Resumo: | Pruning and thinning are practices that can change the source:sink relations and thus influence the quality and fruit storage capacity. This study evaluated the influence of the pruning of the main stem and the fruit thinning in quality and postharvest conservation of melon. For this, two experiments were conducted, with Galia melon (hybrid Amaregal) and Charentais melon (hybrid Banzai), both with two phases, field and laboratory. In the field, the plants were submitted to the pruning of the main stem and the fruit thinning; the fruits were harvested at 66 and 74 days after sowing (DAS), respectively for Galia and Charentais melon. In the laboratory, the fruits were cleaned, characterized and stored in the freezer. The experiment was conducted in split-plot, and the portion composed of the factorial 2 x 4 + 1: pruning (pruning and unpruning), thinning times (32, 35, 38 and 41 DAS to Galia melon; and 42, 45, 48 and 51 DAS for the Charentais melon) and an additional control (unpruning and unthinning); and the sub-plot was constituted by the storage times (0, 7, 14, 21 and 28 days), with four blocks. The following analyzes were performed: number of fruits per plant (NFP), fruit weight (FW), productivity (PROD), weight loss (WL), external (EA) and internal appearance (IA), epicarp and mesocarp color, flesh firmness (FF), titratable acidity (TA), soluble solids (SS) , total soluble sugars (TSS), reducing sugars (RS) and non-reducing sugar (NRS), and vitamin C (VITC). In the Galia melon, pruning improved the epicarp color and increased the NRS, but reduced the SS. Thinning to 41 DAS depreciated the EA and reduced SS, TSS and NRS, but was positive for epicarp and mesocarp color, and increased VITC. Pruning reduced the TA and the loss in FF at 14 and 28 days of storage, respectively. Pruning associated with thinning to 38 DAS reduced the WL after 28 days of storage and result in an increased RS. In storage was observed decreasing in EA, IA, SS, RS, NRS, TSS and VITC. In the Charentais melon, the pruning reduced WL to 28 days of storage. Pruning also decreased TA. The treatments with pruning and thinning positively influenced the fruit epicarp color. Thinning to 42 DAS increased the SS and SS/TA ratio. In storage period there was a reduction in EA, IA, FF, TA, RS, VITC and increase in SS, SS/TA ratio, TSS and NRS |

Assim, este estudo objetivou avaliar a influência da poda da haste principal e do raleio dos frutos na qualidade e conservação pós-colheita de melão. Para isto, foram realizados dois experimentos, sendo um com o melão Gália ‘Amaregal’ e o outro com melão Charentais ‘Banzai’, ambos com uma fase de campo e outra de laboratório. Em campo, as plantas foram submetidas à poda da haste principal e ao raleio dos frutos, com a colheita ocorrendo aos 66 e 74 dias após a semeadura (DAS), respectivamente para o melão Gália e Charentais. Os frutos foram levados para o laboratório, onde foram higienizados, caracterizados e armazenados em câmara fria. Os experimentos foram conduzidos em esquema de parcelas sub-divididas, sendo a parcela constituída pelo fatorial 2 x 4 +1: poda (sem poda e com poda), épocas de raleio (32, 35, 38 e 41 DAS para o melão Gália; e 42, 45, 48 e 51 DAS para o melão Charentais) e uma testemunha adicional (sem poda e sem raleio); e a sub-parcela constituída pelo armazenamento (0, 7, 14, 21 e 28 dias), com quatro blocos. As seguintes análises foram realizadas: número de frutos por planta (NFP), massa média dos frutos (MMF), produtividade (PROD), perda de massa (PM), aparência externa (AE) e interna (AI), cor do epicarpo e mesocarpo, firmeza de polpa (FP), acidez titulável (AT), teor de sólidos solúveis (SS), açúcares solúveis totais (AST), açúcares redutores (AR) e não-redutores (ANR), e vitamina C (VITC). Verificou-se no melão Gália que a poda da haste principal do meloeiro realçou a cor do epicarpo e aumentou o ANR, porém reduziu os SS. O raleio aos 41 DAS depreciou a AE e reduziu os SS, AST e ANR, mas foi positivo para a cor do epicarpo e mesocarpo, bem como aumentou a VITC. A poda reduziu a AT e a perda na FP dos frutos aos 14 e 28 dias de armazenamento, respectivamente. A poda associada ao raleio aos 38 DAS reduziu a PM aos 28 dias de armazenamento e propiciou incremento no AR dos frutos. E ao longo do armazenamento houve redução nas notas de AE e AI e nos teores de SS, AR, ANR, AST e VITC. Por outro lado, no melão Charentais, a poda reduziu a PM dos frutos aos 28 dias de armazenamento. A poda também diminuiu a AT dos frutos. Os tratamentos de poda e raleio influenciaram positivamente a cor do epicarpo dos frutos. O raleio aos 42 DAS elevou os SS e a relação SS/AT. Durante o período de armazenamento houve redução na AE, AI, FP, AT, AR e VITC, e incremento nos SS, relação SS/AT, AST e ANRCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Federal Rural do Semi-ÁridoBrasilUFERSAPrograma de Pós-Graduação em FitotecniaMedeiros, José Francismar de27348636420http://lattes.cnpq.br/9567732690904131Aroucha, Edna Maria Mendes51611554349http://lattes.cnpq.br/308050626073227101381690475http://lattes.cnpq.br/5037173259464950Nascimento, Iarajane Bezerra do87794098491http://lattes.cnpq.br/1278800766326194Chaves, Sérgio Weine Paulino01958614424http://lattes.cnpq.br/0335679068121878Dantas, Mara Suyane Marques01087201446http://lattes.cnpq.br/9205576230995806Ferreira, Rafaella Martins de Araújo2017-03-21T14:50:59Z2016-02-29info:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfFERREIRA, Rafaella Martins de Araújo.
