“…Perhaps this was due to higher water vapor pressure deficit (VPD) values (approx. 4.6 kPa) on the 28 th DAT (Klein et al, 2013;Hsie et al, 2015). The values of gs recorded here were close to those obtained for lettuce by Kim et al (2004).…”

“…), and some organic acids (Timpa et al, 1986;Girousse et al, 1996;Bray et al, 2000). Besides, the rate of photosynthesis, stomatal conductance, and transpiration substantially decline (Deeba et al, 2012;Pierantozzi et al, 2013) due to partial or complete closure of stomata (Hsie et al, 2015). Normally, the rate of assimilation and other gas exchange activities define growth and development of plants (Raines, 2011) but, drought and other environmental stresses affect them badly (Otieno et al, 2005).…”

Cotton is a drought tolerant plant which adapts the dehydrated conditions through significant ameliorations in its internal physiochemical activities. The objectives of present investigation were to examine its adaptive response to different intensities of dehydration stress under extreme arid climate of desert and quantify the extent of interactions between physiological and biochemical attributes in the course of drought adaptation. A micro scale field trial was conducted on southern oasis of Taklamakan desert, in which cotton was grown in soil buried 1 m 3 pots using four deficit irrigation levels. Results revealed that drought stress significantly enhanced the concentrations of abscisic acid (ABA), proline, total soluble sugars (TSS), and potassium ions (K +) in cotton leaves, while, rates of photosynthesis (A), stomatal conductance (gs.), and transpiration (E) declined. On an average, the plants replenished with 80, 60, and 40% irrigation, accumulated relatively 37, 98 and 155% more quantities of stress combating biochemical substances than normal plants, respectively. The stomatal density on abaxial leaf surface increased, while, aperture and leaf water potential significantly reduced. Consequently, the average rate of photosynthetic attributes reduced by 7, 32, and 52% at 80, 60 and 40% irrigation replenishments, respectively. These results suggested that decline in leaf gas exchange activities was indeed a modulating effect of drought induced osmoprotectants enrichment in leaf tissues, thus cotton plants adapted the drought intensities of desert environment. However, further micro irrigation based large scale studies on water use optimization of cotton under desert ambiances are inevitable.

The difference between leaf and outside air temperatures is highly responsive to the seasonal atmospheric weather variation 27 .

This study examines intraspecific variability among three sources (KSA, SD5.1 and SD6.2) of Balanites aegyptiaca in Saudi Arabia in their response to different watering frequencies and seasonal changes in vapour pressure deficit (VPD) and air-to-leaf temperature difference (T) under field condition. Irrigation was done once a week, once every two weeks or once every three weeks. Traits measured include: tree height, diameter (DM), relative monthly height (RMHI) and diameter (RMDI) increments, stomatal resistance (Rs), specific leaf weight (SLW). VPD and T were measured during the same time of Rs and SLW measurements. Both Rs and SLW directly responded to irrigation treatment and seasonal variation in T and VPD. Interactive effects of hot weather and water stress increased leaf temperature, resulting in less T and more VPD that induced higher Rs and SLW values. SD5.1 accounted for better responses under water stress, due to its higher Rs and SLW in the same time maintained better growth. DM and RMDI were more responsive to watering stress and varied among the sources. Early seedlings root-toshoot ratio was associated with better growth performance later in the field. The results highlight the role of hot weather and water stress in producing large changes in T and VPD that have a major impact on Rs and SLW. In addition, there is large intraspecific variation in field growth and adaptive responses among seeds brought from different provenances.
