In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

To evaluate of the sunflower crushed in nutritional parameters in steers, supplemented at pasture, we used four steers in 4×4 Latin square design. The supplements were provided in 6 g/kg of body weight/animal/day, consisting of sunflower crushed, corn, soybean meal and mineral. All the supplements was isonitrogenous and soybean meal was replaced in 0, 20, 40, and 60% for sunflower crushed. The ...

Background: Staphylococcus aureus has always been known as an important kind of bacteria causing food poisoning. This study was carried out to determine S. aureus contamination in cream pastries collected from popular confectioneries in Hamedan, Iran; also, presence of the gene encoding Staphylococcal Enterotoxin A (SEA) was studied in the isolates. Methods: During April to October 2014 (as ho...

in order to evaluate the yield and advantage of two- and three-species intercropping of sunflower with corn and soybean, an experiment was conducted at the research farm of faculty of agriculture of tabriz university in tabriz, iran 2011. the experiment was arranged based on randomized completely block design with 6 treatments and three replications. treatments were included the pure stand of s...

Mexican sunflower is native to Mexico and Central America and was introduced into China early last century. Now it has widely naturalized and is exhibiting increasing invasiveness in South China. As this species often dominates bare ground, a habitat characterized by extreme fluctuation in temperature and water, it is reasonable to hypothesize that it has special adaptations to high temperature...

In order to investigate the mutation characteristics and to further examine the genetic variation of mutant sunflower (Helianthus annuus) obtained in plants grown from seeds exposed to space conditions, only the mature tissues such as leaf and flower could be used for DNA extraction after mutation characteristics were confirmed. The rich contents of polysaccharides, tannins, secondary metabolit...

INTRODUCTION The aim of study was to estimate the qualitative and quantitative composition of moulds colonizing sunflower seeds on RBCA, YpSs, DG18 media at 25, 37, and 45°C. MATERIAL Twenty samples of sunflower seeds (not roasted and not salted) were used for the analysis. The highest number of moulds were xerophilic species isolated on DG18 at 25°C (33), followed by mesophilic species (29) ...

This study reports the competitive adsorption of Ni(II), Cd(II) and Cr(VI) onto sunflower waste biomass carbons, viz. sunflower head carbon and sunflower stem carbon from multi-metal aqueous solution. The adsorption capacity of the adsorbents was highest in mono-metal system but decreased with increase in the number of coions. The adsorption capacity in mono-metal system was 0.32 and 0.45 mM/g ...

This study was undertaken to determine how photosynthesis tolerates desiccation in an intertidal alga Fucus vesiculosus L. and a terrestrial sunflower Helianthus annuus L. Photosynthetic O2 evolution generally was inhibited at low water potentials (psiw) but more in sunflower leaves than in Fucus fronds at the same psiw. As psiw decreased, less carbon accumulated in an organic carbon store in F...

Orobanche cumana is a holoparasitic plant naturally distributed from central Asia to south-eastern Europe, where it parasitizes wild Asteraceae species. It is also an important parasitic weed of sunflower crops. The objective of this research was to investigate genetic diversity, population structure, and virulence on sunflower of O. cumana populations parasitizing wild plants in eastern Bulgar...
