Resumo: Growth regulators were applied to tomato plants and their effects on mineral nutrition, osmotic potential, and incidence of blossom-end rot (BER) were studied. Gibberellic (GA) promoted high incidence of BER in tomato fruits when e high level of ammonium sulphate was used. Under the same conditions, treatment with succinic acid-2, 2-dimethylhydrazide (SADH), indole-3-acetic acid (IAA), or (2-chloroethyl) trimethylammonium chloride (CCC) caused lower incidence of BER. Higher levels of nitrogen, calcium, and magnesium occured in the stems of plants sprayed with CCC. Treatments with 6-furfuryiamino purine (FAP), SADH and (2-chloroethyl) phosphonic acid (CEPA) presented and increase in nitrogen level in the stem, CEPA also increased calcium content in stems. These growth regulators did not alter the levels of macronutrients in leaves of tomatoes in relation to control. Plants treeted with GA and SADH had a lower (more negative) loaf osmotic potential under water deficit in the soil.

Plantas tratadas com GA 100 ppm apresentaram alta incidência da anomalia fisiológica, sendo que as aplicações da SADH 4000 ppm, CCC 2000 ppm e IAA 100 ppm reduziram a ocorrência de podridão estilar dos fruto. Plantas com frutos apresentando a anomalia mostraram teores mais baixos de cálcio nos frutos e folhas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCastro, Paulo R.C.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16772Pesquisa Agropecuaria Brasileira; v.13, n.2, fev. 1978; 61-67Pesquisa Agropecuária Brasileira; v.13, n.2, fev. 1978; 61-671678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16772/11096info:eu-repo/semantics/openAccess2014-04-15T19:14:29Zoai:ojs.seer.sct.embrapa.br:article/16772Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:14:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
