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.

The objective of this study was to evaluation the efficiency of  Arbuscular mycorrhizal fungi and some species of  Plant growth promoting rhizobacteria (PGPR) to control Fusarium chlamydosporum fungus causing agent of decline date palm off-shoots. The isolation and identification results  showed presence of F. chlamydosporum fungus from infected roots of infected palm trees and its major causing agent of diseases. The results  appeared  Pseudomonas fluorescens , Azotobacter chroococcum and Azosperillium sp. have high antagonism of pathogen under laboratory conditions. The evaluation results of  biocontrol factors Glomus  intraradices, G. mosseae, Gigaspora,  P. fluorescens, A. chroococcum and Azospirillum sp.  indicated that all treatments caused significant reduction in disease  severity of death palm off-shoots disease into13.3-60.0%. compared to control (pathogen only) 86.7%. The interaction between G. intraradices and  P. flourescens  caused significant reduction in disease severity to 13.3% and enhanced the growth of foliage and root of offshoots length to 39.0 and 36.3cm respectively and increased the fresh and dry weight of  foliage and root, 1.7750, 0.4977, 1.764 and  0.339g  this result was closed to Beltanol fungicide effect. Also all biocontrol agents which used in this study alone (without pathogen) enhancement of plant growth  compared with control treatment. The results of the current study showed for the first time that Arbuscular mycorrhizal fungi and Azospirillum sp. Bactrium to control and have good inhibition of Fusarium chlamydosporum fungus causing agent of decline date palm off-shoots and increasing plant growth in Iraq.
