“…The Yara ZIMprobes were installed in mature leaves located in the east side of the canopies. In order to distinguish between relative changes in leaf turgor caused by water stress and those caused by microclimate variations (Zimmermann et al 2013a), relative humidity (RH) and T a sensors (Yara ZIM Plant Technology GmbH (Hennigsdorf, Germany) were also installed in the orchard. All probes (leaf turgor, T a and RH) were connected by cable to transmitters which sent the data wirelessly every 5 min over a distance of up to 1500 m to a central controller (Yara ZIM Plant Technology GmbH Hennigsdorf, Germany).…”

Changing global climatic conditions and irrigation water shortages impose water stress conditions on crops. To develop genotypes tolerant to water stress necessitates reliable high-throughput methods to study plant water status and water stress tolerance mechanisms. We report the use of a non-destructive, automated, precise and rapid system for assessing real-time water status in canola plants. Leaf patch clamp pressure probes were clamped on the leaves of four different genotypes of canola grown under field conditions. The data generated diurnal curves characterizing the pattern of turgor pressure maintenance within the leaves. A novel methodology termed 'inverse hysteresis' was developed to measure relative water stress levels in plants using the probe-derived data. The inverse hysteresis data show that genotypes CT12 and CT15 had a higher ability to withstand water stress and were more tolerant to water stress than DS23 and DS35. The chlorophyll content and seed yield were also higher in CT12 and CT15. This novel analytical tool for monitoring water status in canola plants will be of great benefit in other crop species to efficiently screen genotypes for water stress tolerance.

“…Several plant-based techniques have been studied during the last decades to continuously monitor the plant water status in crops of a high economical interest (Fernández, 2014). These techniques, such as the leaf/stem water potential, stem dendrometers or the sap flow measurements, among others, present however some practical issues that prevent their regular use in the field (Zimmermann et al 2013a). __________________________________________ a E-mail: ballester_carlur@gva.es Leaf turgor monitoring with a magnetic-based probe (ZIM-probe) has been pointed out as a promising alternative to the aforementioned techniques (Zimmermann et al 2008).…”

Further improvement on irrigation management requires continuous plant water status monitoring. The non-invasive ZIM-probe measures the pressure (Pp) transfer function through a patch of an intact leaf, which is inversely correlated with the turgor pressure. Data are sent wireless in real-time by telemetry to an Internet server via a mobile phone network where it is available to be analyzed. In this work, the detection of water stress by measuring relative changes in turgor pressure with the ZIM-probe was evaluated in clementine and persimmon trees. Ten trees of both species were equipped with two ZIM-probes each located at the east side of the canopy. The ZIM-probes were used over several months during which half of the trees were subjected to two drought cycles. Concomitant measurements of stem water potential (ψs) were taken at midday in both orchards during the drought periods. Additionally, determinations of ψs and stomatal conductance (gs) were also performed during 1-2 days at hourly intervals in the clementine and persimmon orchards, respectively, to study the existing relationship of these classical indicators with the leaf turgor pressure. Results showed that diurnal Pp values increased in nonirrigated clementine trees when water restrictions were imposed. Persimmon drought-stressed trees, on the other hand, showed different Pp curve shapes (half and complete inverse curve) depending on the level of stress reached by the trees. There was a tight correlation between the hourly spot measurements of ψs and gs with the probe data. Overall, results show that the ZIM-probe enables the detection of drought stress in clementine and persimmon trees. Nevertheless, different approaches for calculating the water stress level must be used in each of these species due to the higher tendency of persimmon leaves to the inversed Pp curve phenomena.
