Irrigation scheduling is critical as it affects both fruit yield and composition. We examined the
potential to use field-measured hyperspectral remote sensing data (reflectance and …

In rainfed vineyards water deficits play a major role in determining berry yield and
composition. Therefore, reliable indicators of vine water status might be of great value for the …

Several vegetation indices (VI) derived from handheld spectroradiometer reflectance data in
the visible spectral region were tested for modelling grapevine water status estimated by the …

Vine water status is widely considered to be fundamental to grape yield and quality. Typical
Mediterranean vineyards experience seasonal droughts so water deficits need to be …

Highlights•Field spectroscopy data processed by functional analysis predicts leaf water
content.•The best models were achieved for bands centred in the wavelengths 1265–1668 …

Efficient irrigation in viticulture requires objective and representative monitoring of the
vineyard water status variability. In this work the combination of multispectral, environmental …

The evolving spatial and temporal knowledge about vineyard performance through the use
of remote sensing offers new perspectives for vine water status studies. This paper …

Physiological measurements are considered to be the most accurate way of assessing plant
water status, but they might also be time-consuming, costly and intrusive. Since visible (VIS) …

In the Mediterranean arc, vines for wine production are mainly grown without the support of
irrigation. Under such conditions, site variables affecting the extent and seasonal timing of …

BACKGROUND Until now, the majority of methods employed to assess grapevine water
status have been destructive, time‐intensive, costly and provide information of a limited …
