Resumo: The search for alternatives that enable the use of saline waters in agriculture has become constant. In this context, the objective was to evaluate the effects of salicylic acid in mitigating salt stress effects on the growth and gas exchange of soursop cv. ‘Morada Nova’. The study was conducted in a greenhouse, in the municipality of Campina Grande - PB, Brazil. Treatments were distributed in randomized blocks, in a 5 x 4 factorial arrangement, corresponding to five levels of electrical conductivity of irrigation water – ECw (0.8; 1.6; 2.4; 3.2 and 4.0 dS m-1) and four concentrations of salicylic acid - SA (0; 1.2; 2.4 and 3.6 mM), with three replicates. Irrigation with saline water compromised the growth and gas exchange of soursop cv. ‘Morada Nova’. However, exogenous application of salicylic acid induced tolerance to salt stress in soursop plants, as their growth, transpiration, stomatal conductance, photosynthesis and instantaneous carboxylation efficiency were favored by the application of salicylic acid, even when exposed to water salinity.

Neste contexto, objetivou-se, avaliar os efeitos do ácido salicílico na mitigação do estresse salino no crescimento e nas trocas gasosas da gravioleira cv. Morada Nova. O estudo foi conduzido em casa de vegetação, no município de Campina Grande - PB. Os tratamentos foram distribuídos em blocos casualizados, em arranjo fatorial 5 x 4, sendo cinco níveis de condutividade elétrica da água de irrigação – CEa (0,8; 1,6; 2,4; 3,2 e 4,0 dS m-1) e quatro concentrações de ácido salicílico – AS (0; 1,2; 2,4 e 3,6 mM), com três repetições. A irrigação com águas salinas comprometeu o crescimento e as trocas gasosas da gravioleira cv. Morada Nova. Entretanto, a aplicação exógena do ácido salicílico induziu a tolerância ao estresse salino a gravioleira, visto que, as plantas tiveram seu crescimento, transpiração, condutância estomática, fotossíntese e eficiência instantânea da carboxilação beneficiadas pela aplicação do ácido salicílico, mesmo quando expostas a salinidade da água.  Universidade Federal Rural do Semi-Árido2020-10-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/927110.1590/1983-21252020v33n424rcREVISTA CAATINGA; Vol. 33 No. 4 (2020); 1092-1101Revista Caatinga; v. 33 n. 4 (2020); 1092-11011983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9271/10376Copyright (c) 2020 Revista Caatingainfo:eu-repo/semantics/openAccessSilva, André Alisson Rodrigues daLima, Geovani Soares deAzevedo, Carlos Alberto Vieira deVeloso, Luana Lucas de Sá AlmeidaGheyi, Hans Raj2023-07-21T16:47:00Zoai:ojs.periodicos.ufersa.edu.br:article/9271Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:47.263745Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
