Variations in physiological traits as screening tool for drought tolerance in barley (Hordeum vulgare L.)

Combine Effects of Drought and High Temperature on Water Relation Traits in Wheat Genotypes under Late and Very Late Sown Condition

“…All through there were significant difference in osmotic potential among the genotype and treatments, the interaction between genotype and treatment were significant in all three environments. Our results are in agreement with those of Siddique et al, (2000) and Akram, 2011 in wheat andSharma et al, (2016) in barley found decrease in osmotic potential on the onset of stress.…”

Effect of Restricted Irrigation on Water Relation Traits and Antioxidant Activity

“…Genotype BH 14-08 and BH 13-10 had maximum relative water content at both growth stage flag leaf and anthesis respectively. Our finding is accordance with those of Kumar and Sharma, (2010) and Sharma et al (2016) observed reduction in relative water content when crop was imposed under drought environment. Karami et al 2013 find genotype whose maintain water status had more in antioxidant activity under drought condition.…”

“…Genotype BH 14-08 and BH 13-10 had maximum osmotic potential at both growth stage flag leaf and anthesis respectively. Our results are in agreement with those of Sharma et al (2016) in barley and Ram et al 2017 in wheat found decrease in osmotic potential on the onset of stress. Hein et al (2016) also observed significant difference in osmotic potential between drought and in control plants, OP was lowest in the flag leaf, whereas after the 4-days drought treatment, OP had dropped subsequently in the flag leaf.…”

“…expressed in terms of relative amount of water content, water potential and osmotic potential (Sabir et al 2008;Javed et al 2011). During water stress reduction was found between osmotic potential (Zhang et al (2015), water potential (Iqubal et al (2014) and relative water content (Vaezi et al 2010) in barley genotypes (Sharma et al, 2016;Aboughadareh et al 2017). When plant expose to adverse environment (drought) reactive oxygen species (ROS) such as superoxide (O 2 • ), hydrogen peroxide (H 2 O 2 ), hydroxyl radicals (OH • ) and singlet oxygen ( 1 O 2 ) are produced (Faize et al 2011).…”

Polymorphism of microsatellite markers in barley varieties contrasting in response to drought stress

“…Plants develop different adaptive changes in morphological and physio-biochemical processes, such as changes in plant structure, growth rate, tissue osmotic potential and antioxidant defenses, which inhibit or remove the harmful effects of stresses (Jackson et al 1996). Recently, several barley varieties have been assessed for their stress adaptation at physiological, biochemical and molecular level (Ahmed et al 2013;de Mezer et al 2014;Sharma et al 2016). Differences in resistance to drought stress are known to exist among genotypes of plant species.…”
