leaf rolling, especially in cereals, mechanisms for reducing the light receiving surface of the leaves to reduce transpiration rate in response to drought caused. to investigate the effect of drought stress on leaf rolling and leaf anatomical characteristics, yield and yield components in field experiment was conducted bahonar university . in this experiment, five varieties of wheat (shole, omi...

an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...

salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...

Knowledge of genetic and phenotypic association among economic traits helps plant breeders in outlying efficient breeding strategies for development high yielding wheat variety. An experiment on 238 progenies along with parents was conducted to determine the correlation path coefficient analysis yield its attributing wheat. The result reveals presence variability Grain per had showed significan...

In order to explore a fertilization scheme that can adapt different soil fertility conditions and wheat varieties, two kinds of controlled-release ureas with release periods (60 days (CRU-60 d) 90 (CRU-90 d)) blending ordinary urea were applied in proportions at three sites evaluate the impacts bulk fertilizer (CRBBF) on NO3–N, NH4+-N contents dynamic change tillers, SPAD value, grain yield com...
