Resumo(s)
In this study the experimental vineyards are located in Quinta do Aroeira (Lisboa, Portugal) and a randomized complete block design was established. Samples derived from two different training systems “Low Cordon” (LC) and “High Cordon” (HC) and four different amounts of municipal solid organic waste were analyzed in terms of yield parameters, grapes and must qualitative characteristics and basic analytical parameters, phenolic composition, and chromatic characteristics of the wines.
The results showed that samples treated with mechanical pruning on LC training system had lower alcohol content and pH values. Furthermore, it negatively influenced the non-flavonoids content, while promoted the interaction between anthocyanins and flavonols. The color was decreased in blue tonalities and this was obvious by human eyes.
The organic treatment with the most significant effect in wine quality was M3 (highest supply of municipal solid waste), The treatment with M3 resulted in the decrease of alcohol and color intensity of the wines
