The aim is to explore the effectiveness of hyperspectral imaging in detecting water stress in grapevines and its relation to stem water potential.
Conducted over two growing seasons in 2024 and 2025 with 18 potted plants.
Images acquired using a Specim IQ camera over multiple dates.
Water-deprivation treatments applied to evaluate spectral responses.
A significant change in water potential was identified between 10 and 13 June.
PCA analysis indicated specific spectral regions linked to pigments and water content as key indicators.
HSI demonstrated potential as an early detection tool for water stress in grapevines.
