Resumo: | http://dx.doi.org/10.5902/1980509812340Teak (Tectona grandis) is originated from Asia, and was introduced in the state of Mato Grosso, Brazil, inthe decade of 1970. The analysis of roots collected from Nova Maringá, Mato Grosso state, revealed thepresence of the nematode Meloidogyne javanica,that was confirmed by morphometric perineal features offemales. The females were extracted from egg masses of teak roots and the nematode was maintained intomato plants. Because no information is available about this pathosystem, the objective of this study wasto evaluate the pathogenicity of Meloidogyne javanica on teak plants. This study showed, that in controlledconditions, teak is a susceptible host to the nematode because the reproduction factor (Pf =final populationof nematodes/ Pi) varied from 2.6 to 27. Moreover, the nematode is a teak plant pathogen, because theplants exhibited pronounced symptoms of nutrients deficiency. |

Em uma análise de raízes da planta de teca, coletada no município de Nova Maringá, MT, foi revelada a presença do nematoide Meloidogyne javanica, a qual foi confirmada pelas características morfológicas da estrutura perineal da fêmea. Massas de ovos foram extraídas de raízes de teca e transferidas para plantas de tomateiro para manutenção da população. Como não havia informações disponíveis sobre esse patossistema, dois trabalhos foram instalados com o objetivo de avaliar a patogenicidade de Meloidogyne javanica sobre plantas de teca. Constatou-se que a teca comportou-se como hospedeira suscetível do nematoide, pois o fator de reprodução (Pf = população final do nematoide/população inicial) variou de 2,6 a 27. Além disso, agressivo, pois as plantas exibiram severo sintoma de deficiência nutricional. No entanto, em condições controladas, não houve diferença significativa em relação ao nível populacional do nematoide e o desenvolvimento das plantas.Universidade Federal de Santa Maria2013-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1234010.5902/1980509812340Ciência Florestal; Vol. 23 No. 4 (2013); 563-569Ciência Florestal; v. 23 n. 4 (2013); 563-5691980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/12340/7801Oliveira, Anmyna Soraia deSilva, Rosangela Aparecida dainfo:eu-repo/semantics/openAccess2017-04-17T11:14:42Zoai:ojs.pkp.sfu.ca:article/12340Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-17T11:14:42Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
