[en] The experiment was realized to verify the possibility of applying Boron as foliar fertilization with growth regulators: indol acetic acid, giberellic acid, ethephon and cycocel. The other objective was to compare the foliar and soil fertilization, with Boron, on the lettuce culture. The results showed that there wasn't difference of production between the treatments. Meanwhile the application of growth regulator modified the Boron grade in the leaves. (author)

O ensaio foi instalado para se verificar a possibilidade de se aplicar Boro via foliar, associado a fitohormonios: acido indol acetico, acido giberelico, ethephon e cycocel bem como, comparar os efeitos da adubacao foliar com Boro em comparacao com a realizada no solo, na cultura da alface. Os resultados obtidos mostraram que nao houve diferencas de producao entre os diversos tratamentos. Estretanto, a aplicacao de fitohormonios modificou os teores de Boro nas partes aereas da alface.
