As a scientific discipline, plant nutrition stands on two legs. One leg is anchored in plant physiology and explains the fundamental processes underlying and regulating the acquisition, allocation, and utilization of mineral elements in plants. The other leg is deeply rooted in an applied, problem oriented context, explaining the use and action of fertilizers and the cycling of mineral elements...

Background: The quality and quantity of the diet has undeniable effects on the reproduction of organisms. We examined the effects of two diets (with and without mineral supplementation-Vitamins) on super-ovulation in two strains of mice (B6D2F1 and NMRI) in Royan Institute, Tehran. Materials and Methods: For this purpose, 40 female mice (21 days) from each strain were divided into four experime...

Recent research has discovered childhood mental retardation is related to the presence in the body of above-normal levels of certain mineral elements, especially lead and cadmium. This study investigated the relationships between mineral elements and mild and borderline mental retardation and determined which minerals, if any, separated a group of mentally retarded children from a nonretarded c...

Many publications describe cryopreservation techniques but only a few studies have focused on the biochemical and physiological changes occurring in plants regenerated from seeds exposed to liquid nitrogen. This paper aims at describing the effect of common bean seed cryostorage on mineral nutrition of young plantlets. The following elements were measured on leaves of 10-dayold plantlets from n...
