VitiNord 2022 – Posters session


The poster presents a detailed analysis of the 30 most important cultivars used in the growing in Denmark over the last 15 years. How successful are they in getting ripe and what is the quality of the fruit? Both the developmental time needed from flowering to harvest as well as the time of maturation is analyzed. The main wine styles produced from each of the cultivars is also included.


The poster presents the new breeding project FastGrapes initiated in 2020 as a cooperation between Toldam-Andersen and the breeder O. Trapp at JKI, Geilveilerhof in Germany. Test fields with the first 25 selections have been established by growers in Denmark (6 locations), Sweden (2 locations) and Germany (2 locations). The profile of resistance loci in the material is presented together with the plan for the testing phases and future release of cultivars.

There is a general agreement among scientists and grape specialists that proper canopy (CM) and fruit zone management (FZM) are essential practices to obtain good quality grapes. Fruit zone management involves leaf removal around the clusters. The ultimate objective of both CM and FZM is to improve grape aroma, flavour and pigment profiles, favour earlier maturity and reduce diseases. Practices of fruit zone management were evaluated for their effect on disease management during summer 2019 and 2020.  The practices were leafing around the cluster zone on: 1) one side of the row at nouaison; 2) two sides of the row at nouaison; 3) one side of the row at veraison; 4) two sides of the row at veraison; 5) no leafing (control). Downy mildew, powdery mildew, and botrytis bunch rot were assessed weekly on leaves and at harvest on clusters. Regardless of the treatment, the effect of fruit zone management practices was small but significant. For both timing of leaf removal, nouaison and veraison, lower disease severity was observed when leaves were removed on both sides of rows. Overall, lowers disease severity was observed when leaves were removed at nouaison as compare with veraison. The difference in disease severity may be explained by lower humidity and better fungicide penetration in the canopy in sub-plots where leaves around the clusters were removed on both sides of rows at veraison. The removal of leaves from the fruiting area promotes the penetration of fungicides during a localized treatment but also of general coverage.

Impact of Spring Frost on Frontenac and Marquette Grapes in Northern New York

Timothy E. MARTINSON and Chrislyn PARTICKA. Section of Horticulture, Cornell Agritech, Cornell University, Geneva, NY 14456

The winter of 2014-2015 was relatively cold, but vines in our training trials at Clayton NY came through the winter with little winter injury.  However, a frost event occurred on Memorial Day weekend, when shoots were out 2-6 inches, and killed over 90% of the primary shoots. We documented the vines’ recovery and how the frost impacted both phenology and fruit composition.  Secondary shoots emerged following the frost event, and delayed phenology by about 3 weeks.  There were two crops: an early crop on 10% of the shoots and a larger, delayed second crop from secondary shoots emerging after the frost.  Fruit composition varied, with 2nd crop having 1 degree lower brix than the 1st crop and 4 g higher titratable acidity (21.2 g/l vs 17.4 g/l) at harvest. This training trial was funded by the Northern Grapes Project, USDA SCRI Project 2011-51181-30850

Vintners are always testing new ways of improving their products. Sometimes, these efforts are focused on proving different ways of producing wine, changes in the management of the vineyards, or the way grapes are harvested. However, the use of varieties typically grown in areas with very different climatic characteristics is not that common. This is the case of the cultivar Gewurztraminer, a German variety cultivated in one of Spain’s hottest and driest regions, Extremadura. This variety shows an optimal ripening temperature ranging from 15ºC to 17ºC, a very different situation from that of the Mediterranean climate in which the average mean temperature during the ripening period is 22.4ºC. In this latitude, the production is low with only 800g per plant. In addition, to ensure some climatic conditions similar to those in higher latitudes, the harvest is done during the night and the grapes are stored in a chamber at 2ºC for 24 hours. Pressing is done with the grapes at 6ºC. Under these conditions, the Gewurztraminer cultivar provides grapes that produce a wine with a lemon straw yellow color. Clean and very bright. The nose is surprisingly fragrant and powerful, with floral aromas (roses), exotic fruit (litchis), and citrus. On the palate, it is fresh and silky. Very aromatic with sweet sensations, with a long and persistent finish. The winery that grows this variety only produces 1200 bottles per year under organic management in vineyards planted in 2004. Although this is not the best product of it, this wine is in high demand and exemplifies the capacity of the world of wine to reinvent, test, and look for different possibilities that, in the end, enrich the options offered to wine lovers.

Viticultural practices and landscape composition are strong influencing factors for ecosystem services and biodiversity in vineyards. Phytoseiid mites on vines in this context are important natural enemies for the pest control service against pest mites. In this study, we examined the effect of farming type, inter-row management and landscape composition on phytoseiid mites in 156 vineyards across five European wine-growing regions. Our results showed that phytoseiid mite communities were mainly dominated by one or two species in the investigated vineyards. According to the wine-growing regions, the farming type was a major factor for phytoseiid mite densities whereby integrated and conventional farming showed the highest densities compared to organic farming. Furthermore, phytoseiid mite densities benefited from spontaneous vegetation cover in the vineyard inter-row compared to seeded cover crops and from an increasing proportion of vineyards in the landscape. The effect through the farming type were mostly linked to the beneficial impact of a lower pesticide use in integrated and conventional vineyards. The positive effect of spontaneous vegetation cover could be related to a better supply of pollen as food resource, which depends on plant species richness, compared to seeded cover crops. Our research showed accordingly, that a reduced use of pesticides and vegetation cover in the inter-row are important factors to promote phytoseiid mites as natural enemies in European viticulture. Moreover, a factor which should be considered for stable phytoseiid mite population is the proportion of viticultural area in the landscape.

Three Years of Frontenac and Marquette Training Systems Trials in Northern NY

Timothy E. MARTINSON and Chrislyn PARTICKA. Section of Horticulture, Cornell Agritech, Cornell University, Geneva, NY 14456

Training trials From 2012 to 2016 compared performance of three training systems: 1) midwire cane-pruned Vertical Shoot Positioning (VSP); 2) High cordon; and 3) Cane-pruned Umbrella Kniffin.   High cordon (or Top Wire Cordon) had the highest yield, followed by Umbrella Kniffen and VSP. Despite yields in Marquette that were 2x higher than VSP, fruit composition was largely equivalent among the training systems. For both Marquette and Frontenac, sunlight-exposed clusters had higher soluble solids (brix) and lower titratable acidity than shaded clusters from the same  vines.  Having well-exposed clusters is the key to minimizing acidity at harvest.

The poster is an update of a long tradition at the VitiNord conferences of presenting the status of the development in our country. The development in number of commercial producers, the area, cultivars used and amount of produced wine.
