The knowledge about the interaction between mechanical pruning and soil organic amending is still scarce. This study aimed to examine the effects of the interaction between these two practices on wine quality. Syrah grapes from two trial fields in Portugal subjected to two different pruning systems (mechanical pruning; hand spur pruning) and five different organic amendment treatments (control, biochar, municip...
The interaction of mechanized pruning systems and soil organic amendment can affect vine vegetative and reproductive growth. However, since organic amendments supply several mineral elements, namely heavy metals, this study aimed to understand the effects of the interaction between these two practices on the mineral composition of wine. Two field trials were implemented in ‘Syrah’ vineyards in two Portuguese wi...
Aim: The interaction of mechanized pruning systems and soil organic amendment can increase vine productivity. However, since the increase in p roductivity may affect grape composition, this study aimed to understand the effects of the interaction between these two practices. Methods and materials: Two field trials were implemented in Shiraz vineyards in two different wine regions. Mechanical hedge pruning was c...
The effects of fully mechanized pruning systems on physiology, vigor and yield of grapevines have been studied for more than forty years and are an interesting way to reduce production costs. Organic amending of vineyard soil is a way to increase vine productivity. Thus, this study aims to understand the effects of the interaction between these two practices, on vine growth and productivity. Two trial fields we...
This article presents the impact that the changes in the thoughts of philosopher György Lukács in the early 1930s had on his intellectual itinerary. In addition to highlighting the meaning of all his post-1930 production, the article attempts to show how – and for what reasons – the later thoughts of Lukács adopt the word ontology to express the core of Marx’s philosophy.; O presente artigo visa apresentar o im...
This study aims to characterise the chemical compositions and sensorial profiles of wines made with Syrah grapes over two harvest seasons (first and second semester), over in different calendar years, from vines on two different rootstocks (1103P and IAC 313). Wine chemical composition and sensory profile were influenced by both rootstock and harvest season. Syrah wines on IAC 313 were favoured with higher conc...
The northeastern region of São Francisco Valley is the third largest wine producer in Brazil, differentiated by the production of at least two harvests per year, generally in the first and second semesters, respectively. The productive cycle of the vine in the first semester is higher than in the second semester, mainly due to differences in temperature, with maximum and average temperatures of approximately 30...
Resenha do livro "Abaixo a família monogâmica!", de autoria do filósofo Sérgio Lessa.
The evaluation of shoot density and basal leaf removal effects on canopy structure, canopy microclimate and on vigour and vegetative growth was carried out during 3 years (2004 to 2006) on ‘Alfrocheiro’ vine variety, at Dão Delimited Region, Center-North of Portugal. Three different shoot densities were assayed (at G stage of Baggiolini scale): control (D1), 18 shoots.m-1 row (D2) and 12 shoots.m-1 row (D3). At...
A study was carried out during two years (2004 and 2005) at Bairrada Delimited Region (littoral/centre of Portugal) with the white cultivar “Fernão Pires” for the evaluation of the effects of tillage application in a non-irrigated commercial vineyard with a long term natural cover crop. In the two years of the experiment, during the growing season the climate was dry, especially in 2005. Consequently, a moderat...
