Abstract The wide use of copper (Cu)-based fungicide has caused a stepwise accumulation Cu in the environment increasing occurrence phytotoxicity crops. To understand and alleviate this abiotic stress, maize seedlings were grown hydroponic solution with different combinations iron (Fe) forms. Results showed that sensitivity is related to nature form supplied chelate-exchange processes might inv...

Iron (Fe) deficiency chlorosis (IDC) affects the growth of several crops, especially when growing in alkaline soils. The application synthetic Fe-chelates is one most commonly used strategies IDC amendment, despite their associated negative environmental impacts. In a previous work, Fe-chelate tris(3-hydroxy-1-(H)-2-methyl-4-pyridinonate) iron(III) [Fe(mpp)3] has shown great potential for allev...

in order to evaluate of biological fertilizers and micronutrient elements effects on yield and some agronomic traits in rapeseed (brassica napus l.), an experimental was performed as factorial arrengement based on randomized complete blocks design with three replications in 2012-13 in research station of shahid chamran university of ahvaz, iran. in this experiment, micronutrient elements were i...

The increase in the cost of fertilizers and their low efficiency has led, through nanotechnology, to generation new innovative products that are sustainable improve productivity crops. Therefore, objective present study was evaluate efficacy a molybdenum nanofertilizer compared two conventional (chelate sodium molybdate) applied via foliar combined with soil fertilization NH4NO3 relation Nitrog...

sis usually involve chaotropic agents such as guanidinium chloride and (or) detergents for the dissociation of iron at an acidic pH from transferrin. Reduction is achieved with various reducing compounds such as ascorbic acid, hydroxylamine, thioglycolic acid, and others. Among these, ascorbic acid is unique in its property not only to reduce but also to chelate iron. This property appears to b...
