| Abstract: The objective of this work was to evaluate the effect of copper use efficiency in soybean cultivars, grown on a typical Ultisol with a high organic matter content, on soil chemical properties and on plant grain yield, nutritional state, and physiological components. The experiment was carried out in greenhouse conditions, in a 5×4 factorial arrangement, with five soybean cultivars (TMG 1066RR, BRS 360RR, NA 6262RR, BMX Turbo RR, and BRS 359RR) and four Cu rates (0, 2, 4, and 8 mg kg-1). Under the studied soil conditions, the DTPA-TEA and Mehlich-1 extractants were efficient in determining available Cu in the soil. Regardless of the cultivars, Cu application increased grain yield (GY), shoot dry weight yield (SDWY), number of pods per pot, GY/SDWY... |

| In the 2000 and 2001 springtime periods, mesozooplankton samples were systematically taken during research cruises devoted to the study of the distribution and abundance of small pelagic fishes in the French part of the Bay of Biscay, NE Atlantic, continental shelf. Simultaneous activities of three enzymes were measured in these mesozooplankton samples, to characterize the main features of ecosystem function at a regional scale. The aim was to assess assimilation rates of carbohydrates, through pyruvate kinase activity, and protein, through trypsin activity, by the mesozooplankton community and the resulting overall productivity, through aspartate transcarbamylase activity. The highest influence on the pelagic environment was the strong difference in the... |

| O estudo teve por objetivo avaliar componentes do crescimento e do estado nutricional de porta-enxertos de limoeiro cravo, em função de doses de nitrogênio, fósforo e potássio via fertirrigação. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 33 + 1, sendo 3 fatores (nitrogênio, fósforo e potássio - NPK), em 3 doses e uma testemunha (sem adubação), com 3 repetições. A unidade experimental foi constituída pela média de dois porta-enxerto (Hipobioto) de limoeiro cravo (Citrus limonia L. Osbeck), cada qual situado em um tubete de 2,8 cm de diâmetro e 12,3 cm de altura, perfurados na base e preenchido substrato composto de casca de Pinus e vermiculita. As doses utilizadas foram constituídas por níveis de N (460; 920 e 1840 mg... |
