Rice (Oryza sativa L.) is a staple food supplying nutrition for more than half of the world’s population. Amylose content (AC) is widely considered as the most important factor determining rice grain quality for cooking, eating and processing. Field experiments of 32 rice varieties of different ecotypes grown under artificial drought stress from 30 days after transplanting to maturity and well ...
Understanding crop response to manipulations in source (number of leaves) and sink (panicle) during the growing season provides useful information develop breeding strategies. In present study, we assessed how source-sink manipulation can affect sorghum (Sorghum bicolor L.) yield its components—grain number grain weight (including filling dynamics)—for hybrids released past 60 years. The field ...
Breeding programs with the aim to enhance yield productivity under abiotic stress conditions during the reproductive stage of crops is a top priority in the era of climate change. However, the choice of exploring stay-green or senescence phenotypes, which represent an opposing physiological bearing, are explored in cereal breeding programs for enhanced yield stability to a different extent. Thu...
Grain filling in sunflower (Helianthus annuus L.) mainly depends on actual photosynthesis, being the contribution of stored reserves in stems (sucrose, hexoses, and starch) rather low. Drought periods during grain filling often reduce yield. Increasing the capacity of stem to store reserves could help to increase grain filling and yield stability in dry years. Fructans improve water uptake in s...
In order to evaluate the effect of seed priming and application of cytokinin and auxin on grain yield of wheat cv. Chamran, an experiment was carried out in Agriculture Faculty of Shahid Chamran University of Ahvaz, Iran, during 2015-2016 and 2016-2017 growing seasons. Experiment was carried out in a factorial arrangement based on randomized complete block design with three replications. Treatm...
