in order to study the effects of post – anthesis heat stress on source of six wheat genotypes (vee/nac, chamran, s79-10, dez, fong and kaveer), two separate field experiments were conducted as delayed as against optimum sowing dates in ahvaz coditions. plants in delayed sowing date experienced heat stress at post-anthesis growth stage. as study of grain yield indicated that the highest and the ...

the main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. we were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. if such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. in addi...

heat stress is a major environmental stress limiting wheat productivity in most cereal growing areas of the world. in order to map and characterize quantitative trait loci controlling heat tolerance, 144 recombinant inbred lines deriving from the cross of kauz and mtrwa116 were assessed in a greenhouse and growth chamber at 35°c. one hundred and sixty six ssr and 3 aflp markers were used to...

Contemporary theory suggests that prefrontal cortex (PFC) function is associated with individual variability in the psychobiology of the stress response. Advancing our understanding of this complex biobehavioral pathway has potential to provide insight into processes that determine individual differences in stress susceptibility. The present study used functional magnetic resonance imaging to e...

in order to investigate the responses of sardari wheat ecotypes to drought stress, 12 spikes of sardari wheat were selected from different regions of kurdistan province and planted as head to row. in the second year, a split- plot factorial field experiment was conducted. in this experiment water stress and irrigation were considered as the levels of main factor and 12 sardari wheat ecotypes al...

in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...

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...

abstract introduction: heat stress risk assessment, as a harmful agent at workplace, is essential for controlling heat strain and heat stress effectively. this study is concerned with the relationship between physiological strain index (psi) and wet bulb globe temperature index (wbgt) in women in the climate chamber . methods: this experimental study was carried out on 36 healthy females in sit...
