dc.description	Mutant of dwarf rice (Oryza sativa L.) were treated with three different concentrations of gibberellicacid originated from two sources (Gibberellin and Pro-Gibb) and submitted to the determinationof bigger height, in relation to the soil leveI. Mensurations were realized in each seven days atgreenhouse conditions under mean temperature of 25°C. lt was concluded that concentrations of 10mg L-1 of gibberellin originated from Pro-Gibb or Gibberellin was enough to promote a differentiatedperformance of the test plant. For the study of leaf anatomy Pro-Gibb presented, under all testedconcentration, increase of mesophyll thickness in relation to Gibberellin. In this analysis, source andinteraction between source and concentration applied promoted significant variations betweenthe mean data.	en-US
dc.description	Plantas mutantes de arroz anão (Oryza sativa L.) foram tratadas com três diferentes concentraçõesde ácido giberélico originários de duas fontes (Gibberellin e Pro-Gibb) e submetidas à determinaçãoda maior altura, em relação ao nível do solo. As mensurações foram realizadas a cada 7 dias emcasa de vegetação à temperatura ambiente média de 25°C. Concluiu-se que a concentraçãode 10 mg L-1 de giberelina proveniente de Pro-Gibb ou Gibberellin mostrou-se suficiente paracausar o desempenho diferenciado da planta-teste; porém, para o estudo da anatomia foliar, Pro-Gibb apresentou, para todas as concentrações testadas, aumento na espessura do mesofilo emrelação a Gibberellin. Nesta análise, fonte e interação entre a fonte e a concentração aplicadapromoveram variações significativas entre as médias.
