TL;DR: In this article, the effect of drought stress on grain growth and yield of barley was studied in a greenhouse experiment, and the authors concluded that postanthesis drought stress was detrimental to grain yield regardless of the stress severity.

TL;DR: Investigation of the growth performance and grain yield of four barley cultivars under late-terminal drought stress under both glasshouse and field conditions found cultivar differences in grain yield were related to spike number per plant and grain number per spike, but not days to heading or grain filling duration.

TL;DR: Drought stress decreased seed size in the greenhouse experiment, but not in the field experiment, and an increase in nutrient concentrations in seeds from drought-stressed plants compared with well-watered plants for seeds similar in sizes indicates that the increase in Minerals in Seeds is not necessarily due to a reduction in dry matter accumulation.

TL;DR: This chapter helps plant breeders to select drought tolerant traits by understanding the correlations between pollination, yield, yield components and seed quality under drought stress at reproductive stage and to explain how drought stress effects final yield and seedquality during this stage.

TL;DR: The results indicate a unique pattern of activity and gene expression of the antioxidant enzymes in the two barley genotypes under controlled severe drought and suggest that each genotype utilizes different molecular and biochemical responses under the same drought conditions.
