The study aimed to test whether night‐time transpiration provides any potential benefit to wheat plants which are subjected to salt stress. Hydroponically grown wheat plants were grown at four levels of salt stress (50, 100, 150, and 200 mM NaCl) for 5–8 days prior to harvest (day 14–18). Salt stress caused large decreases in transpiration and leaf elongation rates during day and night. The quantitative relation between the diurnal use of water for transpiration and leaf growth was comparatively little affected by salt. Night‐time transpirational water loss occurred predominantly through stomata in support of respiration. Diurnal gas exchange and leaf growth were functionally linked to each other through the provision of resources (carbon, energy) and an increase in leaf surface area. Diurnal rates of water use associated with leaf cell expansive growth were highly correlated with the water potential of the xylem, which was dominated by the tension component. The tissue‐specific expression level of nine candidate aquaporin genes in elongating and mature leaf tissue was little affected by salt stress or day/night changes. Growing plants under conditions of reduced night‐time transpirational water loss by increasing the relative humidity (RH) during the night to 95% had little effect on the growth response to salt stress, nor was the accumulation of Na+ and Cl− in shoot tissue altered. We conclude that night‐time gas exchange supports the growth in leaf area over a 24 h day/night period. Night‐time transpirational water loss neither decreases nor increases the tolerance to salt stress in wheat. [ABSTRACT FROM AUTHOR]

Purpose – Both anecdotal and empirical evidence indicates that even well-intentioned eyewitnesses can make inaccurate identifications resulting in erroneous prosecutions and wrongful convictions. The risk of erroneous identification increases when witnesses are asked to identify people belonging to other races. The purpose of this paper is to evaluate the policies which enhance the likelihood of obtaining accurate identifications from eyewitnesses. Legal implications especially relevant to police administrators in the USA including constitutional considerations and risks of civil liability are integrated with the empirical record and used to make policy recommendations likely to decrease legal and public relations entanglements for police. Design/methodology/approach – This paper integrates an empirical literature review with legal research and analysis in order to advocate for prudent policy reforms. Findings – Both the empirical record and current US law indicate that police administrators would be well-advised to require serial, double-blind identification procedures where witnesses are routinely warned about the perpetrator’s potential absence and required to give immediate certainty statements. Officers should be prohibited from using the same suspect with the same witness more than once and should be provided with training on the inherent dangers of inaccuracy associated with cross-racial identifications. Originality/value – While a significant amount of material concerning eyewitness identification exists, most of the existing work does not integrate legal realities, especially those concerning civil liability, within the framework of the eyewitness identification literature. Nor does past work contextualize the need for reform with the emerging racially charged atmosphere in which US police must currently work. [ABSTRACT FROM AUTHOR]
