Resumo: | This study was carried out to investigate the effects of different AVG (aminoethoxyvinylglycine) treatments on pre-harvest fruit drop rates and ripening levels of ‘Jonagold’ apples. A total of 225 mg L-1 AVG dose was applied at once in a single application at different times or divided into doses and applied different times. Compared to control treatment, entire AVG treatments increased fruit removal force and significantly decreased the pre-harvest drop rates. AVG treatments applied at once (225 mg L-1) 8 or 4 weeks before the anticipated harvest time were found to be more effective than the divided treatments. AVG treatments inhibited ethylene biosynthesis and such an inhibition was more distinctive in single 225 mg L-1 treatments. AVG treatments decreased flesh softening, starch degradation rates and consequently retarded fruit ripening. The 225 mg L-1 AVG treatment applied 4 weeks before the harvest significantly increased L* value and hue angle both in the year 2010 and 2011. NAA (naphtaleneacetic acid) at 10 mg L-1 sprayed 4 and 2 weeks before anticipated harvest was found to be insignificant in control of pre-harvest fruit drops. NAA treatment decreased flesh firmness, and did not have any significant effects on ethylene biosynthesis. |

Foi aplicada uma dose AVG total de 225 mg L-1 numa só vez numa única aplicação em momentos diferentes ou dividida em doses aplicadas e tempos diferentes. Em comparação ao tratamento controle, as aplicações de AVG aumentaram a força de remoção dos frutos e reduziram significativamente as taxas de queda na pré-colheita. A aplicação de AVG de uma só vez (225 mg L-1) ou 4 a 8 semanas antes da época da colheita mostrou-se mais eficaz do que as aplicações efetuadas em doses. O tratamento com AVG inibe a biossíntese de etileno, sendo que esta inibição se verificou mais significativa em tratamentos individuais de 225 mg L-1. O tratamento com AVG diminuiu o amolecimento da polpa, as taxas de degradação do amido e consequentemente retardou o amadurecimento dos frutos. O tratamento com doses de 225 mg L-1 de AVG aplicadas quatro semanas antes da colheita aumentou significativamente o valor L * e o ângulo de cor, tanto no ano de 2010 como de 2011. A pulverização de NAA (ácido naftaleno acético) a 10 mg L-1 2 a 4 semanas antes da colheita foi considerada insignificante no controle da queda de frutos na pré-colheita. O tratamento com NAA diminuiu a firmeza da polpa, e não tem quaisquer efeitos significativos sobre a síntese de etileno.UEL2015-12-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1849310.5433/1679-0359.2015v36n6p3595Semina: Ciências Agrárias; Vol. 36 No. 6 (2015); 3595-3604Semina: Ciências Agrárias; v. 36 n. 6 (2015); 3595-36041679-03591676-546Xreponame:Semina.
