in order to evaluate the effect of drought stress on grain yield and its components of fennel accessions, a field experiment was conducted as a split plot based on complete randomized block design with three replications. this experiment was conducted in research farm of agricultural faculty of zanjan university in 2012. in this study water stress in two levels included control and drought stre...
In order to study the effect of drought stress and determination of effective traits on grain yield of wheat in normal and terminal drought stress conditions, 82 wheat genotypes were studied in two separate experiments using randomized complete block design with three replications during cropping season 2011-2012. Drought stress was applied in heading stage by limited irrigation. Set of 22...
Grain weight, which is controlled by quantitative trait loci (QTLs), is one of the most important determinants of rice yield. Although many QTLs for grain weight have been identified, little is known about how different alleles in different QTLs coordinate to determine grain weight. In the present study, six grain-weight-QTLs were detected in seven mapping populations (two F2, one F3, and four ...
Seedling root traits of wheat (Triticum aestivum L.) have been shown to be important for efficient establishment and linked to mature plant traits such as height and yield. A root phenotyping pipeline, consisting of a germination paper-based screen combined with image segmentation and analysis software, was developed and used to characterize seedling traits in 94 doubled haploid progeny derived...
in order to study the effects of irrigation water salinity and leaching fraction on soil chemical characteristic, grain yield, yield components and sodium and potassium contents in leaves of safflower, an experiment was coducted in a split plot design with four replications in 2009 at roudasht, isfahan. treatments included three irrigation water salinities of q1=3.35, q2=8.77 and q3=11.21 ds/m ...
to investigate the effect of wild mustard plant density and nitrogen fertilizer on morphological characters, yield and yield components of canola a split-plot experiment based on a randomized complete block design with 3 replications was carried out in bu-ali sina university of hamedan, in 2009. 4 levels of nitrogen fertilization (100, 150, 200 and 250 kgn h-1) were assigned to main-plots and p...
To investigate the effect of nitrogen and zinc elements on the quantity and quality characters of sunflower plants (Jamah1cultivar), a factorial experiment in a randomized complete block design with three replications was conducted at the University of Zabol, Zabol, Iran in 2013. The experiment consisted of three nitrogen levels: 100, 200 and 300 kg ha-1 as the first factor and three levels of ...
the present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. to this end the experiment was conducted in 2010-2011 in south west of iran as split plots based on randomized complete block design with three replications. main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...
Biomass yield of rice (Oryza sativa L.) is an important breeding target, yet it is not easy to improve because the trait is complex and phenotyping is laborious. Using progeny derived from a cross between two high-yielding Japanese cultivars, we evaluated whether quantitative trait locus (QTL)-based selection can improve biomass yield. As a measure of biomass yield, we used plant weight (aboveg...
In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...
