Resumo: The experiment was undertaken in Fraiburgo in 1973 using five - year - old plants and repeated for four consecutive years on apple cv. Golden Delicious/MI-793. Different combinations of mineral oil and DNOC concentrations were applied in an only annual spray at bud-swell stage. The studied parameters were flowering and bloom periods, percentage of lateral and terminal bud-break, number of flower cluster, "fruit set", total number of fruits before and after thinning, fruit production and average weight. The treatments with mineral oil + dinitro-orthocresol (DNOC) advanced leaf and flower bud-break. The same treatments increased the percentage of lateral and terminal bud-break, number of flower cluster and production as a result of an increase of concentration of mineral oil and DNOC until 0,2%. Increased bud-break caused higher number of spurs and enhanced production for the subsequent years. Mineral oil and DNOC negatively influenced the fruit set and average fruit weight was not affected.

Diversas combinações de concentrações de óleo mineral e DNOC foram aplicadas em uma única pulverização anual, no inchamento das gemas. As seguintes variáveis foram analisadas: época de brotação e floração, percentagem de gemas laterais e terminais brotadas, número de cachos florais, "fruit set", número total de frutos e após raleio, produção e peso médio do fruto. A brotação e floração foram antecipadas nos tratamentos com óleo mineral + dinitro-ortocresol (DNOC). Houve aumento na brotação das gemas laterais, no número de cachos florais e na produção com elevação da concentração de óleo mineral DNOC até 0,2%. O acréscimo na brotação provocou maior formação de esporões, aumentando a produção nos anos subsequentes. O "fruit set" foi influenciado negativamente e não houve efeito das aplicações de óleo mineral e DNOC sobre o peso médio do fruto.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPasqual, MoacirPetri, José Luiz2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16631Pesquisa Agropecuaria Brasileira; v.14, n.1, jan. 1979; 11-18Pesquisa Agropecuária Brasileira; v.14, n.1, jan. 1979; 11-181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16631/10934info:eu-repo/semantics/openAccess2014-04-15T19:21:29Zoai:ojs.seer.sct.embrapa.br:article/16631Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:21:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
