Unexpected relationships between vine vigor and grape composition in warm climate conditions

[Aim] The purpose of the research was to link vigor with grape composition in a climate change scenario. [Methods and results] This work presents a 4-year study (from 2010 to 2013) in a non-irrigated Tempranillo vineyard located in La Rioja (Spain). It is based on the acquisition of multi-spectral i...
