| It is an endangered tree fern that grows in mixed umbrophylus forests in the tropics. Sterilized spores were germinated at 25 ± 2ºC under a 16-hour photoperiod, in Dyer and MS medium supplemented with 0 to 5% sucrose. The germination was lower with the addition of sucrose. Dry mass was higher in 30-day-old gametophytes cultivated in Dyer medium with the addition of 3 to 5% of sucrose. The dry mass decreased in 30-day-old gametophytes cultivated in Dyer and MS media without sucrose and in MS medium with the addition of 4 or 5% of sucrose. The effect of different irradiance on the germination and early gametophyte development of D. sellowiana was analyzed in the autumn of 1998 (May until July). Conical flasks containing spores were kept over a period of 49... |

| ABSTRACT This study was conducted to investigate the effects of nutrient and salinity concentrations on the quality of deepflow technique hydroponic system cultivated cherry tomatoes (Lycopersicon esculentum Mill ‘Unicorn’). The conditions were: (1) control (NS-1 × nutrient Solution, Electrical Conductivity – EC: 2.5 mS∙cm–1); (2) 2 × NS (2 × NS-Double NS, EC: 5 mS∙cm–1); (3) NS + 4.23 mM NaCl (NaCl-Sodium Chloride, EC: 5 mS∙cm–1); and (4) NS + 13.70 mM Sea Water – SW (EC: 7.5 mS∙cm–1). NS + 13.70 mM SW treatment showed the lowest fresh weight loss. Visual quality as well as shelf life was the longest in NS (1 × nutrient solution) treated tomato fruits. The longest shelf life at 5 °C, 11 °C, and 24 °C were 21, 16, and 8 days, respectively, in NS (1 ×... |

| The effect of temperature, concentration and contact time on the fungicidal effect of clove oleoresin dispersed in a concentrated sugar solution at 21 and 37ºC, and clove oleoresin at 0.2 to 0.8% (v/v) was studied. The test microorganisms were Candida albicans, Penicillium citrinum, Aspergillus niger and Trichophyton mentagrophytes. The fungicidal effect was enhanced at 37ºC; at this temperature short contact times (e.g. 1 min.) were enough to eliminate a microbial inoculum of 10(6) c.f.u./ml of C. albicans. Although clove oleoresin caused important lethal effect, P. citrinum and A. niger were more resistant. After 60 minutes, clove oleoresin dispersed (0.4% v/v) in concentrated sugar solution caused a 99.6% reduction of the initial population (10(6)... |

| Guava is one of the most complete and balanced fruits in in terms of s nutritional value. Highly perishable, due to its intense metabolism during ripening, its shelf life can reach 3 to 5 days under room temperature. The firmness of the green and mature fruits is due mainly to the pectin polymers. The loss of firmness during the guava ripening is due to hydrolytic enzyme activity, which promotes intense solubilization of the cell wall pectins. Given the above, with the purpose of trying to explain the rapid firmness decrease, the centesimal composition and sugar fraction of the guava fruit were determined during ripening at room temperature. The guavas were picked at the half-mature stage and stored for 8 days at 22 ± 1 ºC and 78 ± 1% relative humidity.... |

| This study evaluates the physical and physicochemical properties of three sugary cassava (Manihot esculenta Crantz) landraces: São Francisco Bag 3, Manicueira 62, and Castanhal Iracema. These three landraces showed high estimated productivity (≥3.93kg plant-1) and had a high sugar content (≥3.92g 100g-1 of root), making them viable for use in syrup production, especially the São Francisco Bag 3 landrace (4.76g 100g-1). The Manicueira 62 landrace had the highest starch content (4.40g 100g-1). The three sugary cassava landraces exhibited high levels of cyanide (>195mg kg-1), indicating the need for processing prior to consumption. |

| We investigated effects of sugar solution on adult longevity, progeny production and progeny sex ratio of Aphidius ervi in the presence and absence of host aphids. When female parasitoids were provided with 50% glucose–fructose solution in 1 : 1 ratio, they lived approximately twice longer than those provided with distilled water, irrespective of host aphid provision. The same effect of sugar solution was also observed on progeny production. When the parasitoid was fed sugar solution, its lifetime progeny production approximately doubled in comparison to that provided with water, whereas daily progeny production did not differ. Total number of female progeny did not differ between adult female provided with water and sugar solution, but significantly... |

| Mudanças ocorridas na economia mundial, como liberalização de mercados e formação de blocos, têm exigido que países em desenvolvimento, como no caso do Brasil, acompanhem tais transformações principalmente no que se refere à busca por produtos diferenciados e de maior qualidade. Diante disso, o setor açúcar iniciou um processo de reestruturação produtiva, visando estimular a modernização e, com isso, ampliar sua competitividade no comércio internacional. Considerando a importância desse setor para a economia brasileira, no que se refere à participação no PIB e na geração de divisas, objetivou-se neste trabalho avaliar a competitividade das exportações brasileiras de açúcar, no período de 1990 a 2004. O modelo teórico utilizado esta fundamentado na Teoria... |

| Currently, Brazil is the greatest worldwide producer and exporter of sugar. Therefore, it is expected better defined forms to restrict high costs, which are normally present in many of the factors involved in the process of production and product commercialization. Under that context, this study searched to characterize the distribution process of the sugar produced in State of São Paulo, indicating in a summarized manner, the main agents involved within the sector, the flow observed by the product until its final delivery and the evolution of transport prices and final prices of the product during the months of the year. The method used to conduct this research was based on primary data survey and on the application of specialized econometric models. In... |

| The various assessments of the effects of a liberalization of world sugar markets are largely inconsistent. One cause seems to be the modeling of the EU supply response. We investigate three possible linkages between production quota sugar and the out-of-quota or "C" sugar supply: i/ the existence of fixed costs covered by the in-quota sugar; ii /the "overshooting" behavior as prevention against poor yields; iii/ the production of C sugar as "reference building" in view of expected reforms. Modeling these effects results in the introduction of an implicit cross-subsidy between in quota sugar and C sugar. The resulting specification is included in a detailed model of EU agricultural sector so as to account for intersectoral linkages. We simulate the effects... |
