Resumo: The objective of this study was to evaluate, through multivariate data analysis, the effect of exogenous application of hydrogen peroxide on the photosynthetic pigments, gas exchange and growth of soursop seedlings under salt stress. The study was conducted in a greenhouse, at Federal University of Campina Grande - Paraíba. The assay was carried out from May to October 2018. The treatments were distributed in a randomized block design, in a 5 × 5 factorial arrangement, corresponding to five levels of irrigation water electrical conductivity – ECw (0.6-control, 1.2, 1.8, 2.4, and 3.0 dS m-1) and five concentrations of hydrogen peroxide – H2O2 (0, 10, 20, 30, and 40 μM), with two plants per plot and four replicates. Irrigation water salinity from 1.2 dS m-1 negatively affected the biosynthesis of photosynthetic pigments, gas exchange and growth of soursop. Application of hydrogen peroxide at the concentration of 20 μM resulted in attenuation of salt stress effects on the biosynthesis of photosynthetic pigments, gas exchange and growth of soursop. Hydrogen peroxide concentrations above 30 μM intensified the deleterious effect of irrigation water salinity on the photosynthetic pigments, gas exchange and growth of soursop.

O estudo foi conduzido em casa de vegetação, na Universidade Federal de Campina Grande - Paraíba. A pesquisa foi conduzida durante o período de maio a outubro de 2018.  Os tratamentos foram distribuídos em delineamento de blocos casualizados, em arranjo fatorial 5 × 5, sendo cinco níveis de condutividade elétrica da água de irrigação – CEa (0,6 - testemunha, 1,2, 1,8, 2,4 e 3,0 dS m-1) e cinco concentrações de peróxido de hidrogênio – H2O2 (0, 10, 20, 30 e 40 µM), com duas plantas por parcela e quatro repetições. A salinidade da água de irrigação a partir de 1.2 dS m-1 afetou negativamente a biossíntese de pigmentos fotossintéticos, as trocas gasosas e o crescimento da gravioleira. Aplicação de peróxido de hidrogênio na concentração de 20 µM resultou em atenuação do estresse salino sobre a biossíntese de pigmentos fotossintéticos, as trocas gasosas e o crescimento da gravioleira. Concentrações de peróxido de hidrogênio acima de 30 µM intensificaram o efeito deletério da salinidade da água de irrigação sobre os pigmentos fotossintéticos, trocas gasosas e o crescimento da gravioleira.Universidade Federal Rural do Semi-Árido2022-09-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1090610.1590/1983-21252022v35n421rcREVISTA CAATINGA; Vol. 35 No. 4 (2022); 936-944Revista Caatinga; v. 35 n. 4 (2022); 936-9441983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10906/11059Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessSilva, André Alisson Rodrigues daLima, Geovani Soares deAzevedo , Carlos Alberto Vieira deCapitulino, Jessica DayanneGheyi, Hans RajSoares, Lauriane Almeida dos Anjos2023-06-30T18:09:25Zoai:ojs.periodicos.ufersa.edu.br:article/10906Revistahttps://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:2024-04-29T09:46:59.527320Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
