Resumo: | Plant-parasitic nematodes are among the main pathogens that cause disease and damage to crops, causing serious agricultural damage worldwide. However, another limiting factor for agricultural production, especially in the semiarid region of northeastern Brazil, is the salinization of soils caused by natural or man-made factors. Although there are studies related to the interaction of soil texture, temperature and capture in the movement of plant parasites, information on the behavior of these parasites in saline environments is scarce. Thus, the present study aimed to evaluate the motility of Meloidogyne enterolobii and Pratylenchus coffeae and the vertical migration of P. coffeae in saline environments. Motility was evaluated by submitting juveniles and adults of M. enterolobii and P. coffeae in saline solutions of NaCl, CaCl2, MgCl2 with concentrations of 0.0 (control with distilled water), 0.25; 0.5; 0.75 and 1M, 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 soil columns, 10 cm long, and with an internal diameter of 4.4 cm, filled with saline soil (mixture of NaCl, CaCl2, MgCl2) and non-saline soil, and the evaluations were performed at 2, 4 and 6 days after inoculation.The increase in the salt concentrations of all the evaluated salts reduced the motility of both nematodes. The vertical migration of P. coffeae was negatively affected by soil salinity. |

Contudo, outro fator limitante para a produção agrícola, em especial na região semiárida do Nordeste brasileiro, é a salinização dos solos causada por fatores naturais ou antrópicos. Embora já existam estudos relacionados à interação da textura, temperatura e umidade do solo na movimentação de nematoides parasitas de plantas, informações sobre o comportamento desses parasitas em ambientes salinos são escassas. Dessa forma, o presente estudo teve como objetivos avaliar a motilidade de Meloidogyne enterolobii e Pratylenchus coffeae e migração vertical de P. coffeae em meios salinos. A motilidade foi avaliada submetendo juvenis e adultos de M. enterolobii e P. coffeae em soluções salinas de NaCl, CaCl2, MgCl2 nas concentrações de 0,0 (controle com água destilada), 0,25; 0,5; 0,75 e 1 M, e em e 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 4,4 cm de diâmetro interno, preenchidas com solo salino (mistura de NaCl, CaCl2 e MgCl2) e não salino, e as avaliações realizadas aos 2, 4 e 6 dias após a inoculação. O aumento das concentrações salinas de todos os sais avaliados promoveu redução na motilidade de ambos os nematoides. A migração vertical de P. coffeae foi negativamente afetada pela salinidade do solo.Submitted by (ana.araujo@ufrpe.br) on 2023-06-16T15:36:21Z No. of bitstreams: 1 Ivis Andrei Campos e Silva.pdf: 1188689 bytes, checksum: f615286b49d1892195c3a6b313fbf63b (MD5)Made available in DSpace on 2023-06-16T15:36:21Z (GMT).

Plant-parasitic nematodes are among the main pathogens that cause disease and damage to crops, causing serious agricultural damage worldwide.

Although there are studies related to the interaction of soil texture, temperature and capture in the movement of plant parasites, information on the behavior of these parasites in saline environments is scarce. Thus, the present study aimed to evaluate the motility of Meloidogyne enterolobii and Pratylenchus coffeae and the vertical migration of P. coffeae in saline environments. Motility was evaluated by submitting juveniles and adults of M. enterolobii and P. coffeae in saline solutions of NaCl, CaCl2, MgCl2 with concentrations of 0.0 (control with distilled water), 0.25; 0.5; 0.75 and 1M, 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 soil columns, 10 cm long, and with an internal diameter of 4.4 cm, filled with saline soil (mixture of NaCl, CaCl2, MgCl2) and non-saline soil, and the evaluations were performed at 2, 4 and 6 days after inoculation.The increase in the salt concentrations of all the evaluated salts reduced the motility of both nematodes. The vertical migration of P. coffeae was negatively affected by soil salinity. |
