Resumo: The objective of this work was to evaluate the influence of peroxidase and polyphenol oxidase enzymes in anthracnose resistance of four bean cultivars. Seedlings were sprinkled with salicylic acid and delta race of Colletotrichum lindemuthianum (inducer fungus) and after three days they were inoculated with 33/95 virulent pathotype of C. lindemuthianum. Enzyme activity and phenol levels were evaluated three days afte rinducer fungus application and five days after inoculation with virulent pathotype. Plants treated with salicylic acid and inducer fungus presented higher activity increases of both enzymes, in all cultivars. Higher impulses in enzymatic activity were observed in cultivars with higher disease resistance. One isoperoxidase appeared in treatments with inducer fungus, salicylic acid, after inoculation with virulent pathotype, and in control plants, in AB 136, Rio Tibagi and Macanudo cultivars. Positive correlation was observed among peroxidase and polyphenol oxidase activity, phenolic compound levels and anthracnose resistance.

Plântulas de feijão foram pulverizadas com ácido salicílico e com a raça delta de Colletotrichum lindemuthianum (fungo indutor) e submetidas à inoculação do patótipo virulento 33/95 de C. lindemuthianum três dias após a aplicação do fungo indutor e do ácido salicílico. Essas plantas foram avaliadas quanto à atividade enzimática e teores de fenóis, três dias após a aplicação do fungo indutor e cinco dias após a inoculação do patótipo virulento. Acréscimos nas atividades dessas enzimas foram maiores nos tratamentos com ácido salicílico e fungo indutor em todas as cultivares. Maiores estímulos nas atividades enzimáticas foram observados nas cultivares com maior resistência à doença. Constatou-se o aparecimento de uma isoperoxidase nos tratamentos com fungo indutor, ácido salicílico, após inoculação do patótipo virulento, e na testemunha, nas cultivares AB 136, Rio Tibagi e Macanudo. Houve correlação positiva entre as atividades da peroxidase e da polifenoloxidase, os teores de compostos fenólicos e a resistência à antracnose.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCampos, Ângela DinizFerreira, Alfredo GuiHampe, Magdolna Maria VozaríAntunes, Irajá FerreiraBrancão, Nelyda Silveira, Expedito PauloOsório, Vera AllgayerAugustin, Eliane2004-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6820Pesquisa Agropecuaria Brasileira; v.39, n.7, jul. 2004; 637-643Pesquisa Agropecuária Brasileira; v.39, n.7, jul. 2004; 637-6431678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6820/3876info:eu-repo/semantics/openAccess2014-07-23T18:55:41Zoai:ojs.seer.sct.embrapa.br:article/6820Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-23T18:55:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
