Resumo: | A trial was conducted to test the effects of GA3, 2,4-D, metiquat chloride and 2-chloroetylfosfonic acid on the opening of pineapple flowers and upon some qualitative and quantitative characteristics of the fruit. Only the 2-chloroetylfosfonic acid (1.000, 2.000 and 3.000 ppm) inhibited flower opening. This compound also reduced the juice content and the number of slips per plant significantly. Despite some significant differences among a few treatments, in general most treatments, independent of their concentrations, had little effects on the other parameters studied, such as crown size, % eatable portion of the fruit, fruit weight and length fruit core diameter, total soluble solids, acidity and pH. Preliminary observations still showed that Fusarium moniliforme attack was lower in the fruits treated with 2-chloroetylfosfonic acid. The establishment of a cultural practice which inhibits the opening of the pineapple flowers could be valuable for the control of such disease. Further studies should be carried out in order to corroborate the preliminary results obtained in the present work. |

Neste trabalho foram estudados os efeitos do cloreto de metiquat, 2,4-D, AG3 e do ácido 2-cloroetilfosfônico, em três concentrações cada, na abertura das flores do abacaxizeiro. O ácido 2-cloroetilfosfônico foi o único produto a inibir totalmente a abertura das flores, nas dosagens de 1.000, 2.000 e 3.000 ppm, reduzindo também, significativamente, o número de mudas por planta e a percentagem de suco. Apesar de em alguns poucos casos ocorrerem diferenças estatísticas, em geral, não houve influência dos tratamentos sobre os aspectos qualitativos dos frutos, bem como sobre os valores referentes ao comprimento da coroa, percentagem de parte comestível do fruto, peso médio dos frutos, diâmetro do fruto e do eixo do fruto, comprimento do fruto sem coroa. Observações preliminares mostraram ainda que a incidência de fusariose nos frutos foi menor nos tratamentos com o ácido 2-cloroetilfosronico. O estabelecimento de uma prática cultural capaz de inibir a abertura das flores do abacaxizeiro poderia constituir-se num auxiliar valioso no controle da fusariose, tornando-se necessária, portanto, a realização de estudos mais detalhados, a fim de se comprovarem os resultados obtidos no presente trabalho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCunha, Getúlio Augusto Pinto da2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16603Pesquisa Agropecuaria Brasileira; v.15, n.4, abr. 1980; 423-429Pesquisa Agropecuária Brasileira; v.15, n.4, abr. 1980; 423-4291678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16603/10892info:eu-repo/semantics/openAccess2014-04-15T19:35:38Zoai:ojs.seer.sct.embrapa.br:article/16603Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:35:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
