英文摘要	Salinity caused by excess salts in soil solutions is one of the most limiting environmental stresses in agriculture worldwide. In this scenario, among strategies that favor the expression of the genetic potential of plants, the use of biostimulants stands out. The objective of this study was to evaluate the influence of a seaweed-based biostimulant on growth, forage production, gas exchange, and accumulation of sodium and potassium ions in pangolao grass (Digitaria pentzii) under saline stress. The experiment was conducted from March to July 2019 using a randomized block design, in a 2 x 3 factorial scheme with two concentrations of biostimulant (0 and 8 mL L-1) and three electrical conductivities of irrigation water (0.03, 2 and 4 dS m(-1)), with four replicates. The accumulation of 50 mu mol g(-1) of sodium in leaves corresponded to a reduction of 0.3 g of dry matter in the leaf blade production per plot. The biostimulant did not influence the structural characteristics, phytomass accumulation, or stomatal conductance of the pangoldo grass, regardless of salinity. At the level of 4 dS m(-1) in irrigation water, the ionic stress toxicity due to the accumulation of salts in the aerial part of pangolao grass was more severe. This is the first evidence of the moderate salinity tolerance of pangolao grass in semi-arid regions.
