Features of the accumulation of heavy metals by different genotypes of spring wheat under conditions of soil contamination with copper and lead

At present, the human impact on the biosphere is global in nature, connection with which issues of environmental pollution by many toxic substances, including heavy metals, have become very urgent. The long period of self-cleaning contaminated soils and high cost their technogenic cleaning make mankind look for new ways to solve this problem. The identification of plant objects characterized a minimal accumulation heavy metals is most promising direction area. The aim of our study determine tolerance wheat genotypes severe metals, priority East Kazakhstan region, as well donors for breeding for metal resistance and forms wheat. The object research work of spring wheat from collection Research Institute Agriculture: GVK (East genotype) -11/14, GVK-19056, GVK-19055, GVK-19012, GVK-19009.
