1. El Niño-Southern Oscillation impacts on grape yields in Santana do Livramento, Brazil: understanding and early warning of crop failure conditions
ABSTRACT El Niño-Southern Oscillation (ENSO) is an important source of year–to–year fluctuations in the whole global climate system and in the southern Brazilian climate. El Niño events affect this region, imposing unfavorable weather conditions (rainy/humid/overcast) during critical grapevine phenological stages, compromising yields in the current and

2. Rooting potential of grapevine rootstocks cuttings
ABSTRACT The objective of this work was to evaluate the rooting potential and propagation of seventeen grapevinevine rootstocks. The experiment was carried out in the municipality of Canoinhas - Santa Catarina, in 2018 and 2019. Woody canes from the grapevine rootstocks 99R, 110R, 420 A Mgt, 101-14 Mgt, IAC 766, IAC 313, IAC 572, Courdec 3309, Freedom, Grave

3. Difference and characteristics of anthocyanin from Cabernet Sauvignon and Merlot cultivated at five regions in Xinjiang
Abstract Anthocyanin plays an important role in wine color and quality. The anthocyanin concentration in grapes depends on the variety and is influenced by environmental factors, such as temperature, sunlight, soil, and grapevine practice. In this study, the anthocyanin profiles of two varieties, namely Cabernet Sauvignon and Merlot, from five regions (11 pl

4. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

5. Determination of the grapevine virome by high-throughput sequencing and grapevine viruses detection in Serra Gaúcha, Brazil
ABSTRACT Among grapevine (Vitis spp.) pathogens, viruses stand out, considering that this fruit plant is broadly susceptible to them and that they cause several diseases, reducing quality and yield of grape production. However, detecting and identifying viral infections in grapevines can be challenging. The objectives of this study were to detect grapevine v

6. 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

7. Rootstock-scion interaction:6. Phenology, chilling and heat requirements of Cabernet Sauvignon grapevine
Resumo A fenologia da videira depende de vários fatores, como genética, características do solo, condições climáticas, pragas e doenças, e práticas culturais do vinhedo. Dentre estas, o porta-enxerto pode ter influência no comportamento da copa. Devido a isso, este experimento foi conduzido por dois anos para determinar o efeito do porta-enxerto na

8. High genetic differentiation of grapevine rootstock varieties determined by molecular markers and artificial neural networks
ABSTRACT. The genetic differentiation of grapevine rootstock varieties was inferred by the Artificial Neural Network approach based on the Self-Organizing Map algorithm. A combination of RAPD and SSR molecular markers, yielding polymorphic informative loci, was used to determine the genetic characterization among the rootstock varieties 420-A, Schwarzmann, I

9. TEMPORAL VARIATION AND SPATIAL DISTRIBUTION OF RELATIVE INDICES OF LEAF CHLOROPHYLL IN GRAPEVINE cv. CHARDONNAY
ABSTRACT Variation in the spatial distribution of leaf chlorophyll content associated with the progression of the phenological cycle of crops may occur in cultivated areas as a result of the variability of environmental conditions and of the intrinsic properties of the plants. The objective of the present study was to model the trend in variation and assess

11. DELIMITATION OF HOMOGENEOUS ZONES IN VINEYARDS USING GEOSTATISTICS AND MULTIVARIATE ANALYSIS OF DIFFERENT VEGETATION INDICES
ABSTRACT Vegetation indices (VIs) are quantitative measures used to describe the distribution and spatial variability of the vegetation cover of natural or cultivated areas. The aim of this study was to delimit homogeneous zones (HZs) of different VIs using geostatistics and multivariate analysis in order to identify vegetation patterns in Cabernet Franc and
