Resumo: | ABSTRACT: The objective of this study was to evaluate the physiological and biochemical mechanisms of adaptation of Hyptis suaveolens under osmotic stress due to salinity inoculations with a mycorrhizal fungal species. H. suaveolens seeds were germinated in polyethylene pots containing a substrate associated with or without arbuscular mycorrhizal fungi (AMF). After plant formation, treatments were treated with different salt concentrations (0.0, 35, 70, and 105 mM) and fungi (control and two types of AMF), totaling 12 treatments with three replicates. The experimental design used randomized blocks in a 4 x 3 factorial scheme, totaling 12 treatments with three replicates each. Salinity affected all measured physiological and biochemical variables, and the stress reduced dry matter content. Plants associated with AMF had increased dry matter compared to non-associated plants, and there were increased biochemical and physiological responses of AMF-colonized plants in the 35 mM NaCl treatment. However, saline stress negatively affected the development of H. suaveolens; and therefore, no attenuation of fungi was observed.
