Resumo: | Plant parasitic nematodes cause severe agricultural damage in Northeast Brazil. Additionally, soil salinization, especially in the semiarid region of the Northeast, is another factor that limits crop yield. The study evaluated the motility of Meloidogyne enterolobii and Pratylenchus coffeae, and the vertical migration of P. coffeae under saline conditions. Motility was assessed by submitting juveniles of the second stage of M. enterolobii and juveniles and adults of P. coffeae to saline solutions of NaCl, CaCl2, and MgCl2 at concentrations of 0.00, 0.25, 0.50, 0.75, and 1.00 M, and in a mixed solution (combination of the three salts in a 7:2:1 ratio) at 2, 4, 6, and 8 days of exposure. The migration of P. coffeae was studied in segmented columns of 10 cm in length and 4.40 cm in internal diameter, filled with saline soil (mixture of NaCl, CaCl2, and MgCl2) and non-saline, whose evaluations were carried out at 2, 4, and 6 days after soil infestation. The motility and number of active juveniles of both nematodes reduced with increasing saline concentration. From 0.50 M, M. enterolobii activity was not observed in any of the exposure periods to NaCl and CaCl2. The increase in the concentrations of NaCl, CaCl2, and MgCl2 exponentially reduced the number of active P. coffeae, decreasing its activity from 0.75 M. The vertical migration of P. coffeae in the soil was negatively affected by salinity, presenting a more uniform distribution in the non-saline soil. |

Adicionalmente, a salinização do solo, especialmente na região semiárida do Nordeste é outro fator que limita a produtividade das culturas. Avaliou-se nesse estudo, a motilidade de Meloidogyne enterolobii e Pratylenchus coffeae, e, a migração vertical de P. coffeae em um Argissolo Amarelo sob condições salinas. A motilidade foi avaliada pela submissão de juvenis do segundo estádio de M. enterolobii e juvenis e adultos de P. coffeae em soluções salinas de NaCl, CaCl2, MgCl2 nas concentrações de 0,00, 0,25, 0,50, 0,75 e 1,00 M, e em solução mista (combinação entre os três sais na proporção 7:2:1) aos 2, 4, 6 e 8 dias de exposição. A migração de P. coffeae foi estudada em colunas segmentadas de 10 cm de comprimento e 4,40 cm de diâmetro interno, preenchidas com solo salino (mistura de NaCl, CaCl2 e MgCl2) e não salino cujas avaliações foram realizadas aos 2, 4 e 6 dias após a infestação do solo. A motilidade e quantidade de juvenis ativos de ambos nematoides reduziu com o aumento da concentração salina. A partir de 0,50 M não foi observada atividade de M. enterolobii em nenhum dos períodos de exposição a NaCl e CaCl2. O aumento das concentrações de NaCl, CaCl2, MgCl2 reduziu exponencialmente o número de P. coffeae ativos, sessando sua atividade a partir de 0,75 M. A migração vertical de P. coffeae no solo foi negativamente afetada pela salinidade, apresentando distribuição mais uniforme no solo não salino.Universidade Federal Rural do Semi-Árido2022-09-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1033210.1590/1983-21252022v35n414rcREVISTA CAATINGA; Vol. 35 No. 4 (2022); 865-876Revista Caatinga; v. 35 n. 4 (2022); 865-8761983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10332/11052Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccess Silva, Ivis Andrei Campos ePedrosa, Elvira Maria Regis Silva, Enio Farias de França eRolim, Mario Monteiro Vicente, Thais Fernanda da Silva 2023-06-30T18:02:07Zoai:ojs.periodicos.ufersa.edu.br:article/10332Revistahttps://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:2024-04-29T09:46:56.217269Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
