“…However, in a study with Orange Flesh and Hy Mark melons, pruned plants produced fruits with higher average mass than the unpruned plants (Pereira et al 2003). For Cantaloupe melon, plants with higher number of leaves (source) produced fruits with higher diameter (Queiroga et al 2008a;Bhering et al, 2013).…”

RESUMO Influence of the main stem pruning and fruit thinning on quality of melon 1Among many management practices used in melon crops, those that change source: sink relationship, such as pruning and fruit thinning, directly influence production, affect fruit size and its composition, including sugar and vitamin contents. The objective of this study was to evaluate the influence of pruning of the main stem and time of fruit thinning in melon postharvest quality. Thus, two experiments were set up in Mossoró, state of Rio Grande do Norte, each with a melon hybrid (Amaregal and Banzai). Each experiment was conducted in a randomized block, in a (2 x 4) + 1 factorial design, 2 pruning management (with and without pruning), 4 levels of fruit thinning (3, 6, 9 and 12 DARB -days after removal agro textile blanket) and a control (without pruning and thinning), and four replications. Fruits were harvested at commercial maturity and transported to the Laboratory of Food Technology of UFERSA, where they were evaluated for the following characteristics: weight, diameter, length, flesh thickness, flesh firmness, soluble solids, pH, and titratable acidity, soluble solids: titratable acidity ratio and vitamin C. No interaction between factors in any of the experiments was found. Titratable acidity (0.077%) and vitamin C content (3.4 mg/100 g) in Amaregal melon and soluble solids (10.2%) in Banzai melon were lower in the treatments with stem pruning. In Amaregal melon, fruits showed longer length (134 mm) and greater flesh firmness (40 N) when thinning was carried out on 6 DARB, and as thinning was delayed, it found a decrease in the values of soluble solids, SS: TA ratio and pH. In Banzai melon, fruits showed greater flesh thickness (33.5 mm) and SS: TA (247.5) ratio when thinning was carried out on 6 DARB. However, delay in thinning promoted an increase in pH and vitamin C content of the fruits. Pruning of the main stem and thinning season had effect on the quality of Amaregal and Banzai melons in different ways.Dentre as diversas práticas culturais utilizadas no meloeiro, aquelas que alteram a relação fonte: dreno, como poda de hastes e raleio de frutos, influenciam diretamente na produção, afetam o tamanho dos frutos e sua composição, incluindo os teores de açúcares e vitaminas. Objetivou-se, com este trabalho, avaliar a influência da poda da haste principal e da época de realização do raleio de frutos na qualidade pós-colheita de melão. Para isto, dois experimentos foram implantados no município de Mossoró-RN, cada um com um híbrido (Amaregal e Banzai). Cada experimento foi conduzido em blocos ao acaso, com esquema fatorial (2 x 4) + 1, sendo 2 níveis do fator poda (sem poda e com poda), 4 níveis do fator raleio (3, 6, 9 e 12 DARM -dias após a retirada da manta agrotêxtil) e uma testemunha (sem poda e sem raleio), e quatro blocos. Os frutos foram colhidos na maturidade comercial e transportados para o Laboratório de 790 Rafaella Martins de Araújo Ferreira et al.

Main stem pruning and fruit thinning are cultivation practices that can influence the yield and quality of the fruit. This study aimed to evaluate the effects of main stem pruning and fruit thinning on the postharvest conservation of Charentais Banzai melons. In the field, the plants were subjected to main stem pruning and fruit thinning, with harvesting done 74 days after sowing (DAS). The fruits were transported to the laboratory where they were cleaned, characterized, and stored in a cold chamber (5 °C and 90 ± 2% RH). In the field, the experiment was designed as a split-plot using a 2 × 4 + 1 factorial design, with two levels of main stem pruning (pruned and unpruned), four levels of thinning times (42, 45, 48, and 51 DAS), and a control (unpruned and unthinned). The sub-plot consisted of storage times (0, 7, 14, 21, and 28 days), with four blocks. The preharvest treatments did not significantly influence the production characteristics of the Banzai hybrid. The treatment without pruning increased the titratable acidity of fruit, and the thinning at 51 days after sowing (DAS) reduced soluble sugars. There was a decline in pulp firmness, titratable acidity, reducing sugars, and an increase in soluble solids, total soluble sugar, and non-reducing sugars during storage. Pruning the main melon stem reduced the weight loss of the fruit after 28 days of storage.
