Grapes are considered one of the world leading fruit crops. They can be grown in various climatic conditions and are highly economically important. Excessive management practices, such as soil preparation, abuse of nitrogen fertilizers and tractors traffic in the vineyard, may reduce the soil fertility and biodiversity, besides altering the balance...
In viticulture, choosing the most suitable rootstock for a specific scion cultivar is an efficient and cost-effective way to increase yield and enhance the physicochemical characteristics of the fruit. The objective of this study was to evaluate the agronomic performance of the ‘BRS Tainá’ grapevine on different rootstocks under the conditions of t...
A podridão da uva madura tende a surpreender os produtores devido ao aparecimento dos sintomas em período próximo à colheita ou na pós-colheita, quando as alternativas de manejo da doença são mais restritas.
O excelente desempenho dos vinhedos do Semiárido nordestino a partir da década de 1980 firmou o Vale do São Francisco como um grande produtor de uvas e vinhos finos em condições irrigadas. Com isso, várias práticas de manejo são realizadas para superar essas adversidades de natureza biótica e abiótica, entre elas, o uso de extratos de algas. O obje...
The seedless table grape ‘BRS Melodia’ stands out for its pink color and the special flavor of red berries, which make for commercial classification as gourmet type grapes. Cultivation of this new table grape cultivar is expanding in the São Francisco Valley, in the Brazilian Northeast region. The aim of this study was to determine the effect of th...

The influence of the mineral and hormonal composition of the growing medium on the development of explants of fruit crops and grapes in vitro has been studied. As a result of the studies, it has been found that phytohormones have a positive effect on the regeneration of explants in vitro. When using standard compositions of nutrient media not addin...
Developing new table grape cultivars that exhibit high yield and superior fruit quality is imperative to meet the escalating demands of the consumer market in the Lower-Middle S˜ao Francisco River Valley. The primary objective of Embrapa Semi´arido’s Active Germplasm Banks (AGB) for grapes is the conservation of Vitis sp. germplasm under semi-arid ...
Winegrapes are a valuable ($70 billion) commodity, but climate change is predicted to reduce grape yield and quality by exacerbating water and heat stress. Developing stress-resistant varieties would mitigate these impacts, but the trait values to target can be obscured by complex relationships between traits and plant performance. Stomatal traits ...
The effect of both potassium and organic fertilisation on grape yield and must composition originating from wine grapevines cultivated in the São Francisco river basin, in the semi-arid region of Northeastern Brazil, is not well known. Since soils from that region usually have low organic matter content, we hypothesise that soil application of orga...
Viticulture is the main agricultural production in the São Francisco Valley, Brazil; however, farm soil management systems require large volumes of fertilizer that could contribute to climate change. Therefore, using plant growth-promoting rhizobacteria (PGPR) has been reported to reduce or replace plant input. This study aimed to evaluate the bact...
