“…It is known that tissue softening throughout the life cycle is caused by respiration and by ethylene, which markedly change fruit metabolism. The softening of apples during storage is a result of the enzymatic action on hemicelluloses and pectin (Hertog et al, 2001;Gorny et al, 2002).…”

ResumoO trabalho avaliou o efeito de estrobilurinas, boscalida, reguladores e extratos vegetais na qualidade físico-química de frutos de tomateiro (Solanum lycopersicum L.), híbrido Giuliana. Os frutos de cada tratamento foram selecionados e separados em 4 repetições: testemunha, piraclostrobina, boscalida, piraclostrobina + boscalida, IBA + GA 3 + cinetina, GA 4+7 + benzilaminopurina e extrato vegetal. A primeira aplicação foi realizada 30 dias após o transplantio e as demais, a cada 15 dias. As avaliações foram: perda de massa, acidez titulável (AT), sólidos solúveis (SS), relação SS/AT, pH, teor de ácido ascórbico, textura, açúcares solúveis totais (AST), atividade da pectinametilesterase (PME) e poligalacturonase (PG). O teor de SS, responsável pelo sabor do fruto, variou em função dos tratamentos, sendo o maior para GA 4+7 + benzilaminopurina e o menor para a testemunha. O mesmo aconteceu com a relação SS/AT. Os frutos permaneceram por 9 dias em bancada, em temperatura ambiente e ao final desse tempo, alguns tratamentos ainda apresentavam frutos ótimos para o consumo, destacandose o tratamento com boscalida, que apresentou menor perda de massa, seguido pela piraclostrobina. Assim, pode-se concluir que a aplicação dos tratamentos não alterou os valores de pH, AT e AST dos frutos. Notou-se maior atividade da PME nos tratamentos com boscalida e com a mistura de boscalida e piraclostrobina, ao mesmo tempo, se constatou menor atividade da PG nos tratamentos testemunha e piraclostrobina, indicando que alguns produtos aceleraram o processo de desmetilação das pectinas pela PME, facilitando a ação da PG. Palavras-chave: Solanum lycopersicum, estrobilurinas, boscalida, reguladores vegetais, pós-colheita AbstractThe present work evaluated the effect of strobilurins, boscalid, plant growth regulators and vegetal extracts on the physico-chemical quality of tomato fruits (Solanum lycopersicum L.), hybrid Giuliana. The fruits from each treatment were selected and separated in 4 repetitions: control, pyraclostrobin, boscalid, pyraclostrobin + boscalid, IBA + GA 3 + kinetin, GA 4+7 + benzylaminopurine and vegetal extract. The first application was carried out at 30 days after transplant and the following at every 15 days. The evaluations were: weight loss, titratable acidity (TA), soluble solids (SS), SS/TA relation, pH, ascorbic acid content, texture, total soluble sugars (TSS), activity of pectin methyl esterase (PME) and polygalacturonase (PG). The SS content, responsible for fruit flavor, varied accordingly to the treatment, being highest for GA 4+7 + benzylaminopurine and lowest for the control. The same occurred regarding the SS/AT relation. The fruits were kept on the shelf for 9 days, at room temperature, being that at the end of this period several treatments still presented fruit in optimal consumption conditions, notably the boscalid treatment, which presented lowest weight loss, followed by pyraclostrobin. Therefore, it can be concluded that the application of the treatments did not modify the values for pH, AT...

“…Modified storage atmospheres with low O 2 and high CO 2 concentrations help maintain fruit firmness due to a reduction in both cell wall hydrolytic enzyme activity and water loss, besides suppressing chilling injury symptoms [24]. The galactomannan coating used here is able to modify the internal gas composition of mangoes, with a reduction of 11% in CO 2 production and 28% in O 2 consumption [17].…”

--Introduction. Films act as semi-permeable gaseous barriers capable of maintaining fruit postharvest quality; thus coatings consisting of non-traditional sources may represent an alternative tool for producers. The objective of our work was to investigate the effect of a galactomannan coating on postharvest quality and physiology of 'Tommy Atkins' mangoes. Materials and methods. Physiologically mature mangoes were divided into four lots and stored for 16 d. Control uncoated fruits (lot 1) were stored at ambient temperature (25°C), the second lot was uncoated and refrigerated (14°C), the third lot was coated and stored at ambient temperature, and the fourth lot was coated and refrigerated. Fruit were analyzed for physicochemical quality parameters, antioxidant enzymatic activity and lipid peroxidation. Results and discussion. Control fruit (lot 1) lost almost twice the weight of uncoated refrigerated (lot 2) and coated mangoes at both temperatures (lots 3 and 4); the fruit of lot 1 softened faster. Regarding the antioxidant enzymes, the activity of superoxide dismutase decreased throughout storage without statistical differences between treatments and catalasic activity was significantly inhibited under refrigeration. At ambient temperature, coating delayed the catalasic activity peak to day 12, which was coincident with the lowest lipid peroxidation degree, evidencing the association of free radical production and scavenging mechanisms. The galactomannan coating was efficient in reducing weight loss and delaying softening; thus, it maintained quality of 'Tommy Atkins' mangoes for a longer period of time than the control treatment during storage at ambient temperature. Refrigeration (14°C) enhanced the performance of the galactomannan coating; it was effective in slowing down the metabolism and delaying softening to day 12.Brazil / Mangifera indica / fruits / storage / postharvest technology / coating / refrigeration / antioxidants / keeping quality / quality Effet d'un enrobage de galactomannane sur les paramètres de qualité physico-chimique et la physiologie de la mangue en post-récolte.Résumé --Introduction.
