Demand for water to irrigate crops is increasing due to rising global temperature and population growth, with 70% of fresh water already diverted to irrigation. This is expected to exacerbate water scarcity and increase water stress in many crop production regions.

Herbicide Uptake as Influenced by Plant Water Status
Pesticide Biochemistry and Physiology, 1996Abstract The effect of defined plant water status (relative water content) on the foliar influx of [ 14 C]2,4-D [(2,4-dichlorophenoxy)acetic acid] was studied in soybean ( Glycine max L.). A positive correlation between relative water content and leaf water potential was established with a regression coefficient r = 0.978. The foliar influx of 4.45 ×

The Water Status in the Plant Experimental Evidence
1976In Part 1:B and 1:C of this volume Oertli gives a detailed theoretical treatment of water in the plant body and in the soil-plant-atmosphere continuum. This leaves the task of providing quantitative data for at least some of the parameters discussed. The choice of these parameters and of the papers dealing with them has to be rather subjective, since ...

Carbon and plant water status in relation to water stress of rubber
2004Based on Thailand national policy to expand rubber plantations in northeastern and northern regions, the performance information under drought conditions need to be developed for this specie. Carbon exchange rate and plant water status of two popular commercial clones (RRIM 600 and RRIT 251) under non-water stress and water stress conditions were ...

Water Status in Plants — Methods of Measuring
1973The transpiration flux is envisaged as a catenary process, whereby water moves from the bulk of the soil, through the roots, stems, and leaves of plants to the atmosphere in response to an interplay of potential levels at the various point on the path, and of the resistances along the various segments of this path (Van Den Honert, 1948).

Plant water status monitoring with THz QTDS
2016 German Microwave Conference (GeMiC), 2016We demonstrate how water status measurements on plants can be performed using terahertz quasi time domain spectroscopy (THz QTDS). Compared with conventional THz TDS, this approach enables much more cost-efficient measurement setups and thus brings the technology closer to it's application in the field.

Estimation of plant water status with the beta-gauge
Agricultural Meteorology, 1973Abstract The β-gauge is a useful instrument for monitoring changes in plant water status, and it has also been used to estimate absolute water status. The effects of plant parameters such as variability of leaves, lateral leaf shrinkage, growth and ontogenetic changes, on the use of the technique for water status estimation in cotton were examined ...

Plant water status, hydraulic resistance and capacitance
1989Many excellent reviews have been written about plant water status and its measurement (e.g. Slatyer, 1967; Barrs, 1968; Boyer, 1969; Brown and van Haveren, 1972; Slavik, 1974; Turner, 1981). The reader is referred to these sources for a more complete review, particularly of the older literature.

Visual estimation of plant water status in cereals
The Journal of Agricultural Science, 1979SummaryThe potential offered for plant breeding programmes by visual scoring techniques for plant water status was investigated in rice and spring wheat. It was found that differing plant morphology could seriously bias visual estimates of leaf water potential, particularly in spring wheat. In spite of this problem, it was found that at least for rice,
