Analyse de la perception du terroir et de sa valorisation par les viticulteurs de l’Anjou


An integrated terroir characterization is currently realized in the French northern vineyard: “Anjou”. The concept of Basic Terroir Unit (B.T.U.) and its associated ground model “Rock, Alteration, Alterite” are used in this characterization. This work is coupled to a viticultural survey, based on parcels. These two approaches allow an analysis of the degree of perception of terroir and its valorization by vine growers. This analysis is realized at two scales: the ground model “Rock, Alteration, Alterite” applied in the whole study area and the B. T. U. for the both main geological systems: the metagrauwacke of the brioverian period and the green to grey sandstone schist of the ordovician-devonian period.
At the ground model scale, the vine growers have well differentiated the three environments by mesoclimatic (temperature of air, risk of frost), pedoclimatic (temperature and humidity of soil) and pedologic criteria. They have perceived also influences of the environment type on the behavior of the vine and integrated them in their viticultural and oenological practices. The analysis at B.T.U. scale, confirms the pertinence of the ground model “Rock, Alteration, Alterite” on the perception of pedoclimatic and pedologic characteristics and an important influence of the geological system on the mesoclimate of the parcel and on the vine behavior.

Genetic identification of 200-year-old Serbian grapevine herbarium

Botanist Andreas Raphael Wolny collected a grapevine herbarium from 1812-1824 in Sremski Karlovci (wine region of Vojvodina, Serbia), which represents local cultivated grapevine diversity before the introduction of grape phylloxera in the region. The herbarium comprises over 100 samples organized into two subcollections based on berry colour (red and white varieties), totaling 47 different grape varieties. The objective of this study was to investigate the historical varietal assortment of Balkan and Pannonian winegrowing areas with long viticulture traditions.

Copper reduction strategy for sangiovese in organic viticulture

Organic viticulture requires copper based treatments for bunch protection even though an intensive employment is no longer admitted because of its low leaching and phytotoxicity in the soil. UE Reg. 1981/2018 set copper employment to 4 kg/ha for year or 28 during 7 years with an absolute level allowed of 6 Kg/ha although those limits were decreased frequently.
