Barley crop grown in semiarid areas may experience water deficit especially during grain filling that makes them more dependent on stem water-soluble carbohydrates (WSC). Fructans are the most important reserved carbohydrates. A pot experiment was undertaken at Shahid Chamran university in the duration of 2010-2011 growing seasons to investigate the accumulation and loss of WSC and the activity...

Due to climate change, multiple heat events are expected be an additional limiting factor that will adversely affect wheat production. The study aimed analyze the physiological response stress in four winter cultivars at different stages under greenhouse conditions during 2019. net photosynthetic rate, stomatal conductance, chlorophyll index, maximum quantum efficiency of photosystem II, fructo...

To determine salt sensitivity for wheat at various growth stages, a factorial experiment arranged as randomized complete block design was conducted in the ambient environment at the National Salinity Research Center, Yazd, Iran. Treatment were two cultivars of wheat (Kavir & Roshan) and salinity imposed at emergence, tillering, stem elongation, spike emergence and one week after anthesis. A con...

in order to evaluate the effect of terminal water deficit stress on leaf traits and their relations to grain yield in different barley genotypes (‘yousof’, ‘fajr30’, ‘nosrat’, ‘pbyt-46’, ‘pbyt-97’ and ‘morocco’), two separated experiments were conducted in stress (water withholding from anthesis towards the end of growing season), and non stress (normal irrigation) conditions based on rcbd with...

Genotypic variation in ear morphology is linked to differences in photosynthetic potential to influence grain yield in winter cereals. Awns contribute to photosynthesis, particularly under water-limited conditions when canopy assimilation is restricted. We assessed performance of up to 45 backcross-derived, awned-awnletted NILs representing four diverse genetic backgrounds in 25 irrigated or ra...

High temperature stress during grain filling substantially decreases wheat productivity; thus, to ensure food security, heat tolerance in must be developed. It remains unclear whether exogenous salicylic acid (SA) can induce high temperatures at the grain-filling stage. In this study, a two-year pot culture experiment using cultivar ‘Yangmai 18’ was conducted from 2018 2020. The plants were pre...
