<p>More than half of Mexican territory is dominated by arid or semi-arid ecosystems. These environments are normally deteriorated by man-induced over-grazing by sheep and goats and the mainly vegetation types are xeric shrublands where thorny plant species are widespread, like catclaw (<em>Mimosa biuncifera </em>Benth., Fabaceae), wich is a nurse plant that promotes plant succession. In this view, the objective of this work was to determine the effect of inoculation with native arbuscular mycorrhizal fungi (AMF) on catclaw seedlings, in order to evaluate plant establishment and their growth under a dry treatment, both in greenhouse and field conditions. Initial question was if the mycorrhization of catclaw increases in a significative way the survival of plant individuals under field conditions. For this, catclaw plants were grown in a greenhouse in Mexico City, with a design consisting of two pot irrigation treatments, wet (W) and dry (D), and two soil treatments: with and without AMF inoculum (M+, M-). Each treatment had 20 repetitions. Weekly: height, mean diameter of coverage, leaf and pinnae number of plant individuals were recorded. After 20 weeks: fresh and dry biomass, relative growth rate, root/shoot ratio, real evapotranspiration, water use efficiency (WUE) and percentage of mycorrhizal colonization were determined. Later, dry treatment (M+ and M-) catclaw individuals were trasplanted to a semi-arid locality at the Mezquital Valley, in Central Mexico and their height, leaf number and survival was recorded monthly during one year. Results show that plants in the wet and mycorrhizal (WM+) treatment had grown higher, had larger plant coverage and had more pinnae than plants in the dry and mycorrhizal (DM+) treatment. Also, the mycorrhizal treatments (W and D) had higher WUE than plants in M-. In field conditions, after one year, survival of M+ plants was greater than witness. It was concluded that mycorrhization of <em>M. biuncifera</em> with native HMA inoculum increases its efficiency in biomass production (higher dry biomass per liter of irrigated water than non mycorrhizal plants) and that favors plant establishment and survival in field conditions. Finally, it could be recommended the AMF inoculation of catclaw plants to be used in revegetation programs of deteriorated semi-arid zones.</p>

The date, the palm tree (Phoenix dactylifera L.) is an important component of arid and semi-arid Mediterranean ecosystems, particularly in Morocco where it plays a considerable socio-economic and ecological role. This species is largely affected by desertification, global warming, and anthropic pressure. Salinity is a very worrying problem that negatively affects the growth and the physiological and biochemical activities of the date palm. In these arid zones, the main challenge is to develop new environmentally friendly technologies that improve crop tolerance to abiotic restraints including salinity. In this sense, Arbuscular mycorrhizal fungi (AMF) have received much attention due to their capability in promoting plant growth and tolerance to abiotic and biotic stresses. It is thus fitting that the current research work was undertaken to evaluate and compare the effects of native AMF on the development of the growth and tolerance of date palm to salt stress along with testing their role as biofertilizers. To achieve this goal, two complexes and two monospecific isolates of native and non-native AMF were used to inoculate date palm seedlings under saline stress (0 g·L−1 Na Cl, 10 g·L−1, and 20 g·L−1 Na Cl). The obtained results showed that salinity drastically affected the physiological parameters and growth of date palm seedlings, whilst the application of selected AMF significantly improved growth parameters and promoted the activities of antioxidant enzymes as a protective strategy. Inoculation with non-native AMF complex and monospecific isolates showed higher responses for all analyzed parameters when compared with the native complex and isolate. It therefore becomes necessary to glamorize the fungal communities associated with date palm for their use in the inoculation of Phoenix dactylifera L. seedlings.

Arbuscular Mycorrhizal Fungal

Arbuscular mycorrhizal fungal communities in northern temperate ecosystems must function during extremes in environmental conditions. However, it is not known if arbuscular mycorrhizal fungi that co-exist in soil communities have similar tolerances to stresses such as drought and freezing. The phenology of arbuscular mycorrhizal fungi was determined over one year in a community in southern Ontario, Canada. Five fungal species from the same community were then used to inoculate five plant species, in all possible combinations, and were subjected to either a freezing treatment or a drought treatment after which new seedlings were transplanted into the treated pots. The percent colonization of roots of each plant species was measured as the difference in mean colonization from the control. Freezing reduced percent colonization in almost every case, whereas drought resulted in both increased and decreased percent colonization. Fungal species responded differently to the treatments, and there was a pronounced plant × fungus effect. These results support the hypothesis that distinct functional groups of arbuscular mycorrhizal fungi exist, and these may determine plant community structure.Key words: arbuscular mycorrhizal fungi, freezing, drying, functional diversity.
