Vineyard’s ozone application to induce secondary metabolites accumulation in grapes and wine

Abstract

In viticulture sector to find new tools for pest management has become an urgent necessity. Hence, grapevines cultivation has high production rate demand and to meet the intensive market request, a massive use of pesticides is often required. In addition to the environmental problems associated with large use of chemicals, there is an increasing number of consumers which are asking for safer, healthier and residue free foods and beverages. Recently, the use of ozone has been proposed as a possible alternative to traditional chemicals. However, studies on ozone application in the vineyard are very few especially considering its effect on grapes and wine quality and composition. In plant tissue ozone induce an oxidative stress which can triggers antioxidant response, and, therefore, it may enhance the production of antioxidant and stress-related secondary metabolites. As such, ozone can be considered an abiotic elicitor. In this study, canopies of Vitis vinifera (cv Sangiovese) plants have been sprayed with ozonated water throughout the vegetative growth and its effect on phenolic, antioxidant and aromatic compounds of grapes and wine have been assessed. In grapes, ozonated water induced a significant increase of antioxidant activity and total polyphenol content. Remarkably, changes in phenolic and aromatic profile in the resulting wine have also been observed. Specifically, Kampferol and Quercitin glucosides increased after ozone exposition as well as volatiles derived from the LOX-HPL pathway. These changes suggest that the oxidative stress induced leads to antioxidant metabolic response in grapes and therefore affects grapes and wine quality and composition.

Application of GiESCO “bio-metaethics” charter in practice: the “direct” involvement of vine grower, winemaker, society

On the basis of a direct agreement between the GiESCO and the vine grower, the winemaker and the consumers (individual; company; public or private organizations), the communication on the content of the charter can be done as follows:
• Commitment to respect the basic rules of the GiESCO “BIO – MetaEthics” charter.
1/ Put Mankind in the depth of all concerns in a universal context: (grower, consumer, citizen, work valuing, education, security)
2/ Insure minimum impact on environment by optimizing cultivation technics: (maximum of natural biodegradable products, friendly practices, short channels, renewable energies, terroir sustainability)

Manipulating grapevine bud fruitfulness

Bud fruitfulness is a key component of reproductive performance of grapevine. It plays a significant role in annual yield variation of vineyards as it is a prerequisite of crop production in the following season. Various exogenous and endogenous factors influencing the development of inflorescence primordia (IP) have been studied. However, the research on molecular genetic control of bud fruitfulness, especially how it interacts with environmental factors is still lacking. This study aims to investigate the molecular mechanism of effects of temperature and light on grapevine bud fruitfulness during initiation and differentiation of IP.

WHAT’S FUTURE FOR SANTORINI’S VITICULTURE IN THE CONTEXT OF CLIMATE CHANGE

The own-rooted vineyard of Santorini is a unique case of vineyard worldwide that is been cultivated for thousands of years. On the island’s volcanic soil, the vines are still cultivated with traditional techniques, which are adapted to the specific and extreme weather conditions that prevail on it. While climate change is a reality in the Mediterranean region, will Santorini vineyard endure its impact? The study of the traditional training systems, techniques and vine density, as well as the application of sustainable solutions (cover crops and use of kaolin etc.) revealed sustainable methods for the adaptation of the local viticulture to new climatic phenomena that tend to be more and more frequent in the region due to climate change.

Vineyard management strategies adopted to mitigate the impacts of climate change affect the evolution of phenolics and color during bottle aging of Aglianico wines

In recent years several strategies have been proposed to cope with the effect of climate change on grape berry quality but only a few studies have dealt with the influence of management practices implemented in the field (e.g. irrigation,summer pruning, etc.), on the evolution of wines over time.
