25. Nitrogen fertilization effects and phosphorus sources in sabiá (Mimosa caesalpiniaefolia Benth.), subjected to hydric stress. / Efeitos da adubação nitrogenada e fontes de fósforo em sabiá (Mimosa caesalpiniaefolia Benth.), submetido ao estresse hídrico.
Due to the social accountability demanded from university research, this study is related to the challenge of making available development strategies for regionssuch as the semi-arid northeastern regions, which is characterized mainly by its limited soil and climate conditions. The purpose of this work was to assess the behavior of sabiá seedlings (Mimosa c

26. Crescimento e atividade fotossintetica em duas especies de lianas de uma floresta estacional semidecidual
The lianas are copious in natural and man-made clearings and it appears that these forms of life require high irradiance for development and growth. Lianas are rooted in the soil and use other plants, especially trees as support. Since these plants begin their growth on the forest floor, then ascend to the canopy, they can experience extreme differences in r

27. Fluxos de transpiração de tres variedades de cana-de-açucar sob altas condições de demanda hidrica
The quantification of vegetal transpiration is basic for the determination of the water flow of an area and/or watershed. The inquiry concerning transpiration points the stoma as the main point of control of the water flow, thus the efficiency of the use of the water for the varieties can be considered as a species of relation cost/benefit to increase the su

28. Evapotranspiration and maximum transpiration in a high density coffee plantation. / Evapotranspiração e transpiração máxima em cafezal adensado.
Coffee arabica plants are extensively cultivated in tropical regions and it is a crop of great economic importance for Brazil. Currently, it is cultivated in areas with water deficits for which the irrigation is necessary to increase yields and drink quality. To increase irrigation efficiency one needs to know the water consumption of coffee plantation, info

29. Dinamica da remoção de nutrientes em alagados construidos comTypha sp
The study of the use of wetlands it supplies the possibility of treatments of residues of a natural and efficient form, promoting one better exploitation of the environment resources. The project that used the system of wetlands developed in the experimental field of the College of Agriculture Engineering (FEAGRI) had as objective to evaluate the degree of f

30. Avaliação do uso do fluxo de seiva e da variação do diâmetro do caule e de ramos na determinação das condições hídricas de citros, como base para o manejo de irrigação. / Evaluation of the use of sap flow and the variation of stem and branches diameter in the determination of citrus water status, as a base for irrigation.
Uma dificuldade para o manejo adequado da irrigação em espécies de plantas perenes, como por exemplo num pomar, é determinar o momento e a quantidade de água que deverá ser aplicada. Há vários métodos tradicionais de medida de consumo diário de água, assim como indicadores do déficit hídrico, mas cada um apresenta seu grau de dificuldade de uso

31. Caracterização microclimática, ecofisiológica e fitossociológica em uma floresta estacional semidecidual secundária, em Viçosa, MG / Microclimatic, ecophysiological and phytosociological characterization of a secondary semideciduous seasonal forest, in Viçosa, MG, Brazil
A study in the domain of the Atlantic Forest was carried out in ten sites with different slope, aspect and topographic position at the Estação Experimental Mata do Paraíso, in Viçosa, Minas Gerais State, Brazil (20o45 Latitude South, 42o55 Longitude West and an average altitude of 690 m). The spatial and temporal characterization of the photosyntheticall
