Resumo: | Brazil is currently the world’s largest producer and exporter of sugarcane, and the crop has high socioeconomic importance in the country. Root-knot nematodes (Meloidogyne spp.) are one of the major limiting factors in sugarcane production. These plant parasites have wide geographic distribution, high damage potential, and are difficult to control. Recently, the species Meloidogyne enterolobii was identified in sugarcane crops in the state of Pernambuco, Brazil. Given the importance of genetic resistance for integrated nematode management and the lack of research on the M. enterolobii–sugarcane pathosystem, this study aimed to assess the response of sugarcane cultivars to M. enterolobii. Thirteen cultivars were evaluated for their resistance to M. enterolobii based on the nematode reproduction factor. The experiment was conducted in a greenhouse, in a completely randomized design, with 14 replicates. Pre-sprouted sugarcane seedlings were transplanted to 5 L pots, and each pot was considered an experimental unit. At 15 days after transplanting, the seedlings were inoculated with 5,000 eggs and second-stage juveniles of M. enterolobii. Tomato and okra plants were also inoculated to test the viability of the inoculum. At 240 days after inoculation, plant roots were processed and evaluated for nematode number. This parameter was used to calculate the nematode reproduction factor on each cultivar. All sugarcane cultivars were found to be immune to M. enterolobii, with a reproduction factor of 0. |

Dentre os diversos fatores que podem afetar sua produção se destacam os nematoides de galha (Meloidogyne spp.), por apresentarem ampla distribuição geográfica, alto potencial danoso e difícil controle. Recentemente a espécie Meloidogyne enterolobii foi identificada parasitando a cultura da cana-de-açúcar em Pernambuco. Dada à importância da resistência genética no manejo integrado de fitonematoides e a falta de trabalhos envolvendo o estudo desta espécie na cultura, o presente trabalho teve como objetivo avaliar a resposta de cultivares de cana-de-açúcar a M. enterolobii. Foram avaliadas 13 cultivares quanto a sua resistência a esta espécie com base no fator de reprodução do nematoide. O experimento foi conduzido em delineamento inteiramente casualizado, com 14 repetições, e mantido em casa de vegetação. Foram utilizadas mudas pré-brotadas de cana-de-açúcar, transplantadas para vasos de 5L, sendo cada vaso considerado uma unidade experimental. Cada unidade experimental foi inoculada com 5.000 ovos e juvenis de segundo estádio de M. enterolobii 15 dias após os transplantio. Plantas de tomateiro e quiabeiro também foram inoculadas para atestar a viabilidade do inoculo utilizado no experimento. Decorridos 240 dias da inoculação as raízes foram processadas para obtenção da população final e cálculo do fator de reprodução do nematoide de cada tratamento. Todas as cultivares de cana-de-açúcar avaliadas foram resistentes/imunes à M, enterolobii, apresentando fator de reprodução igual a zero.EDUFU2020-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4797210.14393/BJ-v36n6a2020-47972Bioscience Journal ; Vol. 36 No. 6 (2020): Nov./Dec.; 1984-1989Bioscience Journal ; v. 36 n. 6 (2020): Nov./Dec.; 1984-19891981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/47972/30400Brazil; Contemporary Copyright (c) 2020 Gabriela Silva Thomazelli, Roberta Luiza Vidal, Lúcio Roberto Vizentini, Daniel Dalvan do Nascimento, Renato Silva Soares, Alexandre Fameli Mammana, Rivanildo Junior Ferreira, Pedro Luiz Martins Soareshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessThomazelli, Gabriela SilvaVidal, Roberta LuizaVizentini, Lúcio RobertoNascimento, Daniel Dalvan do Soares, Renato SilvaMammana, Alexandre FameliFerreira, Rivanildo JuniorSoares, Pedro Luiz Martins2022-05-30T18:09:55Zoai:ojs.www.seer.ufu.br:article/47972Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-05-30T18:09:55Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
