Resumo: The productive potential of plants may be affected by nutritional disorders induced by saline stress. The objective was to study the influence of different salinity levels on mineral nutrition of peach palm (Bactris gasipaes H.B.K.) seedlings in greenhouse conditions with nutritive solution. The experimental design was in randomized blocks, with seven treatments and four replications. The treatments consisted of the following dosages (mmol L-1): 0.0 of Na and 0.5 of Cl; 1.0 of Na and 0.5 of Cl (control); and 5.0, 15.0, 30.0, 60.0 and 120.0 of NaCl. The content of the macronutrients varied with the salinity, there was reduction of P and K in the roots, K and Ca in the leaves, and S in different parts of the plants. Therefore, there was increase of Na and Cl in different parts of the plant. The enhancement of the ratios Na/K, Na/Ca, Na/Mg, Cl/N, Cl/P and Cl/S induced a nutritional imbalance in the plant.

O objetivo deste trabalho foi estudar a influência de diferentes níveis de salinidade na nutrição mineral de mudas de pupunheira (Bactris gasipaes H.B.K.), mediante o uso de solução nutritiva, em casa de vegetação. O experimento foi instalado em blocos ao acaso, com sete tratamentos e quatro repetições. Os tratamentos constaram das seguintes doses (mmol L-1): 0,0 de Na e 0,5 de Cl; 1,0 de Na e 0,5 de Cl (controle); e 5,0, 15,0, 30,0, 60,0 e 120,0 de NaCl. Os teores dos macronutrientes variaram em razão da salinidade, e verificou-se que o P e K apresentaram seus teores reduzidos nas raízes, o K e o Ca, nas folhas e o S, nas diferentes partes, enquanto o Na e o Cl apresentaram teores incrementados nas diferentes partes da planta. As relações Na/K, Na/Ca, Na/Mg, Cl/N, Cl/P e Cl/S aumentaram, causando um desbalanço nutricional na planta.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFernandes, Antonio Rodriguesde Carvalho, Janice GuedesCuri, NiltonPinto, José Eduardo Brasil PereiraGuimarães, Paulo de Tácito Gontijo2002-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6509Pesquisa Agropecuaria Brasileira; v.37, n.11, nov. 2002; 1613-1619Pesquisa Agropecuária Brasileira; v.37, n.11, nov. 2002; 1613-16191678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6509/3566info:eu-repo/semantics/openAccess2014-07-21T18:51:35Zoai:ojs.seer.sct.embrapa.br:article/6509Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-21T18:51:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
