Resumo: | The objective of this study was to evaluate the effect of the extract from a native plant from caatinga (Allamanda blanchetti) in the control of the fungus Alternaria brassicicola, concerning to induction of resistance mechanisms in seedlings of kale and direct fungitoxic action. Under greenhouse conditions, the seedlings of kale were sprayed with extracts from A. blanchetti extracted at hot and at cold at concentrations of 0; 100; 500 to 1000 ppm. Analysis of disease severity were performed at 5; 6; 7; 8; 9:10 days after inoculation. Peroxidases were analyzed five times 0; 24; 72; 120, and 168 hours after spraying the seedlings with the extracts. Furthermore, the capacity of the hot and cold extracts was also evaluated at 0; 100; 500, and 1000 ppm to inhibit the germination of spores of A. brassicicola. The concentrations of 1000 ppm of the hot and cold extracts were more effective in controlling the disease. The extract of A. blanchetti induced an increase in the peroxidase activity at 24 hours after treatment application and promote inhibition of germination of spores of A. brassicicola. These results indicate the potential from A. blanchetti to control A. brassicicola, both by direct action and the activation of defense mechanisms. |

Em condições de casa de vegetação, as mudas de couve-manteiga foram pulverizadas com os extratos de A. blanchetti extraídos a quente e a frio, nas concentrações 0, 100, 500 e 1000 ppm. Avaliações da severidade da doença foram realizadas a 5, 6, 7, 8, 9 e 10 dias após a inoculação. Peroxidases foram analisadas em cinco tempos, quais sejam, 0, 24, 72, 120 e 168 horas após a pulverização das mudas com os extratos. Além disso, fora avaliado também a capacidade dos extratos a quente e a frio a 0, 100, 500 e 1000 ppm em inibir a germinação dos esporos de A. brassicicola. As concentrações de 1000 ppm dos extratos a quente e a frio foram as mais eficientes no controle da doença. O extrato de A. blanchetti induziu aumento da atividade de peroxidase às 24 horas após a aplicação dos tratamentos e promoveu inibição da germinação dos esporos de A. brassicicola. Estes resultados indicam o potencial de A. blanchetti no controle de A. brassicicola, tanto pela ação direta quanto pela ativação de mecanismos de defesa.Universidade Federal Rural do Semi-Árido2015-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/373310.1590/1983-21252015v28n304rcREVISTA CAATINGA; Vol. 28 No. 3 (2015); 36-46Revista Caatinga; v. 28 n. 3 (2015); 36-461983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAporhttps://periodicos.ufersa.edu.br/caatinga/article/view/3733/pdf_273Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessBarros, Juliana de Souza GranjaGomes, Erbs Cintra de SouzaCavalcanti, Leonardo Sousa2023-07-27T12:50:37Zoai:ojs.periodicos.ufersa.edu.br:article/3733Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:08.613388Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
