In order to evaluation of influence of sulphur fertilizer on grain yield and the some of physiological indices of canola, an split plot experiment based on randomized complete block design was conducted in Research Farm Islamic Azad University, Ardabil branch in 2007. Factors were: sulfur fertilizer at four levels (0 as control, 25, 50 and 75 kg S/ha) in the main plots and canola cultivars at t...

to investigate the root anatomy and hydraulic conductivity of wheat cultivars, including shiraz, bahar, pishtaz, sistan, and yavaros, a series of controlled environment (growth chamber) experiments were hydroponically conducted at university college of dublin (ucd), ireland in 2010. bahar, pishtaz and sistan cultivars were employed as tolerant to drought and shiraz and yavaros as sensitive. twe...

secale cereale is a nosious, problematic weed of wheat fields in iran. for evaluation of the yield and yield components of bread wheat (triticum aestivum l.) cultivars in the presence of rye an experiment was established in a randomized compelet block design with factorial arrangment of treatments in meshkindasht and varamin during 2002-2003 growin season. experimental factors were wheat cultiv...

 DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...

Fusarium head blight (FHB) is a serious disease of wheat. The best controls for FHB are planting of resistant cultivars and application of fungicides to heads. However integrating these strategies may provide additional benefits for small grain producers including reduced disease losses and lower levels of the toxin deoxynivalenol (DON). This research was conducted to determine if resistant cul...

in order to evaluate the physiological and biochemical traits in response to salinity, six varieties of wheat were cultivated in a split plot based on randomized complete block design in the growth chamber in the department of agronomy, faculty of agriculture, university of maragheh. seedlings of wheat cultivars, in three to four leaves stage were treated with 200 mm nacl for 14 days. after the...

Fatty acid methyl esters (FAMEs) were used to `®ngerprint' soil microbial communities that evolved during 25 years of wheat-fallow cropping following native mixed prairie sod at Sidney, Nebraska, USA. Total ester-linked FAMEs (EL-FAMEs) and phospholipid-linked FAMEs (PL-FAMEs) were compared for their ability to discriminate between plots remaining in sod and those cropped to wheat or left fallo...

wheat grain yield is adversely affected by post-anthesis drought stress conditions in most wheat growing areas of iran. to evaluate the effect of late drought stress on wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of collage of agriculture, shiraz university during 2009-2010 growing season. ir...

ABSTRACT The selective effect of quantitative host resistance on pathogen aggressiveness is poorly understood. Because two previous experiments with a small number of bread wheat cultivars and isolates of Mycosphaerella graminicola had indicated that more susceptible hosts selected for more aggressive isolates, we conducted a larger experiment to test that hypothesis. In each of 2 years, six cu...
