Resumo: | Strawberries (Fragaria x ananassa Duch.) cv. Campinas were cultivated in nutrient solution using five levels of molybdenum (Mo), 0.0010 ppm, 0.010 ppm, 0.10 ppm, 1.0 ppm and control (without applying molybdenum). The experiment was carried out in greenhouse and phytothron at Agronomy School of the Federal University of Rio Grande do Sul, Brazil, to evaluate the changes in the mineral status of the leaves and the quality of the berries. The concentration of Mo in the leaves, at the beginning of fruiting stage, varied from 0.5 ppm to 64 ppm. No visual symptoms of deficiency or toxicity were observed. The total N in the levels was affected significantly by Mo and this can probably be attributed to its toxic effect. However nitrate, P, K, Ca, Mg and leaf area were not affected by the treatments. Total solid solubles, acidity, total solid solubles/acidity and ascorbic acid contents of the berries were not influenced by Mo. Average weight of the berries were affected by treatments and presented a quadratic regression response. |

Campinas (IAC 2712) foram cultivados em solução nutritiva e submetidos a cinco níveis de molibdênio (Mo): 1,0 ppm, 0,10 ppm, 0,010 ppm, 0,0010 ppm e testemunha (sem aplicação de Mo). A fase experimental foi conduzida em casa de vegetação e câmara de crescimento, na Faculdade de Agronomia da UFRS para avaliar as alterações no estado nutricional das plantas e na qualidade de seus frutos. A concentração de Mo nas folhas, colhidas de plantas no estádio de início de frutificação, aumentou linearmente, de 0,5 ppm a 64 ppm. Não se verificaram sintomas de deficiência ou toxidez. Os teores foliares de nitrato, P, K; Ca e Mg e a área foliar não foram afetados pelos níveis de Mo; no entanto, os teores de N-total diminuíram linearmente com o aumento da concentração de Mo, o que se atribui a um possível efeito de sua fitotoxidez. Os sólidos solúveis totais (SST), a acidez titulável, a relação SST/acidez e os teores de ácido ascórbico dos morangos não foram afetados pelo Mo. O peso médio de frutos sofreu um efeito quadrático, aumentando até a concentração de 0,10 ppm de Mo na solução.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBender, Renar JoãoBarros, Ingrid B.I. de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15323Pesquisa Agropecuaria Brasileira; v.19, n.1, jan. 1984; 73-78Pesquisa Agropecuária Brasileira; v.19, n.1, jan. 1984; 73-781678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15323/9170info:eu-repo/semantics/openAccess2014-04-16T19:09:18Zoai:ojs.seer.sct.embrapa.br:article/15323Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:09:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
