Remote sensing applications in viticulture: recent advances and new opportunities

Abstract

Remote sensing applications in viticulture have been a research theme now for nearly two decades, becoming a valuable tool for vineyard management. Metrics produced using remotely sensed images of vineyards have yielded relationships with grape quality and yield that can help optimise vineyard performance. While valuable at the scale of precision viticulture, opportunities for spatial applications at the terroir scale are yet to be fully explored. The spatial scale of terroir analysis is different to precision viticulture and requires adaptation and new models of analysis.

With the rising availability of high spatial and temporal resolution datasets, increasing computing power and advances in image processing software, the opportunities for vineyard interrogation through spatial analysis are increasing. Remote sensing and image analysis techniques that are becoming more accessible include: object based image analysis, spatiotemporal analysis, hyperspectral analysis and topoclimatology. Each of these techniques has potential for development within a viticulture and terroir context. This paper investigates the use of these techniques in a spatial science framework at various scales and identifies potential opportunities for their application in a terroir context, particularly in terms of terroir zoning.

Prospects of thermal imaging as a non-invasive tool to assess water status for irrigation scheduling in commercial vineyards

Aim: Irrigated viticulture is expanding worldwide mainly as a short-term adaptation strategy to climate change. Plant-based methods are increasingly being used for irrigation scheduling in commercial vineyards. Canopy temperature (TC) has long been recognized as an indicator of plant water status. TC, but also the thermal stress indices, e.g. crop water stress index (CWSI) and stomatal

Using combinations of recombinant pectinases to elucidate the deconstruction of the polysaccharide‐rich grape cell wall during winemaking

The effectiveness of enzyme-mediated maceration processes in red winemaking relies on a clear picture of the target (berry cell wall structure) to achieve the optimum combination of specific enzymes to be used. However, we lack the information on both essential factors of the reaction (i.e. specific activities in commercial enzyme preparation and the cell wall structure of berry tissue). In this study, the different combinations of pure recombinant enzymes and the recently validated high throughput cell wall profiling tools were applied to extend our knowledge on the grape berry cell wall polymeric deconstruction during the winemaking following a combinatorial enzyme treatment design.
