this study was carried out to evaluate empirical models of competition, as two separated experiments based on a randomized complete block design with 3 replications at agricultural faculty of bu-ali sina university, in 2008-2009. in both experiments, alvand and sayson cultivar were planted with densities of 450 plants m-2. in the 1st experiment, feral rye (secale cereale) with densities of 0, 2...

A study using 51 wheat, 56 barley and 34 oat grain samples was conducted to investigate the feasibility of predicting the apparent metabolizable energy (AME) value of these cereals for poultry. Stepwise regression analyses were performed to evaluate the relationship of AME with starch, ether extract (EE), crude fiber (CF), soluble sugar (SS), ash and crude protein (CP) (for wheat and barley gra...

orobanche aegyptiaca, commonly known as egyptian broomrape, is a holo-parasite that causes high economic damages on tomato production in iran. breeding for resistance is the most economic and feasible method to reduce broomrape infestation. 20 tomato cultivars and four wild tomato species were screened for o. aegyptiaca resistance. tomato yield reduction, dry weight reduction of shoot and root,...

to evaluate the competition between wheat and wild mustard (sinapis arvensis) in nitrogen and herbicide levels, an experiment was conducted in ramin agriculture and natural resources university, at 2007-8. a split-plots design in rcbd (randomized complete blocks design) with three replications was used for this experiment. the nitrogen levels (0, 60, 120 and 180kg/ha) arranged in main plots. ea...

Sleep and/or circadian rhythm disruption (SCRD) is seen in up to 80% of schizophrenia patients. The co-morbidity of schizophrenia and SCRD may in part stem from dysfunction in common brain mechanisms, which include the glutamate system, and in particular, the group II metabotropic glutamate receptors mGlu2 and mGlu3 (encoded by the genes Grm2 and Grm3). These receptors are relevant to the patho...

In this study, the interaction between iron and copper on growth parameters (plant height, fresh weight of roots, stem’s length, fresh weight of shoots, fresh and dry weight of seeds), total proteins and the antioxidant enzymes activity   in Cuminum cyminum L.  were investigated. This experiment was carried out in completely randomized blocks with 9 treatments in 3 repetitions.  Plants were tre...

Soluble and bound phenolic compounds were extracted from different varieties of millet types namely, finger millet, foxtail, and proso millet cultivated at dry and intermediate climatic zones in Sri Lanka. The extracts were examined for their total phenolic content (TPC), total flavonoid content (TFC), and proanthocyanidin content (PC). The antioxidant activities were meassured by reducing powe...

this experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (triticum aestivum l.) and durum (triticum turgidum l.) wheats in seedling stage. a greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. different agronomic and physiol...

Ornithine aminotransferase (OAT) is a reversible enzyme expressed mainly in the liver, kidney and intestine. OAT controls the interconversion of ornithine into glutamate semi-aldehyde, and is therefore involved in the metabolism of arginine and glutamine which play a major role in N homeostasis. We hypothesised that OAT could be a limiting step in glutamine-arginine interconversion. To study th...

Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...
