Assessment of vineyard water status variability by thermal and multispectral imagery using an unmanned aerial vehicle (UAV)

The goal of this study was to assess the water status variability of a commercial rain-fed Tempranillo vineyard ( Vitis vinifera L.) by thermal and multispectral imagery using an unmanned aerial vehicle (UAV). The relationships between aerial temperatures or indices derived from the imagery and leaf...

Zusammenfassung:	The goal of this study was to assess the water status variability of a commercial rain-fed Tempranillo vineyard ( Vitis vinifera L.) by thermal and multispectral imagery using an unmanned aerial vehicle (UAV). The relationships between aerial temperatures or indices derived from the imagery and leaf stomatal conductance ( g s ) and stem water potential (Ψ stem ) were determined. Aerial temperature was significantly correlated with g s ( R 2 = 0.68, p
