Resumo: | The effects of six concentrations of naphthalene acetic acid (N.A.A.) applied in pineapple fruits were studied. A randomized block design was used, with seven treatments or concentrations (0, 50, 75, 100, 125, 150 and 175 of A.N.A. ppm). Each treatment was replicated three times. No statistical difference was found for weight, diameter and size of fruit and medulla diameter. Rates of 125 and 175 ppm of N.A.A. increased significantly the crown length. There was a significant increase in total fruit acidity with the application of 175 ppm rate of N.A.A. On the other hand, rates of 125 and 175 ppm of N.A.A. resulted in a reduction of soluble solids content. Significant differences among treatments did not occur, but the different rates of N.A.A. studied showed a trend toward increasing wieght and size of pineapple fruits. |

O delineamento experimental foi o de blocos ao acaso com sete tratamentos ou concentrações de A.N.A. (0, 50, 75, 100, 125, 150 e 175 ppm) e três repetições. Não se constatou diferença estatística quanto ao peso, diâmetro e tamanho dos frutos ou diâmetro da medula. Nas concentrações de 125 e 175 ppm, o comprimento da coroa aumentou, e com 175 ppm a acidez da polpa diminuiu. Por outro lado, 125 e 175 ppm de A.N.A., diminuíram o teor de sólidos solúveis dos frutos. Apesar de não ter ocorrido diferença significativa entre os tratamentos quanto ao peso e às dimensões do fruto, a aplicação de A.N.A. mostrou uma tendência em aumentá-las.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraVieira, AlcílioGadêlha, Ricardo Sérgio de Sarmento2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16410Pesquisa Agropecuaria Brasileira; v.17, n.12, dez. 1982; 1721-1724Pesquisa Agropecuária Brasileira; v.17, n.12, dez. 1982; 1721-17241678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16410/10657info:eu-repo/semantics/openAccess2014-04-16T11:50:18Zoai:ojs.seer.sct.embrapa.br:article/16410Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T11:50:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
