to evaluate the effect of growth promoting bacteria on morphophysiologic traits and nutrient uptakes of two rice cultivars, an experiment was carried out in 2009-2010 cropping season in rice researches institute of rasht. the experiment design consisted of four randomized complete blocks in a factorial arrangement having 16 treatments in 4 replications. in this research, two factors were evalua...

Alginate-metal complexes were prepared with divalent (Ca, Ba, Zn) and trivalent metals (Fe, Al) via congealing method in form of beads. Alginate mixed metals (Ca & Fe) complexes were also prepared by simultaneous and consecutive congealing. The studied beads were blank beads and racemic ketoprofen (KTP) loaded beads. Metal content was determined by atomic absorption spectroscopy and was 1.8% to...

Iron (Fe) is an essential element for human nutrition, and its deficiency or low hemoglobin levels are a global health issue. Strategies aimed at increasing the amounts of essential elementals in agricultural products, as sprouts of adzuki bean (Vigna angularis), can be a way to minimize deficiencies, mainly in the populations of developing countries. Therefore, in this work was evaluated: prod...

Aluminum and silicon are usually abundant in the soil and most plants are affected by them. Therefore, in the present study, the effect of the interaction of Si (0 and 2 mM) and low concentrations of Al (0, 50, 100, and 150 µM) on some physiological parameters of Zea mays var. Merit were investigated and were analyzed by cluster heatmaps for better interpretation of results. Results showed that...

Sunflower plants were grown on soil contaminated with several levels of Cd (from 0.3 to 15 mg Cd kg/soil). Cd and nutrient (Cu, Zn, Fe, Ca, K, Mg) contents were evaluated in root and aboveground biomass during the vegetative growth period (from the emergence of the cotyledon leaves to the flower bud phase). An overall increase of Cd content was found in the plants during the growing cycle. Sign...
