Non‐destructive assessment of grapevine water status in the field using a portable <scp>NIR</scp> spectrophotometer

Abstract

The capability of non-invasive NIR spectroscopy to reliably assess the grapevine water status under field conditions was proved. This technique can be a suitable and promising tool to appraise within-field variability of plant water status, helpful to define optimised irrigation strategies in the wine industry. © 2017 Society of Chemical Industry.
