The impact of terminal heat stress on yield and heat tolerance of bread wheat
In arid and semi-arid regions of the world bread wheat (Triticum aestivum L.) yield is highlylimited due to late season heat stress, mostly occurring during the reproductive phase. Hence thecurrent study was conducted to evaluate the effect of late season heat stress on grain yield andyield components of 20 spring bread wheat cultivars. For this purpose, a stripe block experimentincluding four ...
متن کاملاثر تنش گرمای آخر فصل بر رشد دانه و عملکرد کمی و کیفی گندم نان بهاره در اهواز
Terminal heat stress in hot and dry conditions like Ahwaz reduces the quantitative and qualitative yield of wheat. In order to study the effect of terminal heat stress on grain filling period duration, grain filling rate and quantitative and qualitative yield of 20 spring bread wheat cultivars, a field experiment was conducted in Research Farm of Agricultural Sciences and Natural Resources Univ...
متن کاملEvaluation of growth, yield, relative performance and heat susceptibility of eight wheat (Triticum aestivum L.) genotypes grown under heat stress
Eight spring wheat cultivars were evaluated under three heat stress conditions (early, late and very late) in order to identify suitable cultivars to develop heattolerant genotypes resistant to future global warming. Results from the study indicate that stress did not negatively affect flag leaf area in ‘Prodip’ and ‘Sufi’, flag leaf dry matter partitioning in ‘Prodip’, ‘BARI Gom-26’ and ‘S...
متن کاملThe Study of temperature depression and its association with grain yield in six wheat cultivars under heat stress conditions and salicylic acid application
In order to evaluate canopy and organs temperature depression (TD) under heat stress conditions and the effects of plant morphology on organs temperature depression and their association with grain yield, two field experiments were conducted using six wheat cultivars (Behrang, Chamran, Kauz, Koohdasht, Karim and Montana) planted on three dates (early, optimum, late) in 2014-2015 and 2015 -2016 ...
