The physical and biotic characteristics of a watershed have fundamental importance in the hydrological cycle processes, influencing the infiltration, the runoff, evapotranspiration and surface and subsurface flows. The soil erosion is directly influenced by surface hydrological processes and land management practices, through the sediment production, transport and deposition. In this work the spatial distribution of flow was analyzed in the Barro Branco watershed by SWAT (Soil and Water Assesment Tools) model. This watershed, with 6km2 is inserted in the Northwest Region of Rio de Janeiro State, Brazil. The KOPPEN (1948) climatic classification is Aw, tropical climate with dry winters. The predominant soils are Gley soils and Ultisols. The land use and land cover are divided into: grazing, altered natural vegetation and bare soil. The hydrological processes modeling at catchment scale is an important tool for streamflow simulation. In order to carry out the simulations, the model employs a spatial databank of basin, made up of geographical, pedological, hydrological and climate data, as output data the model generates tables and maps. It was observed that, before calibration, the minimum flows estimated were below those observed, but the peak flows were overestimated. After calibration, the minimum flows had better correlations, while the peak flows were underestimated. The simulation results were compared to streamflow experimentally data observed in 2008. The Nash-Suctlife Efficiency Coefficient (NS), factor regression (R²) and PBIAS was adopted in order to validate the model prediction. The main statistical indices showed significant improvement after calibration and remained satisfactory after validation. Being the NS after calibration of 0.7 and 0.5 after validation; R² Coefficient obtained after calibration was 0.5 and after validation 0.7, finally, the PBIAS calibrated was 12.7 and validated, 13.02. The model was sensitive to the parameters for the soils, first the entire amount of capacity of available soil water to the basin was converted in runoff. However, once the parameters that conditioned infiltration were calibrated, the simulated flow approached significantly to observed data. The SWAT model was able to simulate streamflow in Barro Branco watershed, since there were not many gaps in the monitored data, and also being able to simulate data from other periods for which the parameters were not adjusted.

Ornamental fruit crops present high use plasticity and can be appreciated as landscape plants, foliage and potted plants. However among these several uses the ornamental minifruits are an interesting novelties. The characterization and identification work was carried out in pineapple, banana and citrus genebanks with 628, 226 and 800 accessions respectively and several wild varieties with very small and attractive fruits were selected. They are differentiated miniature copies of the edible fruits. Several evaluations have been done in the last years to determine the traits and the use of these structures to ornamental market. These miniatures can be used in floral arrangements with a beautiful and original effect and can occupy a differentiated market. Some of these aterials were recommended to use directly like ornamentals and the other ones were selected to ornamental breeding programs to generate new varieties. Five hybrids of pineapple were selected with syncarp less than 5 cm, crown/syncarp next to 1 and crown ength less than 4,50 cm with colour ranging from olivegreen to dark-pink. In regard to banana six hybrids from Musa acuminata ssp zebrina × híbrido de M. ornata × M. velutina crossing (RM 09, RM 33 e RM 37 and RM 38) were selected. All of them presented very small fruits with length less than 6 cm, number of fingers around 10 and colours ranging from brown-purple to olive-green. From citrus germplasm four genotypes Chinotto’, C. amblycarpa, ‘Calamondin’ e a tangerine ‘Sunki’ were recommended. The small fruits presented length and diameter less than 3,5 cm with beautiful colours, predominantly oranges and one variety like ‘Calamondin’ with variegated fruits. New hybridisations and evaluations have been done aiming some special traits in these minifruits, including post harvest durability.
