Cultivation of grapes Chardonnay in soils with management practices biodynamic and conventional

Abstract

Context and purpose of the study – The cultivation of grapes, can be accomplished with the use of different systems and practices of agricultural management, the choice of the system to be followed in the vineyard, depends on the conditions of available resources, these being: natural, economic, social, cultural and territorial. As well, it is relevant to know the characteristics of the soil of the vineyard. In the last decade, has been recurrent use of agricultural practices which date back to milinares traditions, with the aim of promoting a recovery of soil and lead the management of cultivation with less damage to the ecosystem. The study here, aimed to quantify the environmental impacts caused in the use of nutrients in conventional tillage and of grapes in the biodynamic agricultural properties in the state of Rio Grande do Sul- Brazil.

Material and methods – Soil samples were collected from vineyards with a conventional and biodynamic management of Chardonnay vine cultivation system. The soil samples were collected in the vines line of 0-20, and 08 samples were randomly sampled in each hectare of the vineyard. Then, the chemical analysis was performed using the Rolas methodology and soil quality analysis to identify fertility and humification to measure the environmental impact caused in the soil.

Results – The results showed that the use of the soil analysis is an important tool for monitoring the vineyard, mainly in relation to the climatic conditions of the region winery in study. The analysis showed that the soil has the capacity to retain nutrients, capillarity, thickness, heat emission, exposure to the sun, physical properties and, especially, control of water supply, a determinant factor for the good quality of vinífera. The study concluded that the biodynamic contribute to fertility and the reduction of soil acidity. In addition, identified that the production of inputs for the treatment of planting, the agricultural unit, allows a better interaction with the environment and the use of raw materials and waste.

L’essor des produits “No-Low” : nouveaux défis pour l’étiquetage et la réglementation

In recent years, “no-low” products seem to become a new worldwide trend. It appears to be a possible answer to the well-known context of climate change, the decline in wine consumption, and the wellness/health trend (“free from” claims, vegan, and so on…) That consumers are looking for. The aim of this study is to provide an overview of the “no-low” products sold in the french market (but not only french products), focusing on the labelling, packaging, and sales presentation of these products.

Impact of press fractioning on Pinot noir and Pinot meunier grape juice and wine compositions and colour

The separation of different grape juice press fractions is an important step in the production of sparkling base wines. A complete press cycle for this style of wine is a series of pressure increases (squeezes) resulting in variations in juice composition during the press cycle. After alcoholic fermentation, wines obtained from grape juices also exhibit strong differences for numerous characteristics. Nevertheless, there is no statistical study of the impact of the press cycle on grape juices and wine colour/composition. So, the aim of this study (vintage 2018) was to investigate the changes in composition and colour parameters of Pinot noir and Pinot meunier grapes juices, as well as their corresponding wines, during the pressing cycle.

Optimized protocol for high-quality RNA extraction from grape tissues using sorbitol pre-wash

Obtaining high-quality RNA from grape tissues, including berry pulp, berry skins, stems, rachis, or roots, is challenging due to their composition, which includes polysaccharides, phenolic compounds, sugars, and organic acids that can negatively affect RNA extraction. For instance, polyphenols and other secondary metabolites can bind to RNA, making it difficult to extract a pure sample. Additionally, RNA can co-precipitate with polysaccharides, leading to lower extraction yield. Also, sugars and organic acids can interfere with the pH and ionic properties of the extraction buffer. To address these challenges, we optimized a protocol for RNA isolation from grape tissues.

Lamp – a modern tool for the detection of fungal infections in the vineyard

AIM: Loop-mediated isothermal amplification (LAMP) [1] is a modern technology for fast and sensitive amplification of specific DNA sequences under isothermal conditions. Its simple handling and no need for dedicated equipment together with an evaluation of the amplification event by in-tube detection make this method advantageous and economically affordable for on-site investigations in the industry.
