Tomato (Lycopersicon esculentum Mill.) fruits, cv. Santa Clara, were harvested at the breaker stage from commercial fields in Brazlândia, Brazil, to investigate the ability of 1-methylcyclopropene (1-MCP) to retard tomato fruit ripening. Fruit without external blemishes were graded for size (diameter = 80±5 mm) and mass (m = 130±10 g), placed inside hermetically sealed boxes, and 1-MCP was applied for 12 hours (T = 22±1°C; RH = 80-85%) at four different concentrations: 0 (control), 250, 500 and 1000 mL.L-1. Fruits were held at ambient conditions (T = 23±2°C; RH 80-85%) for 2 days and then stored inside a cold room (T = 20±1°C; RH = 85-95%). Every 3 days, during a 15-day period, fruits were analyzed for firmness, total soluble solids, titratable acidity,... |

Abstract Pork is the most popular meat in the world. Unfortunately, the selection pressure focused on high meat content led to a reduction in pork quality. The present study used RNA-seq technology to identify metabolic process genes related to pork quality traits and fat deposition. Differentially expressed genes (DEGs) were identified between pigs of Pulawska and Polish Landrace breeds for two the most important muscles (semimembranosus and longissimus dorsi). A total of 71 significant DEGs were reported: 15 for longissimus dorsi and 56 for semimembranosus muscles. The genes overexpressed in Pulawska pigs were involved in lipid metabolism (APOD, LXRA, LIPE, AP2B1, ENSSSCG00000028753 and OAS2) and proteolysis (CST6, CTSD, ISG15 and UCHL1). In Polish... |

Recently, plant growth regulators have been used for various purposes in apples. Methyl jasmonate (MeJA) has significant effects on the physiology, postharvest biology, processing, and chemical composition of apples. In the present study, the effects of MeJAMeJa treatments on the physicochemical quality and bioactive compounds (total antioxidant activity, total phenolics, and total anthocyanins) of 'Fuji' apples were investigated. The following doses of MeJa were used: 0 (control); 1; 120; 2,240; and 4,480 mg L-1. The highest geometric mean diameter, fruit mass, flesh firmness and skin thickness were obtained from the 2,240 mg L-1 MeJA treatment. Fruits harvested from control trees exhibited the highest total soluble solids content (TSSC) and pH, whereas... |

Bacillus subtilis BEB-13bs, a plant growth promoting rhizobacteria, has improved tomato firmness. Since firmer fruits are be expected to be more resistant to spoilage microorganisms and to have a longer shelf-life, root inoculation with this strain could be an alternative to extend tomato shelf-life. Thus, fruit texture-related changes were studied in tomato plants (Lycopersicon esculentum Mill.) inoculated with Bacillus subtilis BEB-13bs. Treatments were: 1) non-inoculated control treatment (CTL); 2) PGPR inoculated treatment (BS13). Evaluation was made at different ripening stages. Pericarp firmness and activity of poligalacturonase (PG), the major cell wall polyuronide degrading enzyme in tomato, were measured. The expression pattern of ripening-related... |

Harvest time is one of the main factors related to guava fruit postharvest losses. It is subjectively determined by fruit size and skin color, without any consensual standardization among the growers. The use of maturity indexes enables growers to know the ideal harvest time according to each market situation. The objective of this work was to determine the maturity indexes to identify the harvest time for guava fruit cv. Kumagai and Paluma. Skin color, fruit firmness, soluble solids, titratable acidity, ratio and ascorbic acid were analyzed. The most adequate maturity indexes for 'Kumagai' guava fruit were skin color and pulp firmness, while for 'Paluma' guava fruit, the best indexes were skin color, pulp firmness, titratable acidity and ratio. |
