australian Pisolithus species are broadly resistant to salinity and may represent useful ectomycorrhizal inoculants for outplanting of compatible, saltresistant host trees at saline sites.

“…However, the effects of salinity on soil microbionts and their symbiotic relationships with plants are much less investigated. Dixon et al (1993) reported that in vitro growth and in situ symbiosis of ectomycorrhizal fungi generally declined with increasing substrate salinity. However, salt tolerance of the tested fungi varied significantly between species and between isolates within a species.…”

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.

“…Among the biological approaches for enhancing plant growth under saline conditions, the role of AMF has been well established. There is considerable evidence that AMF can enhance plant growth and vigor under conditions of saline stress (Dixon et al, 1993;Juniper and Abbott, 1993;Kim and Weber, 1985;Pfeiffer and Bloss, 1988;Pond et al, 1984;Tsang and Maun, 1999). Most native plants and crops in arid and semi-arid areas are mycorrhizal, and it has been suggested that AM fungal colonization might enhance the salt tolerance of some plants (Tain et al, 2004).…”

A two-staged experiment was conducted to investigate the effects of indigenous and predefined mycorrhizae inoculation on sour orange (Citrus aurantium L.) growth under saline soil conditions. In first stage, indigenous mycorrhizae that existed in the rhizosphere of Mediterranean halophytic plants propagated by using a trap culture method. Trifolium sp. was used as the host plant. In the second stage, the effects of propagated indigenous mycorrhizae and predefined morphological species (Glomus clarum, G. caledonium and G. mosseae) on citrus plant growth were evaluated with high levels of salt (2000 μmhos/cm NaCl) under greenhouse conditions. These species are produced in the method of grafting on a regular basis exists Cukurova University. Andesitic tuff: soil: compost (6:3:1) mixture were used as growth media. Shoot and root dry matter, root infections, spore production, and concentrations of N, P, K, Zn, Mn and Cu in plant tissues were analyzed. The results demonstrated that indigenous mycorrhizae, especially spores extracted from the rhizospheres of Euphorbia paralias and Ambrosia maritima, had a significant effect on citrus growth and nutrient uptake. Citrus plants inoculated with G. clarum and G. caledonium grew more efficiently than those inoculated with G. mosseae.
