Project description
One of the problems facing most viticultural studies is that it is difficult to explain the link between an action or impact (biotic or abiotic) in the vineyard and the associated impact on the grapes and wine.

It is now possible to implement molecular biology tools in the study of grapevines in vineyard settings. The basic information generated regarding the growth and development of the grapevine with these tools is extremely valuable to explain why a specific response is obtained, specifically when the study is conducted within the framework of a broader viticultural study.

The objectives of the study are to perform molecular and metabolite profiling of grapevines in vineyard settings to understand how environmental factors impact vine biology and influence quality traits. The proposed work is planned in collaboration with and in support of existing viticultural studies and will focus on the effect of light and temperature on grape development or composition.

Understanding how a grapevine adapts on a molecular level to its physical environment (due to viticultural management practices or abiotic, biotic stresses) is a prerequisite if predictive measures of plant status and/or berry quality are to become part of the vineyard management system. The ability to analyse the grapevine molecular ‘phenotype’ in a vineyard setting will assist researchers in quantifying the impact of viticultural practices, leading to informed decisions regarding these practices and their improvement. This will significantly advance our understanding of the processes involved, predisposing factors as well as possible ways to protect grapes against adverse climatic conditions. Ultimately, this knowledge could lead to predictive markers; instruments to monitor ripening and stress impact factors during this period, and improved management practices.
