Los incendios constituyen disturbios de muy diverso origen y variadas implicancias. Además de los efectos sobre la vegetación, pueden afectar los componentes y las propiedades de los suelos. Las modificaciones en los suelos, a su vez, suelen incrementar los procesos de erosión, de transporte de sedimentos y, como consecuencia de lo anterior, también de inundaciones. La mayor parte de los estudios sobre los impactos edáficos del fuego han tenido como objeto los efectos sobre la materia orgánica y otras propiedades químicas y, en menor medida, los efectos sobre las propiedades físicas y mineralógicas. El propósito de este trabajo fue revisar el estado del arte en la literatura sobre estos últimos efectos, que han sido menos explorados. Se ha encontrado que... |

ABSTRACT Kale is a vegetable that has high nutrition content, and balanced fertilization is essential to ensure high yield and quality of agricultural products. Curly kale, less known than regular leaf kale, is a new possibility for consumption. However, little is known about the influence of the type of fertilization on nutritional characteristics. This study aims to evaluate the influence of using organic fertilizers on the productivity, microbiological, and physico-chemical characteristics of Darkibor hybrid curly kale. The treatments consisted of three sources of organic fertilizers, one of organomineral fertilizer, and the control (without fertilization). The highest productivity was observed for kale that was treated with fertilizer in the... |

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,... |

Las atmósferas controladas alargan la vida en estante del tomate, permitiendo su cosecha en estados de madurez más avanzados y a su vez afectando su calidad. El objetivo de este experimento fue estudiar los efectos que atmósferas controladas con bajas concentraciones de oxígeno y libres de dióxido de carbono y etileno, producen sobre el color, la firmeza y los principales componentes del sabor de frutos de tomate cultivar Diva. Durante abril de 1998, frutos cosechados con grado de color 3 (USDA) en INTA Balcarce (Argentina) fueron almacenados en frascos herméticos de 3 L a 12°C durante 36 días. El diseño fue completamente aleatorizado con tres repeticiones. Cada frasco poseía cuatro frutos, los que constituyeron la unidad experimental. Los tratamientos... |

The shell color of the Mollusca has attracted naturalists and collectors for hundreds of years, while the molecular pathways regulating pigment production and the pigments themselves remain poorly described. In this study, our aim was to identify the main pigments and their molecular pathways in the pearl oyster Pinctada margaritifera—the species displaying the broadest range of colors. Three inner shell colors were investigated—red, yellow, and green. To maximize phenotypic homogeneity, a controlled population approach combined with common garden conditioning was used. Comparative analysis of transcriptomes (RNA-seq) of P. margaritifera with different shell colors revealed the central role of the heme pathway, which is involved in the production of red... |

Abstract : The objective of this work was to evaluate the effect of (S)-cis-abscisic acid (S-ABA) application at different ripening stages, in increasing phenolic compounds and color of berry and juice of 'Isabel' grape (Vitis labrusca). The evaluated treatments were: control, without S-ABA application; 400 mg L-1S-ABA applied 7 days before veraison (DBV) + 400 mg L-1S-ABA at 35 days after first application (DAFA); 400 mg L-1S-ABA applied at veraison (V) + 400 mg L-1S-ABA at 35 DAFA; and 400 mg L-1S-ABA applied 7 days after veraison (DAV) + 400 mg L-1S-ABA at 35 DAFA. There was no difference among treatments regarding the physical characteristics of berries and clusters, as well as total polyphenols in berry and juice. However, there was an increase in... |

Chickpea is a well recognized source of vegetable protein, especially in underdeveloped areas of the world. Mexican chickpea is highly priced in the international market due to its desired quality. The Northwest of Mexico, especially Sonora and Sinaloa, are also recognized for the quality of chickpea, where a high percentage of the annual production is placed in the international market. Among the various characteristics of high-quality chickpea, color is one of the most important, since it influences both: the selection of new improved varieties at the experimental research stations, and also the price at the international market. The purpose of this study was to evaluate two objective instrumental methods of color determination as related to sensory... |

