Mycorrhizal Colonization in Atriplex nummularia Lind. Subjected to Desalinizador Reject | Chapter 13 | Advances and Trends in Agricultural Sciences Vol. 2
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.
