Variability of Tempranillo grape composition in the Rioja DOCa (Spain) related to soil and climatic characteristics.

摘要: Background: Soil and climate are terroir elements that condition vine response. This research was intended to evaluate the variability of grape composition Vitis vinifera L. cv. Tempranillo in Qualified Designation Origin Rioja (DOCa) (Spain) La (Spain), its relationships with soil characteristics.; Results: The between (sugar content, acidity, phenolic compounds, berry weight) characteristics were analyzed for period 2008-2017 20 plots scattered throughout Alta Baja, using multiple-regression analysis. spatial effect properties evaluated cluster Despite high from year year, it possible define plot affect at ripening.; Conclusion: Acidity anthocyanin concentrations affected by temperature precipitation recorded different time periods growing cycle. increase earlier stages reduced total acidity increased polyphenols, while an during ripening produced a decrease malic acid, concentration, lower ratio anthocyanins sugars. located soils higher water availability presented concentrations. © 2018 Society Chemical Industry.; Industry.
