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

Effect of Restricted Irrigation on Water Relation Traits and Antioxidant Activity

“…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.…”

“…Karami et al 2013 find genotype whose maintain water status had more in antioxidant activity under drought condition. Behbahanizadeh, et al (2014) and Ram et al (2017) also reported that under drought stress conditions (moderate stress and severe stress) RWC, osmotic potential and water potential reduced in contrast to control condition and cultivars had a significant difference together in water relation traits.…”

“…However, in many regions of world, wheat faces heat stress at reproductive stage prominently (Barnabas et al, 2008;Sunita et al, 2017). Heat stress causes reduction in wheat yield by accelerating growth, shorten the phasic development stages duration and net assimilation reduction due to carbon starvation (Blum, 1988;Hall, 1992;Shpiler and Blum, 1991;Ram et al, 2017). In temperate environment 40% falls in yield occurs under heat stress which extends over 36 million ha (Reynolds et al, 2001).…”
