“…There are no records in literature on the use of A. nodosum extract for the post-harvest treatment of fruits; however, the use of the extract under field conditions increased productivity and improved the quality of bell pepper, 'Thompson' grape and strawberry fruits, and, for the latter, an increase in size and average weight of fruits was also reported (AMOROS et. al., 2004;ROUSSOS;DENAXA;DAMVAKARIS, 2009;KEATHLEY, 2006). In mangoes, the effects of Biovita® biofertilizer based on A. nodosum were observed in mangoes of the Dashehari cultivar, which presented higher productivity than untreated mangoes (REDDY et al, 2011).…”

-The aim of this study was to determine the effect of Ascophyllum nodosum extract (AN), applied in different doses on the physicochemical characteristics of post-harvest 'Tommy Atkins' mangoes. The selected mango fruits were treated with different extract concentrations (0%, 0.1%, 0.3%, 0.5% and 1.0%) and stored for 12 days at 25±2 °C and 75±5% RH. Every 3 days, fruit mass loss (PM), color angle (Hue) (AH), firmness, pH, titratable acidity (AT), content of total soluble solids in pulp (°Brix) and content of carbohydrates in shell were assessed. The experiments were carried out in CRD in a 5 x 5 factorial arrangement (concentrations x days of storage) with four replications. AN was effective in preventing PM, with a reduction of up to 40.2%, as observed at concentration 0.1% compared to control. There were no differences among concentrations on AH, however, all of them differed significantly from control with higher AH, especially on the 12 nd day. Fruit firmness was lower in control, the pH increased with the storage time and AT decreased. For all these parameters, mangoes treated with the extract differed from control. The pulp sample °Brix increased with the storage time as well as the content of reducing sugars, with consequent reduction of non-reducing sugars in fruit shell. These tests indicate the possibility of using AN as an alternative management in preserving mangoes in the post-harvest stage. Index Terms: Mangifera indica, fruit preservation, shelf life.

“…In fact, these foods can help reduce the risk of chronic, degenerative and oxidative-stressmediated diseases, such as cancer and cardiovascular and neurodegenerative diseases (Roussos et al 2009). As a result, attention is now also directed towards many small fruits that are considered to be a source of organic and inorganic nutrients and metabolic-regulating factors.…”

“…In addition, flavonoids also contribute to the quality characteristics of fresh and processed food products including astringency, texture, taste and colour (Vvedenskaya & Vorsa 2004). Preharvest factors such as the plant genetic background, the environmental conditions during plant growth, the cultural practices employed and the stages of fruit ripening, all influence the synthesis of phenolic compounds (Ka¨hko¨nen et al 2001;Ferreyra et al 2007) and their antioxidant capacity (Roussos et al 2009), with ripening stages being even more relevant when immature berries are used, for example, cranberries in the juice industry (Ç elik et al 2008).…”

The accumulation patterns of phenolic compounds during fruit growth and ripening of Berberis buxifolia and their correlations were studied to determine the optimal time and conditions needed to obtain maximum phenolic content. Anthocyanin content increased from 1.7 to a maximum of 752.7 mg ×100 g(1 FW at the end of ripening, while the flavonoid content was maximal in unripe fruits [604.0 mg (')-catechin equivalents ×100 g(1 FW]. Total phenolic compounds decreased from 968.1 to a minimum of 746.3 mg gallic acid equivalents ×100 g(1 FW just as soluble solids started to accumulate; a maximum of 1522.9 mg gallic acid equivalents ×100 g(1 FW was attained at the end of ripening. Both variables (1,1-diphenyl-2-picrylhydrazyl scavenging effect and reducing power) were maximum in unripe fruits, and decreased during the ripening period, although the 1,1-diphenyl-2-picrylhydrazyl scavenging effect increased again towards the end of this period. The accumulation patterns of phenols varied depending on the specific group of compounds considered, and could be correlated with fruit quality.

“…Resultados que concuerdan con lo encontrado en esta investigación fueron reportados en fresa, pues Roussos et al (2008) no encontraron efecto significativo de la aplicación de reguladores de crecimiento sobre los SST, lo cual coincide con lo encontrado por Casierra-Posada y Salamanca (2008) en la misma especie bajo la aplicación precosecha de ácido giberélico y nitrato de calcio. Amézquita et al (2008) también encontraron que diferentes dosis de ácido giberélico aplicados en precosecha a frutos de uchuva no afectaron significativamente el contenido de SST.…”

El objetivo de esta investigación fue evaluar el efecto de la aplicación exógena de ácido giberélico sobre la producción y calidad poscosecha de tomate híbrido Ichiban. Se utilizó un diseño completamente al azar con seis tratamientos correspondientes a diferentes dosis de ácido giberélico (0, 1, 10, 100, 1.000 ó 10.000 mg L -1 ). El ácido giberélico se aplicó de forma localizada en el momento en que cada racimo formó sus frutos, por tanto, se hicieron ocho aplicaciones (ocho racimos/planta), cada fruto recibió una sola aplicación. Al momento de la cosecha se midió la producción y posteriormente el comportamiento poscosecha durante 21 días. Los resultados indicaron que la aplicación de 100 mg L -1 de ácido giberélico generó la mayor producción de calidad extra, primera, un considerable rendimiento total y una baja producción de las calidades correspondientes a frutos de menor tamaño (cuarta, tercera y segunda), lo cual hace que sea la dosis que más favorece la producción de frutos de mayor tamaño. La dosis de 10.000 mg L -1 de ácido giberélico no favorece la producción de tomate, debido a que generó la menor producción total, extra, primera y altas producciones de los frutos de menor calidad (tercera y cuarta). La aplicación de ácido giberélico no produjo un efecto negativo en la calidad poscosecha de los frutos de tomate, pues no cambió significativamente la pérdida de peso, los sólidos solubles totales y la firmeza de los frutos de tomate.Producción y calidad poscosecha de tomate (Solanum lycopersicum L.) larga vida sometido a la aplicación de ácido giberélicoYield and postharvest quality of long life tomatoes (Solanum lycopersicum L.) submitted to an application of gibberellic acid ABSTRACTThe objective of this research was to evaluate the effect of an exogenous application of gibberellic acid on production and postharvest quality of the tomato hybrid: Ichiban. A completely randomized design with six treatments for different doses of gibberellic acid (0, 1, 10, 100, 1,000 or 10,000 mg L -1 ) was used. The gibberellic acid was applied in a localized manner at the time that each cluster had its fruits formed, therefore, eight applications were done (eight clusters/plant), but each fruit received one application. At the time of harvest, production was measured, along with the postharvest behavior for 21 days. The results showed that an application of 100 mg L -1 gibberellic acid resulted in increased production of extra quality, first; a considerable overall yield and a low production of quality corresponding to fruits of smaller sizes (fourth, third and second), which makes it the most favorable dose, producing larger fruit. The dose of 10,000 mg L -1 gibberellic acid is not conducive to tomato production because it generated the lowest total production, extra, first; and high yields of lower quality fruit (third and fourth). The application of gibberellic acid did not produce a negative effect on postharvest quality of tomato fruits; and did not significantly change weight loss, total soluble solids or firmne...
