Predicting grapevine starch levels using infrared spectroscopy

Abstract

Proof of concept for a simple, fast and accurate spectroscopy method was proposed for determining starch content of grapevine using Near-Infrared (NIR) and Mid-Infra Red (MIR) spectroscopy. The potential of this approach was assessed by comparison with traditional wet chemistry determination of starch. Cane samples from five different vineyards from Southern Tasmania were used in this study. Strong correlations were obtained for NIR (R2 = 0.89 and RMSECV = 0.66) and MIR (R2 = 0.72 and RMSECV = 1.11).

Risk of late frost events in viticulture – temperature trends, phenological observations and spatial analysis based on digital terrain models in Franconia/Germany

In the course of global warming a general decrease of frost days per year and in spring can be stated. However, in viticulture this matter of fact doesn´t lead to a reduction of the risk of damages to grapevines by late spring frost events.

Estimating leaf area and leaf area index in VSP trained grapevines under different management systems (Vitis vinifera L. cv. Riesling)

The aim of this study was to validate and implement different non-destructive methods of leaf area and leaf area index (LAI) determination in VSP trained grapevines (Vitis vinifera L. cv. Riesling) in a field trial comparing different management systems (i.e. integrated (GAP) and two different organic (European Union Regulation 834/07) management systems).

Classification for timing of flowering and veraison of a wide range of Vitis vinifera cultivars with the “GFV” model

In viticulture, the timing of phenology is critical to optimize grape quality potential particularly so in cool climates. Flowering and veraison are key phenological stages for grapevines.
