Mycorrhizal Colonization in Atriplex nummularia Lind. Subjected to Desalinizador Reject

This work has the objective of evaluating the mycorrhizal colonization of Arbuscular Mycorrhizal
Fungus - AMF Claroideoglomus etunicatum in Atriplex nummularia Lind. subjected to desalinator
reject. The experiment was conducted in a greenhouse at the headquarters of Agronomic Institute of
Pernambuco - IPA, Recife, Pernambuco, Brazil. The experimental design was randomized blocks
with the treatments constituted in a factorial scheme of five levels of salinity in AC= 2.86 mS/cm; T1=
11.54 mS/cm; T2= 12.04 mS/cm; T3= 13.13 mS/cm and T4= 14.16 mS/cm, associated with the
presence and absence of fungus, presence and absence of nutrient solution, and autoclaved and
non-autoclaved soil. 8.0 g of Hoagland & Arnon complete nutrient solution was added every fortnight.
After five months, the roots of the treatments were collected and the root colonization was evaluated.
It was found that in all treatments the association between Claroideoglomus etunicatum and Atriplex
nummularia was beneficial. The correlation was positive for the treatment T4 (Reject + 14 gNaCl) +
AMF. Thus, it was observed that salinity had no negative effect on the association as well as on the
growth of the vegetable.
