TerraClim, an online spatial decision support system for the wine industry

Abstract

Climate projections for the future suggest favourable conditions for some wine producing regions, but challenging conditions for others. For instance, temperature increases are likely to shift grapevine phenology, ripening and harvest dates, and potentially affect grape quality and yield. The commercial value of accurate and up-to-date climate emerged from feedback received in response to a series of demonstrations to the wine and fruit industries. TerraClim combines high resolution terrain data with weather station data (sourced from several data providers) to model climatic conditions within an orchard or vineyard. The TerraClim climate database allows for dynamic mapping, statistical interrogation, data mining, machine learning and climate change analyses over time and space. The TerraClim initiative has a strong research and development drive that involves continuously updating and extending the climate and terrain databases, automated data collection, interpolation protocol development, as well as the extension of existing logger and weather station networks. The developed technology is novel and scalable to other regions. As proof of concept, the TerraClim webapp (www.terraclim.co.za) presents high temporal and spatial resolution maps of climatic and geographic datasets as a series of dynamic near-real time map layers. The webapp includes an interactive vineyard profiling tool, query functionality and crop/cultivar suitability analysis. TerraClim allows users to obtain pertinent information about climate, terrain and soils to aid long- and short-term agricultural decision-making.

Investigation on the potentiality of a biostimulant by Fabaceae tissues and rich in triacontanol to enhance grapevine resilience under drought stress

The primary objective of this research was to investigate the potential benefits of a Fabaceae-based product rich in triacontanol (a long-chain alcohol) applied to Vitis vinifera cv. Merlot, on key physiological and productive parameters of grapevines under controlled water stress conditions.

Juvenile-to-adult vegetative phase transition in grapevine 

The sequential activity of miR156 and miR172 controls the juvenile to adult phase transition in many plant species, where miR156 abundance decreases while miR172 increases along plant development. Very little is known about phase transition in horticultural woody species, which show substantially long vegetative phases. In grapevine, phase transition seems to be dissociated, displaying a first transition from juvenile to adult vegetative state in the first year, coincident with tendril differentiation and a subsequent induction of inflorescences in place of some of tendrils in later years under flowering inductive environmental conditions. Since grapevine is a highly heterozygous species, the generation of genetically homogeneous material for replicated transcriptomic analyses from seed-derived plants was a main challenge.

Phenolic composition profile of cv. Tempranillo wines obtained from severe shoot pruning vines under semiarid conditions

One of the limitations of vineyards in warm areas is the loss of wine quality due to higher temperatures during the grape ripening period. In order to adapt the vineyards to these new climatic conditions, a possible solution is to delay the ripening process of the grapes towards periods with milder temperatures, by means of management practices and thus improve the quality of the fruit and the wine produced. The technique of severe shoot pruning (SSP) has proven useful in achieving this objective.

Tomatoes and Grapes: berry fruits with a (bright) biotech future?

Tomatoes and Grapes are berries that are genetically related and therefore at least partially their developmental pathways leading to a fleshy fruit should share some of the components. In a sense knowledge obtained from the model plant tomato could be useful for grape and conversely the more amenable tomato can be used to test some hypothesis that would be difficult to obtain in grape. Research in my lab and other labs have led to a better understanding of the molecular genetics mechanisms underlying fruit development and ripening in tomato and more specifically those related to metabolite accumulation that may lead to changes in fruit nutritional and flavor composition. This research has involved the use of genetic variability in natural population, but also biparental population and genetically engineered lines that are easy to develop in tomato tomato but not in grape. NGTs also can be easily implemented in tomato to not only speed up the gene-to-trait but also develop new tomato varieties.

The landscape in the development of vineyard regions: an application to the ACO Dão and ACO Bairrada (Central Portugal)
