ABSTRACT: The use of brackish water for preparation of nutrient solutions has several impacts on crop performance, depending on the water concentration and cation prevalence. Therefore, this study was conducted to evaluate production and water relations of coriander grown on nutrient solutions prepared with brackish waters with different cationic natures under hydroponic conditions. A randomized block experimental design with four replicates was used, in a 4 × 3 factorial arrangement. The treatments consisted of four electrical conductivities of the nutrient solution (1.6, 3.2, 4.8, and 6.4 dS m-1) which were prepared in waters with different salts (NaCl, CaCl2 .2H2O, and MgCl2 .6H2O). Salinity negatively affected the production and water relations of coriander grown in hydroponicsystem; plants grown on nutritive solutions with predominance of Na+ had higher total dry weight and shoot dry weights, as well as higher stomatal conductance. The largest leaf area was found when using the nutrient solution with predominance of Mg2+.

RESUMO: O uso de águas salobras no preparo de soluções nutritivas tem diferentes impactos no desempenho das culturas, dependendo da concentração e prevalência catiônica da água. Portanto, este estudo foi realizado com o objetivo de avaliar a produção e as relações hídricas do coentro cultivado em soluções nutritivas preparadas com águas salobras de diferentes naturezas catiônicas em condições hidropônicas. O delineamento experimental adotado foi de blocos ao acaso, analisado em esquema fatorial 4 × 3, com quatro repetições. Os tratamentos consistiram de quatro níveis de condutividade elétrica da solução nutritiva (1,6; 3,2; 4,8 e 6,4 dS m-1) que foram preparadas em águas salinizadas com diferentes sais (NaCl; CaCl2 .2H2 O e MgCl2 .6H2 O). A salinidade afetou negativamente a produção e as relações hídricas do coentro cultivado em sistema hidropônico; verificou-se que as plantas submetidas às soluções nutritivas com predominância de Na+ tiveram maior produção de massa seca total e massa seca da parte aérea, bem como maior gs; assim como a maior área foliar foi obtida utilizando solução nutritiva com predominância de Mg2+.
