“…According to the authors, maintained TTA levels might affect a fruit's final sensory quality. Paula et al (2007) also observed increased acidity initially, and, later, decreasing acidity in figs treated with fungicide and calcium chloride, which they attributed to fruit quality improvement through mainly lower weight loss and higher firmness.…”

The fig is one of the most perishable fruits during the postharvest phase, which has prompted studies to evaluate the effects of substances applied on figs after harvest in order to extend their postharvest life. The aim of this work was to evaluate the effects of different concentrations of 1-methylcyclopropene (1-MCP) on the postharvest quality of Roxo de Valinhos figs. The research was conducted by applying 4 concentrations of 1-MCP (0 -control, 5, 10, and 20 µg L -1 ) on figs, after which the fruits were evaluated at five different storage times (0, 4, 8, 12, and 16 days). The results showed that 20 µg L -1 of 1-MCP provided the best fruit firmness at day 12 after harvest. The 1-MCP treatments did not improve the total amount of total soluble solids (TSS), but we observed higher amount of total solids from 12 to 16 days of storage. Higher acidity was observed in the figs without a 1-MCP treatment at 8 days of storage and with 20 µg L -1 of 1-MCP after 12 days of storage. 1-MCP did not affect fruit weight loss. The figs treated with 1-MCP showed promising and rising values of firmness, acidity, and TSS at the highest dose. The TSS concentration tended to increase at the higher doses. As a result, it could be interesting to assay this substance with applications with higher concentrations than those used in the present study.

However, 1-MCP applications on fruits may not always have similar results on the postharvest quality since its effect has been shown to vary according to the climacteric fruit species, cultivar, maturation and ripening stages of the fruit, and 1-MCP application forms (Freiman et al., 2012;Sozzi et al., 2005; Watkins, 2006;Zhang et al., 2017).There are few reports on the postharvest behavior of figs treated with 1-MCP. Gözlekçi et al. (2008) showed that 10 µg L -1 of 1-MCP slowed the softening of Bardakci figs and retained fruit firmness during...

This work aimed to evaluate the post-harvest quality of fruits of the fig cultivar ‘Roxo de Valinhos’ in two pruningtimes and three ripening stages, under the edaphoclimatic conditions of the semiarid region of the Piauí state.The experiment was carried out in the educational orchard of the Federal University of Piauí, Campus ProfessoraCinobelina Elvas, Bom Jesus, Piauí, Brazil. A completely randomized design (CRD) was used, with 4 replications,in a 2 x 3 factorial scheme, with treatments corresponding to two pruning times (April 2018, of the rainy season,and December 2018, the beginning of the rainy season) and three fruit ripening stages (Green Intermediate,and Ripe), using 5 fruits per experimental plot and performing chemical analyzes in triplicate. The pruningcarried out in April (end of the rainy season) significantly influenced the post-harvest quality of the fig fruits, withgreater weight (34.17 g fruits), transverse diameter (42.21 mm), luminosity (57.92°), and HUE angle (80.73° ), whencompared to the pruning carried out in December (beginning of the rainy season), with weight (26.58 g fruits),transversal diameter (39.83 mm), luminosity (52.53°), and HUE angle (73.60°). The cultivation of fig trees in thesemiarid region of Piauí showed promising results with the anticipation of the crop cycle with pruning performedin the dry season.

Aiming to evaluate the postharvest quality of ‘Roxo de Valinhos’ fig fruits grown in semi-arid conditions, this experiment was carried out in November, 2014, where fig fruit variety ‘Roxo de Valinhos’ were harvested from plants located at the didactic orchard of the Federal Rural University of Semi-Arid (UFERSA), Mossoró-RN, Brazil. Fruits were randomly harvested from 30 fig plants, spaced 2 m x 1.5 m, with 2 years old, according to three the fruit development stages (50%, 75% and 100% mature). The fruits were analyzed in Postharvest Physiology Laboratory, where the physical and chemical characteristics were evaluated, using 10 fruits for each stage. The evaluated characteristics were: weight, length, diameter, firmness, soluble solids, pH, titratable acidity and vitamin C. For the physical characteristics, fruits 100% mature presented the best results for weight, length and diameter, except for firmness which in fruits 50% mature presented the best results. For the chemical characteristics, only the soluble solid variable was signiicant and fruits 100% mature showed the best result, in this way, the fig tree ‘Roxo de Valinhos’ achieved the postharvest fruit quality and is viable for the semiarid region of the Rio Grande Norte State.
