Selecting green cover species in the under-trellis zone of Lower Austrian vineyards


The under-trellis zone of vineyards is a sensitive area through which vines cover a significant portion of their nutrient and water needs. Mechanical and chemical methods are applied to suppress competing and tall-growing weeds to ensure optimal vine growth conditions. In addition to higher operating costs and depending on the soil conditions, these practices might lead to a long-term reduction in soil fertility and biodiversity. The presented study aims to analyse the suitability and interspecies competition of a selected green cover mixture of five local herbaceous species as potential green cover mixture in the under-trellis area of Lower Austrian vineyards. A combined mixture of five herbs (Arenaria serpyllifolia, Thymus serpyllum, Potentilla argentea, Sedum acre, Sedum album) were planted (0,0625 m2 per plant) in the under-trellis area of two Lower Austrian vineyards in Rohrendorf (loess) and Zöbing (loess-sand). The research design involved a split-plot design with four plots, each plot with five vines. After 110 days plant performance and ground coverage were assessed on cover plant basis. The overall results showed promising growth rates of four out of five green cover species within the first year. The growth rates of T. serpyllum, P. argentea, S. acre, S. album ranged between 10,42-23,44% on both sites. A. serpyllifolia showed with 0,00-1,56% a reduced growth rate. Comparing the two sites, plant performance was higher in Rohrendorf with dominating loess, compared to Zöbing with increased sand content, potentially due to increased water and nutrient availability. Similarly, the results of the ground coverage showed differences with coverage rates of 12,15% in Rohrendorf and 3,68% in the Zöbing vineyards. In summary the study suggests a suitable site adaption of four analyzed green cover species in the first season. Further long-term experiments involving seeding techniques, grapevine interaction, soil analyses and additional green cover species are recommended.

Applicability of grape native yeasts to enhance regional wine typicity

The universalization in wine production has been restricting the imprint of terroir in regional wines, resulting in loss of typicity. Microbes are the main driving force in wine production, conducting fermentation and originating a myriad of metabolites that underly wine aroma. Grape berries harbor an ecological niche composed of filamentous fungi, yeasts and bacteria, which are influenced by the ripening stage, cultivar and region. The research project GrapeMicrobiota gathers a consortium from University of Zaragoza, University of Minho and University of Tours and aims at the isolation of native yeast strains from berries of the wine region Douro, UNESCO World Heritage, towards the production of wines that stand out in the market for their authenticity and for reflecting their region of origin in their aroma.

Evaluation of the effects of pruning methodology on the development of young vines 

Grapevine pruning is one of the most important practices in the vineyards. Winegrowers use it to provide the vines the shape needed, or to maintain it once achieved, and also to balance vegetative growth and fruit production. In the last decades, careless pruning has been blamed, among other factors, as responsible of the vineyard decay that is been observed even in young vines. However, to our knowledge, there is a lack of systematic research trying to elucidate to which extent the pruning method used affects plant development or its susceptibility to grapevine trunk diseases (GTD). Within this context, the aim of this work is to study the influence of different pruning method strategies on the development of field-planted young vines.

Water and nutritional savings shape non-structural carbohydrates in grapevine (Vitis vinifera L.) cuttings

Global changes and sustainability challenge researchers in saving water and nutrients. The response of woody crops, which can be forced at facing more drought events during their life, is particularly important. Vitis vinifera can be an important model for its relevance in countries subjected to climate changes and its breeding, requiring cuttings plantation and strong pruning.

Glucosidase and esterase salivary activities and their involvement in consumer’s wine sensory perception and liking

Wine flavour is the integration of distinct physiologically defined sensory systems that combine taste, aroma and trigeminal sensations, and it is a key determinant factor for the acceptance of wine by consumers. Volatile compounds, are important contributors to wine flavour, specially to aroma. These small and low-boiling point compounds are easily released into the air allowing to enter and move within the nasal or oral cavities where they can bind the olfactory receptors. Additionally, wine also contains aroma precursors, which are non-volatile compounds, but that can be broken down releasing volatile odorants. During wine tasting, all these chemicals (volatiles and non-volatiles) can be submitted to the action of salivary enzymes.

Phenotyping bud break and trafficking of dormant buds from grafted vine

In grapevine, phenology from bud break to berry maturation, depends on temperature and water availability. Increases in average temperatures accelerates initiation of bud break, exposing newly formed shoots to detrimental environmental stresses. It is therefore essential to identify genotypes that could delay phenology in order to adapt to the environment. The use of different rootstocks has been applied to change scion’s characteristics, to adapt and resist to abiotic and biotic stresses[1].
