Resumen

Urochloa brizantha  and Megathyrsus maximus  grasses are species that are not very tolerant to salinity and that plant hormones are fundamental for the adaptation of plants to salinity, as they mediate several adaptive responses; the present work aims to evaluate the effect of auxin, indoleacetic acid, on the mechanisms of adaptation to salt stress. On the day of collection, the groups of plants were divided into leaves, stems and roots to estimate the contents of Na+  and K+ ions. The quantification of ions in these samples was done by flame photometry. Treatment with auxin did not stimulate the regulatory mechanisms of Na+ homeostasis in U species. brizantha and M. maximus.
