Resumo: | This trial set out to study the effectiveness of preimmunization for the control of PRSV-W in winter bush squash (cv. Caserta) in São Manuel, SP. Four replications with ten plants each were set out in a randomized completed block design in order to evaluate five treatments: 1) Control submitted to natural infection; 2) Preimmunization with a mild strain; 3) and 4) Preimmunization followed by inoculation with a potent strain five and ten days after, respectively; 5) Inoculation with a potent strain. The potent strain reduced drastically the fruit yield, and all harvested fruits showed mosaic symptoms. Preimmunization, alone of followed by inoculation with a potent strain ten days after, increased the marketable immature fruit yield in relation to the control and plants inoculated with a potent strain, but when a challeng incoculation with the potent strain was carried out only five days after preimmunization, there was a reduction in the immature fruit yield. Most preimmunizated plants that showed mosaic symptoms were infected by ZYMV, detected by ELISA test. It was concluded that preimmunization was efficient, increasing fruit yield and quality, even when the plants were inoculated with a potent strain ten days after the inoculation of the mild strain. |

Caserta) contra a infecção por estirpes fortes foi instalado um experimento no município de São Manuel, SP. O delineamento foi de blocos ao acaso, com quatro repetições e dez plantas por parcela, onde foram avaliados cinco tratamentos: 1) Testemunha submetida a infecção natural; 2) Premunização com um isolado fraco; 3) e 4) Premunização com o isolado fraco seguido de desafio com um isolado forte 5 e 10 dias após, respectivamente; 5) Inoculação com o isolado forte. Plantas inoculadas com o isolado forte apresentaram redução drástica na produção de frutos imaturos, sendo que todos os frutos colhidos apresentaram sintomas de mosaico. O desafio 5 dias após a premunização também reduziu a produção, enquanto que a premunização, isolada ou seguida de desafio 10 dias após, aumentou a produção de frutos imaturos comercializáveis em relação às plantas infectadas com o isolado forte e com infecção natural (testemunha). Em quase todas as plantas premunizadas que apresentaram sintomas de mosaico detectou-se infecção com ZYMV pelo teste ELISA. Concluiu-se que a premunização foi eficiente em aumentar a produção e qualidade dos frutos, protegendo as plantas mesmo quando incoculadas com o isolado forte 10 dias após a inoculação do isolado fraco.Universidade Federal de Santa Catarina2001-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21695Biotemas; v. 14 n. 2 (2001); 23-362175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21695/19661Copyright (c) 2001 Antonio Ismael Inácio Cardoso, Marcelo Agenor Pavanhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCardoso, Antonio Ismael InácioPavan, Marcelo Agenor2022-11-18T13:45:21Zoai:periodicos.ufsc.br:article/21695Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-18T13:45:21Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
