most seeds of medicinal plants due to ecological adaptation to environmental conditions have several types of dormancy. hence, it's necessary to recognize ecological factors that affect dormancy and provide optimum conditions for germination in medicinal plant species. thirty seed lots were used to estimate germination and dormancy of medicinal plants. treatments were kno3, (2%) and scarificati...

using the evaporating method, the solubility of potassium nitrate was determined in various mixtures containing water and ethanol at 25°c. the results show that the solubility of kno3 decreases with increasing the mass percent of ethanol in the mixtures. this trend is along with decreasing the dielectric constant of water+ethanol mixtures. moreover, it can be concluded that the totqal solubilit...

Dead spot is a relatively new disease of creeping bentgrass (Agrostis stolonifera L.) incited by Ophiosphaerella agrostis Dernoeden, M.P.S. Câmara N.R. O’Neill van Berkum et M.E. Palm. Limited information is available with regards to chemical and cultural management strategies for dead spot. Two field studies were designed to evaluate the influence of various fertilizers and iprodione on the re...

Ingestion of dietary (inorganic) nitrate elevates circulating and tissue levels of nitrite via bioconversion in the entero-salivary circulation. In addition, nitrite is a potent vasodilator in humans, an effect thought to underlie the blood pressure–lowering effects of dietary nitrate (in the form of beetroot juice) ingestion. Whether inorganic nitrate underlies these effects and whether the ef...
