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

Abstract

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