Monitoring early rooting behavior of grapevine rootstocks: a 2D-imaging approach

Abstract

The plasticity of grapevines in response to diverse growing conditions is influenced, among other factors, by the extent to which the roots explore the soil and the ability to accumulate and retrieve water and nutrients.

Newly planted grapevines, in particular, face challenges due to limited resources. The young plant’s ability for a fast and intensive penetration of the soil is vital in periods of water scarcity. The selection of an appropriate, site-specific rootstock significantly impacts both, the quality of the fruit produced and the economic success of the wine estate. This underscores the importance of providing guidance and recommendations to winegrowers, enabling them to make informed decisions about the selection of suitable planting materials. Despite its critical significance, there is very limited information available on the early rooting behavior of commercial rootstocks. Observing below-ground growth poses challenges, but the use of rhizoboxes has proven effective in investigating root-related issues across different species.

Therefore, we established a semi-automated platform using RGB imaging to monitor the root development of three commercial grapevine rootstocks and characterize root architecture parameters including maximal rooting depth and the area colonized by roots. The image processing method enables a rapid batch analysis, yielding reliable data that is highly comparable to the manually assessed reference dataset. This approach serves as a valuable framework for future evaluation of the assertiveness of commercial grapevine rootstocks under challenging planting conditions.

Grape seed powder as an alternative to bentonite for wine fining

PR proteins can cause haze in wines, and the risk is to keep the wine unsold. Generally, in winemaking bentonite solves this problem by removing proteins, but it is not a renewable resource, has poor settling, which means difficulty in filtering after use and a considerable loss of wine, it is not a specific adsorbent and may reduce aromas and flavor compounds

Variabilité spatiale du gel printanier dans le vignoble champenois : application au zonage climatique

In the Champagne vineyards, spring frosts are the cause of significant variations in the volume of the harvest which are very penalizing for the trade. This variability is reflected both in time (years without frost alternating with years with severe frosts) and in space. Certain sectors of the vineyard are in fact statistically more susceptible to frost than others, but each year no municipality can consider itself immune to this climatic accident. The objective of the study is precisely to analyze the spatial distribution of frost and to determine its main mechanisms, linked to the topography of the hillsides, their orientation but also to regional meteorological variables.
