英文摘要 | The agriculture soil in the semi-arid Brazilian Northeast, it finds, in many areas, degraded by the utilization of not sustainable practice. This work proposed to evaluate the effect of increasing NaCl levels in the soils under Spondias tuberosa plants colonized with arbuscular mycorrhizal fungi. Under greenhouse conditions, Spondias seeds were going placed to germinate in trays with mycorrhizal soil and in trays with soil autoclavado. The germination occurred 15 days after the planting and in the 30(th) cultivation day, the plants were going transferred to plastic vases with capacity for 2 L of nutritious solution with the next NaCl doses: 0, 100 and 150 mM. They were monitored the transpiration rate and stomatal conductance until the plants introduced toxicity symptoms to the Na+. After the saline stress suspending, they were evaluated the N, P, K, S, Ca, Mg, Na and Cl contents in the drought matter of the aerial part (stem + leaves) and root. It was going observed the reduction in radicular phytomass and aerial in NaCl first-level regarding the control. Stomatal conductance in plants not micorrizadas was equally reduced. In the root, it was observed significant reductions in Ca, K and Mg contents for the mycorrhizal plants and not mycorrhizal. In the leaves, the increase of NaCl dose induced a substantial reduction in the Ca, Mg and N contents and probably it was caused the reduction in the mass drought production. |
