“…Lu reported that DS significantly decreases the proportion of A‐type to B‐type starch granules, amylopectin content, and starch and grain yield . DS also influences starch size distribution and branch chain length in barley grains during anthesis . Although studies showed that starch from drought‐treated wheat contains low amylose, Zhang et al showed that DS does not affect amylose content after anthesis .…”

“…In other settings, salinity limits crop varieties suitable for irrigated soils and affects crop development and yield (Katerji et al, 2003). It also affects river, stream, and wetland ecosystems (Hart et al, 1990), impacts of climate change on river ecosystems (Suen and Lai, 2013), river diversions and ecology (Das et al, 2012), river environmental flow requirements (Sun et al, 2009), tolerance of macro-invertebrate and the ecosystem protection trigger values (Dunlop et al, 2008), sustainability of agricultural landscapes, carbon sequestration and biodiversity values (George et al, 2012), vegetation-groundwater interactions (Humphries et al, 2011), pesticide toxicity, ecosystem functions and ecosystem services (Schafer et al, 2012), bioavailability of Cu and Zn and other essential plant micronutrients (Speelmans et al, 2010), and causes changes in grain ultrastructure, amylase, protein and amino acid profiles under water, salinity, and combined stresses (Ahmed et al, 2013). These myriad ecosystem health linkages do imply that under shallow groundwater conditions salinity has implications for river basin health and ecosystems and thus imposes carrying capacity constrains in terms of water-savings and unlocking the potential of groundwater development for irrigation.…”

a b s t r a c tThis paper analyzes the effect of the shallow water table on water use of the winter wheat (Triticum aestivum L.) that has replaced alfalfa (Medicago sativa) on the irrigated lands of the Fergana Valley, upstream of the Syrdarya River, in Central Asia. The effect of the shallow water table is investigated using HYDRUS-1D. Numerical simulations show that the contribution of the groundwater to evapotranspiration increases with a rising water table and decreases with increasing irrigation applications. Under irrigation conditions, an increase in the groundwater evapotranspiration is associated mainly with an increase in evaporation loss, causing a buildup of salinity in the crop root zone. Evaporation losses from fields planted with winter wheat after the harvest amount up to 45-47% of total evaporation thus affecting soil salinity and ecosystem health. Promoting the use of groundwater for irrigation in order to lower the groundwater table is suggested to achieve water savings from the change in the cropping pattern. Unlocking the potential of groundwater for irrigation in the Fergana Valley can also contribute toward managing soil salinity and improving the health and resilience of water, land and ecosystems of water, land and ecosystems (WLE).

“…The increased Car content might actively participate in ROS detoxification with pro longed drought stress. It is widely accepted that protein content is an important indicator of reversible and irreversible changes in metabolism, which respond to a wide variety of stressors [28,29]. Zadra nik et al [28] reported that the levels of a number of proteins involved in various cellular pathways are affected during drought stress in common bean.…”

In order to study the potential antioxidant defense mechanisms, the blackberry cultivar 'Ningzhi 1', a new floricane fruiting hybridberry (Rubus sp.), was subjected to 20 day drought stress by withholding irri gation, followed by rewatering for 5 days, then the leaf water content (LWC), membrane electrolyte leakage, contents of photosynthetic pigments, protein, soluble sugar, hydrogen peroxide (H 2 O 2 ), and MDA, activities of superoxide dismutase (SOD) and peroxidase (POD), and the levels of antioxidants such as ascorbate (AsA) and reduced glutathione (GSH) in leaves were investigated. The results showed that LWC was greatly decreased during the 20 day drought treatment period. After rewatering, water content restored. Drought stress induced significant accumulation of photosynthetic pigments, protein, soluble sugar, H 2 O 2 , and MDA as well as an increase in membrane electrolyte leakage, which were all decreased after rewatering. The activ ities of SOD and POD were elevated under drought stress, which were still at higher levels compared with control after rewatering. The contents of AsA and GSH ascended first and were then followed by a decline during the whole drought period, after rewatering, the contents increased and remained at a higher level than that of controls. The plants showed a rapid and almost complete recovery after rewatering, and the physiolog ical alterations could represent a set of adaptive mechanisms employed by 'Ningzhi 1' to cope with drought stress. It was suggested that increased drought tolerance of 'Ningzhi 1' was due to higher antioxidant enzymes, reduced lipid peroxidation, better accumulation of osmolytes, and maintenance of tissue water content.
