1. Influência de fatores climáticos na dispersão aérea de Phakopsora euvitis Y. Ono na cultura da videira.
RESUMO A ferrugem da videira, uma das doenças mais importantes de Vitis spp., é manejada no Brasil seguindo um programa de calendário de pulverização de fungicidas. Apesar da utilização de fungicidas, as perdas de produção e qualidade das uvas devido à ferrugem da videira são elevadas. A doença causa queda de folhas, tamanho e cor desigual de bag

2. Fertility of buds and pruning recommendation of different grapevine varieties grown in altitude regions of Santa Catarina State, Brazil
ABSTRACT Low bud fertility index is frequently observed in different grapevine varieties grown in high altitude of Santa Catarina Sate; in many cases less than one cluster per bud is observed. The objective of this study was to assess bud fertility of twenty six Vitis vinifera L. varieties and from this information, to recommend the method of pruning more s

3. Row orientation effects on Syrah grapevine performance during winter growing season
ABSTRACT The sunlight and heating effects on leaves and grapes are directly influenced by row orientation in vineyards. Row orientation studies have not been addressed under double pruning management, a technique used to transfer the wine grape harvest from wet summer to dry winter season in Brazilian Southeast. Effects of grapevine row orientation (north/so

4. Maturation and Maceration Effects on Tropical Red Wines Assessed by Chromatography and Analysis of Variance - Principal Component Analysis
Effects of grape maturity, maceration length during winemaking and interaction of both of them on physicochemical parameters, phenolic and volatile composition were investigated in tropical Syrah wines with the aim of finding the best conditions to produce wines that are rich in phenols and positive aroma active compounds. A headspace solid phase micro extra

6. Movimento de nitrato e potássio em solo arenoso cultivado com videira (Vitis vinifera L.) fertirrigada no Semiárido
Resumo A prática da fertirrigação pode aumentar a eficiência de aplicação de fertilizantes e facilitar o manejo nutricional de uma cultura agrícola. Assim, os movimentos de nitrato e de potássio em solo de textura franco arenosa foram avaliados em função da dose de fertilizantes, durante três ciclos de produção da videira de vinho cv. Syrah sob

9. Plant parameters and must composition of ‘Syrah’ grapevine cultivated under sequential summer and winter growing seasons
ABSTRACT Plant variables and must physicochemical properties were evaluated for the grapevine ‘Syrah’ cultivated in sequential growing seasons (summer and winter) from 2011 to 2015. The vines were trellised in vertical shoot position, grafted on Paulsen 1103, with approximate density of 5,800 plants∙ha−1. They were grown under plastic overhead cover.

11. Rootstock on vine performance and wine quality of ‘Syrah’ under double pruning management
ABSTRACT In the Brazilian Southeast, the production of high quality wines is attained by a new management approach called double pruning. This management changes the harvesting of wine grape (Vitis vinifera L.) from wet summer to dry winter through a two pruning procedures carried out during the year. The first pruning is done during the winter to induce a v

12. Canopy management effects on ‘Syrah’ grapevines under tropical semi-arid conditions
ABSTRACT The aim of this study was to evaluate the effects of shoot topping and leaf removal practices on vegetative vigor, yield and physicochemical characteristics of the 'Syrah' grape in the semi-arid tropical climate conditions of the São Francisco River Valley in the northeast of Brazil. The experiment was conducted over five growing cycles from 2010 t
