Apr 15, 2022 · Measurements of plant water relations are usually obtained using standard techniques such as relative water content (RWC) and “pressure chamber” to measure mid-day or pre-dawn leaf (ΨL) or stem water potential (Ψstem) (Lampinen et al., 2001).
May 26, 2021 · This paper reviews the different remote sensing techniques found in the literature to monitor plant water status, allowing farmers to control the irrigation management and to avoid...
Nov 7, 2019 · Here, we present a method for the estimation of RWC in plant leaves from non-contact resonant ultrasound spectroscopy (NC-RUS) data. This technique enables to collect transmission coefficient in a [0.15–1.6] MHz frequency range from plant leaves in a non-invasive, non-destructive and rapid way.
