    Recent trends show reductions in crop productivity worldwide due to severe climatic change. Different abiotic stresses significantly affect the growth and development of plants, leading to decreased crop yields. Salinity and drought stresses are the most common abiotic stresses, especially in arid and semi-arid regions, and are major constraints for barley production. The present review attempts to provide comprehensive information related to barley plant responses and adaptations to drought and salinity stresses, including physiological and agronomic, in order to alleviate the adverse effect of stresses in barley. These stresses reduce assimilation rates, as they decrease stomatal conductance, disrupt photosynthetic pigments, reduce gas exchange, enhance production of reactive oxygen species, and lead to decreased plant growth and productivity. This review focuses on the strategies plants use to respond and adapt to drought and salinity stress. Plants utilize a range of physiological and biochemical mechanisms such as adaptation strategies, through which the adverse effects can be mitigated. These include soil management practices, crop establishment, as well as foliar application of anti-oxidants and growth regulators that maintain an appropriate level of water in the leaves to facilitate adjustment of osmotic and stomatal performance. The present review highlighted the adverse effect of drought and salinity stresses barley and their mitigation strategies for sustainable barley production under changing climate. They review also underscored that exogenous application of different antioxidants could play a significant role in the alleviation of salinity and drought stress in plant systems.

    QUALITY TRAITS PERFORMANCE OF BREAD WHEAT GENOTYPES UNDER DROUGHT AND HEAT STRESS CONDITIONS
    (Parlar Scientific Publications (P S P), 2016) Barutcular, Celaleddin; Yildirim, Mehmet; Kocl, Mujde; Dizlek, Halef; Akinci, Cuma; El Sabagh, Ayman; Saneoka, Hirofumi
    The current study aimed at assessing grain quality traits under stress environments and to determine the superior wheat varieties with high quality traits and tolerant/sensitive to harsh environment. Sixteen spring wheat genotypes were grown under two temperature levels (cool and warm) and two regimes (rain-fed and irrigated) in the experimental area of Dicle University, Turkey. The analysis of variance showed that genotypes and environment were found to significantly influence all quality parameters as major effects. Rain-fed environment (water stress) caused a significant reduction in grain quality traits except grain protein and dry gluten contents. Warm environment (heat stress) caused significant reductions in grain weight, grain starch content, test weight, gluten index and grain flour content. Hence, delayed sowing associated with high temperature resulted in overall increase in protein content, dry gluten content and Zeleny test. In respect to genotypes, significant differences in quality parameters were found and performance of Inqilab-91, Cham-6, Adana-99 and Meta-2002 were better in respect of most traits under different conditions. It is also opined that Inqilab-91, Cham-6, Adana-99 and Meta-2002 are healthier and better responsive genotypes in respect of grain quality under adverse environment (water stress and heat stress).
