Resumo: | The objective of this work was to evaluate the effects of acibenzolar-S-methyl and harpin protein elicitors, applied in post-harvest, in systemic resistance induction to brown-rot, on peaches. A completely randomized design was utilized, with four replicates, in a split plot scheme – injured or noninjured peaches –, and treatments were constituted of : acibenzolar-S-methyl (50 mg of a.i. L-1), two commercial products with harpin protein (80 mg of a.i. L-1); and control (distilled water). Peaches were sprayed individually with 1 mL of aqueous solution containing the treatments and, after 12 hours, the inoculation of Monilinia fructicola was carried out (0.2 mL of spore suspension with 105 spores mL-1, in each side of the fruit). Sixty hours past inoculation, the size of lesions, esporulation and percentage of control were evaluated. The contents of total protein, total phenol, total and reducing sugar, besides activity of phenylalanine ammonia-lyase (PAL), were determined. The elicitors induce resistance to M. fructicola, with reduction in fungal development. Elicitor's increased the evaluated biochemical parameters and the activity of PAL, which was related to the size reduction of lesions in peaches. The elicitors could be used in integrated management of brown-rot, in post-harvest applications. |

O delineamento experimental foi inteiramente casualizado, com quatro repetições, em parcelas subdivididas – com e sem ferimentos provocados aos frutos –, e os tratamentos foram constituídos por: acibenzolar-S-metil (50 mg do i.a. L-1), dois produtos comerciais com proteína harpina (80 mg do i.a. L-1) e uma testemunha (água destilada). Os frutos foram pulverizados, individualmente, com 1 mL de solução aquosa com os tratamentos e, após 12 horas, efetuou-se a inoculação com Monilinia fructicola (0,2 mL da suspensão com concentração de 105 esporos mL-1, em cada lado do fruto). Após 60 horas da inoculação, avaliaram-se: a área lesionada, a esporulação e o percentual de controle. Determinaram-se os teores de proteínas totais, açúcares redutores e totais, fenóis, além da atividade da enzima fenilalanina amônia-liase (FAL). Os eliciadores induziram resistência dos frutos a M. fructicola, com redução do desenvolvimento do fungo. O uso dos eliciadores aumentou os teores dos parâmetros bioquímicos avaliados e a atividade da FAL, que esteve relacionada à redução da área lesionada em pêssegos. Os indutores podem contribuir para o manejo integrado da podridão-parda em pêssegos, em pós-colheita.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDanner, Moeses AndrigoSasso, Simone Aparecida ZoletMedeiros, José Gilberto SousaMarchese, José AbramoMazaro, Sérgio Miguel2008-10-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/679Pesquisa Agropecuaria Brasileira; v.43, n.7, jul. 2008; 793-799Pesquisa Agropecuária Brasileira; v.43, n.7, jul. 2008; 793-7991678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/679/5457https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/679/473info:eu-repo/semantics/openAccess2014-07-02T17:21:06Zoai:ojs.seer.sct.embrapa.br:article/679Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-02T17:21:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
