Effects of Arbuscular Mycorrhizal Inoculation by Indigenous Fungal Complexes on the Morpho-Physiological Behavior of Argania spinosa Subjected to Water Deficit Stress

Our objective is to test selected mycorrhizal complexes verify the contribution of symbiosis as a biological tool promoting development argan tree under hostile conditions. In addition, this study aims assess impact soil drought caused by stopping watering young plants inoculated with strains fungal indigenous species in comparison non-inoculated plants. Under conditions water deficit stress, most marked reductions fresh and dry biomass were recorded non-mycorrhizal The negative values leaf potential Ψf Ψb also noted On other hand, Bouyzakarne inoculum relatively less affected discontinuation compared those Argana inoculum. Water stress reduction potassium phosphorus content leaves roots all However, exhibited highest P K ones. Therefore, mycorrhization compensates for absorption inorganic nutrients during drought. Sodium gradually decreased but increased roots, delocalization Na+ ions resulted higher concentrations than lower root controls. reduced chlorophyll b a/b ratio stressed lowest levels proline soluble sugars plants, especially extension duration stress. accumulation was superiority complex that Argana. contrast, We concluded correct choice symbiotic fungi complexes, AMF inoculation biotechnology can benefit cultivation, stressful arid regions structural drought, where native Arbuscular are low.
