In order to evaluate the effect of urban wastewater and different fertilizer sources on macro and micro nutrients' concentration and shoot dry weight of sugar beet, a field experiment was arranged as a split plot in RCBD design with three replications at Research Station of Shahrekord University in 2013. The main factors included irrigation with urban wastewater at 2-4 leaf stage and 8-12 leaf ...

Madagascar periwinkle is one of the important medicinal plants belonging to Apocynaceae family. In this study the effects of nano zinc oxide on growth index wet and dry weight, leaf surface, photosynthetic pigments, total carbohydrates and amount of elements were investigated. Experiments were designed completely randomized in greenhouse culture conditions with three replications. Zinc oxide na...

The genetic and nongenetic factors affecting the elemental composition of animal and human tissues are presented. Genetic factors include: (1) some well-known inherited diseases that affect copper, zinc, iron, magnesium, manganese and selenium metabolism; (2) animal species differences and (3) breed differences within animal species. The nongenetic factors include regional variation, dietary co...