We conduct a within-sample test of hypothetical bias and parameter equality between a hypothetical stated choice (SC) experiment using pictures and a real choice (RC) experiments using products. With exception of the none-of-these alternative-specific dummy, we cannot reject parameter equality between the two datasets. However, when we estimate the models separately with no parameter restrictions, the SC experiment gave WTP estimates that were approximately 50 percent higher and marginal WTP estimates that were almost two times as high as the corresponding estimates from the RC experiment. However, even though the monetary value of the WTP disparity was large, the disparity between the WTP estimates from the two data sets was not statistically significant. |

This study aimed at evaluating the effect of different fasting periods and water spray during lairage on the quality of chicken meat. A number of 300 male Ross broilers were reared up to 42 days of age, and submitted to four pre-slaughter fasting periods (4, 8, 12, and 16 hours) and sprayed with water or not during lairage. Deboned breast meat was submitted to the following analysis: pH, color, drip loss, water retention capacity, cooking loss, and shear force. There was a significant effect (p < 0.05) of fasting period on meat luminosity was significantly different, with the highest value obtained for 4-hour fasting, whereas no difference was found among the other fasting periods. Meat pH values were different among fasting periods when birds received... |

The aim of this study was to evaluate the viability of the use of spent laying hens' meat in the manufacturing of mortadella-type sausages with healthy appeal by using vegetable oil instead of animal fat. 120 Hy-line® layer hens were distributed in a completely randomized design into two treatments of six replicates with ten birds each. The treatments were birds from light Hy-line® W36 and semi-heavy Hy-line® Brown lines. Cold carcass, wing, breast and leg fillets yields were determined. Dry matter, protein, and lipid contents were determined in breast and leg fillets. The breast and legg fillets of three replicates per treatment were used to manufacture mortadella. After processing, sausages were evaluated for proximal composition, objective color,... |

The objective of this study was to evaluate the effect of different supplementation levels of Rhodocyclus gelatinosus biomass on the performance and pigmentation of broilers. Cobb broilers were raised in pens and were fed a sorghum-based diet until 35 days of age. At the 36th day of age, ninety-six birds were randomly distributed to four treatments consisting of experimental diets with different supplementation levels of Rhodocyclus gelatinosus biomass (0, 75, 150 and 300 ppm) added to the finisher basal diet, which were given for seven days. A completely randomized experimental design was used, with four treatments, four replicates and six broilers per parcel. Birds and diets were weighed at the 36th and at the 42nd day of age for performance analysis.... |

ABSTRACT The present study was carried out to investigate the influence of freezing-thawing cycles (0, 2, 4 and 6) on lipid oxidation and myowater contents and distribution. Nine replicates of chicken breast meat samples were used for each cycle. Lipid oxidation was determined by measuring peroxide value, and malondialdehyde (MDA) concentrations, which reflect thiobarbituric acid reactive substance (TBARS). Color was determined with a digital colorimeter. Muscle moisture contents were determined by drip loss and thawing loss, water holding capacity, and nuclear magnetic resonance (NMR). The results showed that, as the number of freeze-thaw cycles increased, meat redness decreased and MDA and peroxide values increased. Drip loss and thawing loss tended to... |

ABSTRACT The dual-stage sugar substitution technique (D3S) was used to induce sugar replacement in mango. It involved two stages, in which high-calorie sugars were partially removed from the fruit samples in the first stage and, in the second one, low-calorie sugar was incorporated into the mango. Ultrasonic waves can be applied in one or both stages and their use was also evaluated in this study. Results showed that submitting samples to ultrasonic waves (25 kHz) in both stages and their immersion in Stevia-based solution (250 or 500 g kg-1) in the second stage for 10, 20 and 30 min of processing gave higher water loss during the process, while greater solids gain could be achieved by applying ultrasound only in the first stage. Samples were also... |
