Resumo: The objective of this work was to evaluate the effects of plant growth regulators on the effective fruit set and quality of atemoya 'Gefner' parthenocarpic fruit. The experiment was carried out in an orchard of atemoya 'Gefner' in Homestead, Florida, USA. A randomized complete block design was carried out with four treatments, five replicates, and six flowers per plot. Treatments were composed of: T1, 450 mg L‑1 naphthaleneacetic acid and 1,000 mg L‑1 gibberelic acid; T2, 100 mg L‑1 promalin and 1,000 mg L‑1 gibberelic acid; T3, 1,000 mg L‑1 gibberelic acid; and T4, artificial pollination (control). Effective fruit set, and fruit growth and quality were evaluated. The application of naphthaleneacetic and gibberelic acids on flowers of atemoya 'Gefner' provided high fruit set, similar to that of artificial pollination. Gibberelic acid application, associated or not with naphthaleneacetic acid or promalin, results in later and smaller atemoya 'Gefner' fruit than those obtained by artificial pollination, but with good proportion of pulp, excellent soluble solids content and, mainly seedless fruit (parthenocarpic fruit).

O experimento foi realizado em pomar de atemoia 'Gefner', em Homestead, Flórida, EUA. Utilizou-se um delineamento experimental de blocos ao acaso, com quatro tratamentos, cinco repetições e seis flores por parcela. Os tratamentos foram compostos por: T1, ácido naftaleno acético a 450 mg L‑1 e ácido giberélico a 1.000 mg L‑1; T2, promalina a 100 mg L‑1 e ácido giberélico a 1.000 mg L‑1; T3, ácido giberélico a 1.000 mg L‑1; e T4, polinização artificial (testemunha). Foram avaliados a frutificação efetiva, o crescimento e a qualidade dos frutos. A aplicação dos ácidos naftaleno acético e giberélico a flores de atemoia 'Gefner' proporcionou elevada frutificação efetiva, semelhante à da polinização artificial. A aplicação do ácido giberélico, associado ou não ao ácido naftaleno ou à promalina, resulta na produção de frutos de atemoia 'Gefner' mais tardios e menores do que os oriundos da polinização artificial, mas com boa proporção de polpa, excelente teor de sólidos solúveis e, principalmente, frutos sem sementes (partenocárpicos).Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCAPES e FAPEMIGPereira, Marlon Cristian ToledoCrane, Jonathan HenryNietsche, SilviaMontas, WandaSantos, Márcio Adriano2014-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/18684Pesquisa Agropecuaria Brasileira; v.49, n.4, abr. 2014; 281-289Pesquisa Agropecuária Brasileira; v.49, n.4, abr. 2014; 281-2891678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/18684/12634https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/18684/11082info:eu-repo/semantics/openAccess2014-06-11T18:46:47Zoai:ojs.seer.sct.embrapa.br:article/18684Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-11T18:46:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
