20 hulless barley lines were assessed by grain yield and other agronomic traits in 2006 and 2007 in the research station of the university of tabriz, iran. the experiments in each year were carried out as randomized complete block design with four replications. the genotypes were significantly different for most of the studied traits. this indicated the existence of large genetic variation in t...

Rice grain yield is predicted to decrease in the future because of an increase in tropospheric ozone concentration. However, the underlying mechanisms are unclear. Here, we investigated the responses to ozone of two rice (Oryza Sativa L.) cultivars, Sasanishiki and Habataki. Sasanishiki showed ozone-induced leaf injury, but no grain yield loss. By contrast, Habataki showed grain yield loss with...

Rice (Oryza sativa) is the primary food source for more than one-half of the world's population. Because rice cultivation is dependent on water availability, drought during flowering severely affects grain yield. Here, we show that the function of a drought-inducible receptor-like cytoplasmic kinase, named GROWTH UNDER DROUGHT KINASE (GUDK), is required for grain yield under drought and well-wa...

Correlation coefficient analysis conducted on 22 triticale x bread wheat derivatives along with six checks to select true- breeding derivative(s) for future hybridization programme with tolerance to drought and cold stress conditions as well as better quality traits revealed significant correlation of grain yield with spikelets per spike, biological yield, harvest index, leaf area index. Intere...

The remobilization of water soluble carbohydrates (WSC) has an important role for grain yield. This study investigated the accumulation and remobilization of WSC in non-leaf organs (chaff, upper stem, and lower stem) and their contribution to grain yield, under different irrigation levels (rainfed, reduced irrigation, and full irrigation) and seeding rate treatments (450, 600 and 750 plants...

European agriculture suffers from a substantial deficit of protein sources forlivestock and the projected changes in agro-climatic conditions in Central Europeinclude a higher risk of drought. To address these challenges, the drought resistantlegume crop chickpea was compared with pea, barley and oat regarding its nitrogen(N) yield, protein yield and N use and utilization efficiency under Centr...

in order to determine the optimum planting date under deficit output area, this research was carried-out in 2010-11 and 2011-12 cropping seasons, in split-plot arrangement, using complete randomized block design with three replications in khuzestan agriculture and natural resource research center. main and sub plots were consisted of four planting dates (oct. 27 with 10 days interval) and four ...
