Crop evapotranspiration (ETc) was measured as evaporative heat flux from an irrigated acid lime orchard (Citrus latifolia Tanaka) using the aerodynamic method. Crop transpiration (T) was determined by a stem heat balance method. The irrigation requirements were determined by comparing the orchard evapotranspiration (ETc) and T with the reference evapotranspiration (ETo) derived from the Penman-Monteith equation, and the irrigation requirements were expressed as ETc/ETo (Kc) and T/ETo (Kcb) ratios. The influence of inter-row vegetation on the ETc was analyzed because the measurements were taken during the summer and winter, which are periods with different regional soil water content. In this study, the average Mc values obtained were 0.65 and 0.24 for the summer and winter, respectively. The strong coupling of citrus trees to the atmosphere and the sensitivity of citrus plants to large vapor pressure deficits and air/leaf temperatures caused variations in the Kcb in relation to the ETo ranges. During the summer, the Kcb value ranged from 0.34 when the ETo exceeded 5 mm d(-1) to 0.46 when the ETo was less than 3 mm d(-1). (C) 2011 Elsevier B.V. All rights reserved.

The Independence of Brazil was proclaimed in September 1822 after two years during which constituent deputies elected on both sides of the Atlantic and gathered in Lisbon endeavoured to achieve unification with the former Portuguese metropoli. Due to the failure of these attempts a Constituent Assembly settled in independent Brazil in July 1823. Those two parlamentary experiences - the first to take place in the Portuguese dominions - were strongly influenced by the decisions adopted in Cadiz (1810-1814), and in Madrid (1820-1823), and by the independentist processes developed at the time in Spanish America. This work aims at observing that influence on the decisions adopted in Lisbon and Rio de Janeiro vis-a-vis the autonomical reivindications of several Brazilian provinces.
