| Caléndula (Calendula officinalis L.) es una planta herbácea anual que destaca por los usos medicinales de sus capítulos (flores). En esta especie se ha demostrado diversidad genética y de composición química entre variedades. En México no se cultivan diferentes variedades ni se ha investigado la variación posible en el rendimiento de capítulos, concentración de flavonoides y carotenoides en función de la variedad y de cortes, como es el efecto causado por cosechas continuas de los capítulos florales. El objetivo de este estudio fue determinar el rendimiento, concentración de flavonoides y carotenoides en seis variedades de caléndula aquí seleccionadas, cuyos capítulos fueron cosechados a lo largo de siete cortes en 2010 y de nueve cortes en 2011, de... |

| ABSTRACT One of the factors that hinder the usability of Cerrado fruits is their perishable nature, requiring industrial processing to ensure prolonged shelf life. This study aims to determine the optimal foaming agent for industrial processing of this fruit, and to evaluate the physicochemical characteristics and antioxidant activity of dried cagaita powder (Eugenia dysenterica DC) in foam layers at temperatures of 40, 50, 60, and 70 °C. The effectiveness of three foaming agents at various concentrations were tested, and suitable agents were identified based on a factorial analysis of density, expansion, and stability. The physicochemical characteristics of the powder, along with its vitamin A and C and total carotenoid content and antioxidant activity,... |

| Abstract Psidium cattleyanum Sabine is an Atlantic Forest native species that presents some populations with red fruits and others with yellow fruits. This variation in fruit pigmentation in this species is an intriguing character that could be related to species evolution but still needs to be further explored. Our goal was to provide genomic information for these morphotypes to understand the molecular mechanisms of differences in fruit colour in this species. In this study, we performed a comparative transcriptome analysis of red and yellow morphotypes of P. cattleyanum, considering two stages of fruit ripening. The transcriptomic analysis performed encompassing leaves, unripe and ripe fruits, in triplicate for each morphotype. The transcriptome... |

| 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 Fertilizers supply in the appropriate period and dose is important to obtain satisfactory production. In this research we studied the effect of different split applications and doses of nitrogen in top dressing on the production of the carrot and the physicochemical characteristics of the roots. Nine treatments, resulting from a factorial of 4x2+1 (control without nitrogen fertilization), were evaluated in the randomized blocks experimental design, with four replications. The first factor were four nitrogen (N) doses in top dressing (60, 90, 120 and 150 kg ha-1) and the second were two forms of splitting [three equal applications (1/3+1/3+1/3 of the dose) and one with increasing proportions (1/6+2/6+3/6 of the dose) applied 15, 30 and 50 days... |

| ABSTRACT The aim of this study was to evaluate the effect of salicylic acid (SA) application on pre-transplant acclimatization of native populations of tomato. SA is a growth regulator that modifies plant growth and development by inducing changes in cell processes, physiology and morphology. Five populations of native tomato were sown in polystyrene trays. Peat moss was used as substrate and plants were maintained at field capacity continuously. After emergence, seedlings were applied during three weeks with different concentration of SA (0.0, 0.01, 0.1, 0.5 and 1.0 μM). A completely random experimental design was used with five replications per treatment. The growth parameters evaluated were height, stem diameter, number of leaves, hypocotyl length,... |

| ABSTRACT The nutritional value of carrot is determined by the content of total sugars and monosaccharides, carotenoids and vitamins, including vitamin C, in its roots. In 2009-2011, field experiments were carried out concerning the effect of biostimulating preparations applied during the carrot vegetation period on selected nutrients of its roots (total sugars, monosaccharides, carotenoids and vitamin C). Two biostimulants were foliarly applied in doses of 2 or 3 L ha-1 on various dates. Kelpak SL and Asahi SL: one, two or three applications; where, second and third applied at 2-week interval, additionally Kelpak SL: one application at 4-leaf phase, followed by additional application after 4 weeks. The field study was conducted in a randomized block design... |

| Исследованы количественный и качественный состав каротиноидов в различных органах мидии Mytilus galloprovincialis Lmk. (гонадах, жабрах, гепатопанкреасе, остальных тканях), во взвешенном веществе как кормовой базе мидий и в фекалиях мидий. Показано, что гонады, жабры и остальные ткани содержат 5 основных каротиноидов, качественный состав которых определен. Гепатопанкреас содержит от 9 до 15 каротиноидов, но не все пигменты идентифицированы. Проведены предварительные балансовые исследования потока каротиноидов из пищи мидии в биоотложения. Рассчитана усвояемость каротиноидов мидией. |

| Рассчитаны пометы суточного баланса БАВ (каротиноидов и а-токоферола) культивируемых мидий в зависимости от сезона. Все элементы баланса по БАВ имеют сходную структуру. Максимальные траты вещества приходятся на дыхание, а доля трат на соматический рост превышает долю трат на генеративный рост. Усвоение а-токоферола превышает усвоение каротиноидов, что свидетельствует о высокой потребности мидий, проходящих преднерестовую стадию, в витамине Е, как и в каротиноидах. Годовые величины эффективности использования каротиноидов на продукцию черноморских мидий (К2) изменяются от 0,03 до 0,56, для а-токоферола коэффициент К2 составил 0,01 в летний период. |

| The green microalgae Dunaliella genus is known for the production of high added value molecules. In this study, strain AL-1 was isolated from the Sebkha of Sidi El Hani (Sousse, Tunisia). This isolate was identified both morphologically and genetically via 18S rRNA gene sequence as a member of the genus Dunaliella. Strain AL-1 was found to be closely related to Dunaliella salina, Dunaliella quartolecta and Dunaliella polymorpha with more than 97% similarity. Response surface methodology was used to maximize carotenoid production by strain AL-1 by optimizing its growth conditions. The highest carotenoid content was obtained at salinity: 51, light intensity: 189.89 μmol photons·m−2·s−1, and nitrogen: 60 mg·L−1. Proteomic profiling, using two-dimensional gel... |

| The herbicide bentazon (CASRN 25057-89-0) is extensively used in agriculture in Brittany (France) to replace atrazine. Bentazon is not readily adsorbed by soil and therefore it enters adjacent freshwater ecosystems, making its way to estuarine and marine waters areas. Information regarding its effects on marine ecosystems is scarce. Phytotoxicity assessments were conducted in the laboratory on the common diatom Chaetoceros gracilis using both the active ingredient and its formulated product (Basamais). The 3 day EC50 Using cell counts were, respectively, 150 mg/L and 60 mu g/L for bentazon active ingredient and for bentazon-formulated while cellular volume was increased. Although bentazon is known as a photosystem II inhibitor, it produced an increase of... |
