Resumo: | Abstract – The fruit thinning of an apple tree is one of the most important cultural practices for increasing fruit size and quality, in addition to avoiding the alternation of production. Chemical thinning is widely used in apple growing, because it reduces the need for labor and allows the activity to be performed in an appropriate period. Combinations of flowering and post-flowering chemical thinners have provided more effectve results for cultivars with high fruit set. The aim of this work was to evaluate the response of the application of combinations of flowering and post-flowering chemical thinners in ‘Fuji Suprema’ apple tree. The experiments were conducted from 2011 to 2013 evaluating the combination of benzyladenine (BA) with GA4+7+BA, ANA and ethephon, used in different concentrations and times of application. The flowering and post-flowering chemical thinners are efficient for ‘Fuji Suprema’ apple tree. The flowering chemical thinners GA4+7+BA or BA and the post-flowering chemical thinner BA combined with ANA or ethephon presented the closest results to hand thinning, being an efficient alternative. |

O raleio químico é amplamente utilizado na cultura da macieira, pois reduz a necessidade de mão de obra e permite que a atividade seja executada em um período adequado. Combinações deraleantes de floração e pós-floração têm proporcionado resultados mais efetivos para cultivares com alta frutifcação efetiva. O objetivo do trabalho foi avaliar a resposta à aplicação de combinações de raleantes de floração e pós-floração na macieira ‘Fuji Suprema’. Os experimentos foram conduzidos de 2011 a 2013 avaliando a combinação de benziladenina (BA) com GA4+7+BA, ácido nafaleno acétco (ANA) e etefon, utilizados em diferentes concentrações e épocas de aplicação. Os raleantes de floração e pós-floração são eficientes para macieira ‘Fuji Suprema’. Os raleantes de floração GA4+7+BA e BA e as combinações de BA com ANA ou BA com etefon em pós-floração apresentam os resultados mais próximos do raleio manual, sendo recomendados para raleio de frutos na cultura da macieira.
