Stomatal closure induced by water deficit
reduces leaf transpiration rate, and consequently results in reduced evaporative cooling and increased leaf temperature (Berni et al., 2009).
stamineus leaves and stem biomass yield may not be affected by water deficit
treatments over the two weeks period.
However, the application of water deficit
in such intensity (ADH2) caused an increase in the diameter, except Hedba3 genotype, which exhibited a regression in its diameter under these conditions.

in leaves," Australian Journal of Biological Sciences, vol.
Other studies over the past 60 years suggest that the topsoil (where most of the root activity and nutrients usually are) should remain moist for optimal pasture growth, and that the soil water deficit
should be kept below ~20 mm.
A moderate water deficit
could significantly improve fruit quality (in terms of TSS content and perhaps acidity) of deficit irrigated tomato of Melka Shola and Melkassa Marglobe by 10% and 15%, respectively without depressing marketable yields in relation to fully irrigated treatments.
The role of cell wall adjustment in plant resistance to water deficits
(Review and Interpretation).
In effect, the region's water deficit
can be thought of as another Nile flowing into the region in the form of imported food.
Ascorbate peroxidase activity and the amount of ascorbate were elevated in water deficit
treatments relative to the full irrigation during Year 2.
There were no significant changes in hematocrit measurements, indicating that subjects did not have a significant water deficit
Deciduous plants subjected to drought in seasonally-dry environments may display a range of responses that are thought of as adaptive to water deficit
. Frequent responses of plants to drought include leaf rolling, paraheliotropic movements and increase in leaf reflectance (Begg, 1980; Ehleringer, 1980).
