Varieties and rootstocks: an important mean for adaptation to terroir

Abstract

A large genetic diversity exists among V. vinifera varieties, but also among cultivated rootstocks. This diversity is important to adapt plant material to different environmental conditions and contributes to the expression of terroir. Plasticity, i.e. the level of modification of the expression of individual characteristics of a genotype in different environments, is also important for adaptation. The most important physiological parameters which contribute to this adaptation are briefly reviewed. For varieties, phenology, drought responses and ripening processes are crucial. For rootstocks, variability in nutrients and water uptake, as well as their effects on whole plant development is important. A better description and understanding of the genetic variability and plasticity for these traits is highly required in order to improve the adaptation of the plant material to the current growth conditions. It will also help to develop strategies in order to respond to the ongoing climate change.

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.

Wine tourism as a catalyst for sustainable competitive advantage: unraveling the role of winery image and reputation

This study examines the impact of wine tourism development on the sustainable competitive advantage of Spanish wineries, while also exploring the mediating roles of winery image and winery reputation in this relationship.

Effect of spray with autochthonous Trichoderma strains and its secondary metabolites on the quality of Tempranillo grape

Trichoderma is one of the most widely used fungal biocontrol agents on vineyards due to its multiple benefits on this crop, such as its fungicidal and growth promoting capacity. In this work, we have analyzed the effect on the concentration of nutrients in grapevine leaves and on the quality of the grape must after spraying an autochthonous strain of Trichoderma harzianum and one of the main secondary metabolites produced by this genus, 6-pentyl-α-pyrone (6PP).

Eugenol:  a new marker of hybrid vines? The case study of Baco Blanc in Armagnac

Nowadays, winemaking is dealing with great challenges, notably climate change, disease resistance and low pesticide inputs, desire for more sustainable agricultural productions and permanent changing of consumer preference. Trying to propose practice improvements, scientists are exploring vine hybridization a paradoxically old but still actual way to take up such challenges

Non-targeted analysis of C13-norisoprenoid aroma precursors in Riesling

Significant wine aroma can be formed from non-volatile precursors that are linked to sugars, including but not limited to grape-derived monoterpene and C13-norisoprenoid glycosides.
