Resumo: This study was carried out with the objective of evaluating the water relations, photosynthetic pigments and growth of passion fruit cv. BRS Rubi do Cerrado, as a function of the cationic nature of irrigation water and exogenous application of hydrogen peroxide. The experiment was carried out under greenhouse conditions in Pombal – PB, Brazil. The experimental design was randomized blocks, in a 6 × 4 factorial scheme, corresponding to six cationic nature of water - CNW (S1 - Control; S2 - Na+; S3 - Ca2+; S4 - Na++Ca2+; S5 - Mg2+ and S6 - Na++Ca2++Mg2+) and four concentrations of hydrogen peroxide - H2O2 (0, 20, 40 and 60 μM), distributed in a randomized block design with four replicates. Plants in the control treatment (S1) were irrigated using water with electrical conductivity (ECw) of 0.3 dS m-1, while those of the other treatments (S2; S3; S4; S5 and S6) were subjected to ECw of 3.0 dS m-1, prepared with different cation(s). Application of 60 μM of H2O2 reduced the percentage of intercellular electrolyte leakage in plants irrigated with water of calcic composition. Salinity of water composed of sodium, sodium+calcium and sodium+calcium+magnesium, and H2O2 concentrations of 40 and 60 μM resulted in lower leaf water potential. The biomass accumulation of passion fruit was more sensitive to the variation of the electrical conductivity of the water. Regardless of the cationic nature, the use of water with electrical conductivity of 3.0 dS m-1 produced passion fruit seedlings with  a Dickson quality index higher than 0.2, considered acceptable.

BRS Rubi do Cerrado, em função da natureza catiônica da água de irrigação e aplicação exógena de peróxido de hidrogênio. O experimento foi desenvolvido em condições de casa de vegetação em Pombal - PB. O delineamento experimental foi o de blocos casualizados, em esquema fatorial 6 × 4, sendo seis natureza catiônica da água - NCA (S1 -Testemunha; S2 - Na+; S3 - Ca2+; S4 - Na++Ca2+; S5 - Mg2+ e S6 - Na++Ca2++Mg2+) e quatro concentrações de peróxido de hidrogênio – H2O2 (0, 20, 40 e 60 µM), distribuídos em delineamento de blocos ao acaso com quatro repetições. As plantas do tratamento testemunha (S1) foram irrigadas com água de condutividade elétrica (CEa) de 0,3 dS m-1, e os demais tratamentos (S2; S3; S4; S5 e S6) foram submetidos à CEa de 3,0 dS m-1, preparada com diferente(s) cátion(s). Aplicação de 60 µM de H2O2 diminuiu a percentagem de extravasamento de eletrólitos nas plantas irrigadas com água de composição cálcica. A salinidade da água constituída de sódio, sódio+cálcio e sódio+cálcio+magnésio e concentrações de 40 e 60 µM de H2O2 resultou em menor potencial hídrico foliar. O acúmulo de fitomassas do maracujazeiro foi mais sensível à variação da condutividade elétrica da água. Independente da natureza catiônica, o uso de água com condutividade elétrica de 3,0 dS m-1 produziu mudas de maracujazeiro com índice de qualidade de Dickson superior a 0,2 considerado aceitável.Universidade Federal Rural do Semi-Árido2021-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/933110.1590/1983-21252021v34n418rcREVISTA CAATINGA; Vol. 34 No. 4 (2021); 904-915Revista Caatinga; v. 34 n. 4 (2021); 904-9151983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9331/10753Copyright (c) 2021 Revista Caatingainfo:eu-repo/semantics/openAccessLima, Geovani Soares deSouza, Weslley Bruno Belo de Pinheiro, Francisco Wesley AlvesSoares , Lauriane Almeida dos Anjos Gheyi, Hans Raj 2023-07-04T13:45:46Zoai:ojs.periodicos.ufersa.edu.br:article/9331Revistahttps://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:2024-04-29T09:46:47.933226Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
