Analysis of the Atriplex Subjected to Claroideoglomus etunicatum and to the Desalinator Reject

Abstract

The objective of this work was to analyze the minerals extracted from the soil and absorbed by Atriplex nummularia Lind. submitted to Claroideoglomus etunicatum and to the desalinator reject. The experiment was conducted in a greenhouse at the Agronomic Institute of Pernambuco - IPA, Recife, Pernambuco, Brazil. The experimental design was of randomized blocks with the treatments constituted in a factorial scheme, in five levels of salinity: AC: 2.87 mS / cm; T1: 11.54 mS / cm; T2: 12.04 mS / cm; T3: 13,13 and T4: 14,16 mS / cm, associated with the presence and absence of AMF, presence and absence of nutrient solution and autoclaved and non-autoclaved soil. 8.0 ml of Hoagland & Arnon complete nutrient solution was added every fortnight. After five months, the contents of the elements absorbed by the plant and present in the soil were evaluated. It was observed that in non-autoclaved soil Atriplex absorbed higher nutrient content. Furthermore, the best treatment was the T4 of EC of 14.16 mS/cm + AMF + Hoagland & Arnon solution. Therefore, the high sodium content absorbed (22%) by Atriplex evidences the potential of its use in phytoextraction programs in soils affected by salts.

Caracterización de frutos tomate (Solanum lycopersicum) en plantas colonizadas por el hongo micorrízico arbuscular Rhizopagus irregularis en condiciones de estrés salino

“…Varios estudios han demostrado que la inoculación con HMA mejora el crecimiento y la productividad bajo estrés salino (Sannazzaro et al, 2006). Existen pruebas de que los HMA mejoran la capacidad de las plantas para hacer frente al estrés salino al mejorar la absorción de nutrientes, la actividad fotosintética, el equilibrio iónico y el uso eficiente del agua, así como estimular la actividad de las enzimas protectoras al estrés en plantas micorrizadas (De Melo et al, 2019;Sheng et al, 2008). Los HMA son biomejoradores importantes para suelos salinos, ya que la colonización micorrízica arbuscular mejora el crecimiento, nutrición y vigor de la planta y mitiga el daño en las plantas hospederas causado por la salinización del suelo (Evelin et al, 2012).…”

Use of the Moringa oleifera Seeds Fixed-bed Model and Pernambuco Semi-arid Desalinator Reject

“…Given this situation, it is essential to treat and reuse this water, the only one available in the region, so that an improvement in the quality of life of this population is promoted [2,3].…”
