Watermelon nuts is widely cultivated in Khorasan Razavi for its edible seed production. Two experiments were therefore, conducted to increase seed production in Bahonar University of Kerman Research Station in 2013 and 2014. In first year, the effects of gibberellic acid (0 and 50 mg/l) and fruit number (1, 2 and 3 fruits /plant) were studied in 4 populations. In second year, the effects of 24-...

Female and male rats weighing about 170 g and 200 g, respectively, were fed diets (approximately 70 microg boron/kg) in a factorial arrangement with supplemental boron at 0 (deficient) and 3 (adequate) mg/kg and canola oil or palm oil at 75 g/kg of diet as variables. After 5 weeks, six females in each treatment were bred. Dams and pups continued on their respective dietary treatments through ge...

plants uptake boron (b) from the soil solution, in which boron concentration is controlled by adsorption and desorption reactions on soil organic and inorganic colloids. considering the importance of aluminosilicate minerals in ion adsorption and desorption reactions in soil, in this research, b adsorption behavior on kaolinite was studied as a function of equilibrium concentration, ph, kaolini...

In this study, Boron carbide was synthesized using Mesoporous Carbon CMK-1, Boron oxide, and magnesiothermic reduction process. The Effects of temperature and magnesium grain size on the formation of boron carbide were studied using nano composite precurser containg mesoporous carbon. Samples were leached in 2M Hydrochloric acid to separate Mg, MgO and magnesium-borat phases. SEM, XRD and Xray ...

Abstract: Soybean has shown increasing performance in terms of yield recent years. However, despite this growth, the lack quality control and knowledge about effects nutritional status plants compromised germination vigor a significant proportion seeds. The aim study was to evaluate physiological seeds root growth soybean cultivated with boron (B) sources different solubilities incorporated int...

Two experiments were conducted with weanling Sprague-Dawley rats to determine whether changes in S-adenosylmethionine utilization or metabolism contribute to the diverse responses to boron deprivation. In both experiments, four treatment groups of 15 male rats were fed ground corn-casein based diets that contained an average of 0.05 mg (experiment 1) or 0.15 mg (experiment 2) boron/kg. In exper...
