Abstract
The present paper deals with methodology, criteria, and directions of the investigation in genetic specificity of plant mineral nutrition. The genetic specificity is found in a great number of plant species such as maize, wheat, soyabean, apple, sugarbeet, grape, etc. The content and concentration of elements in genotypes of the same plant species vary greatly. These variations are affected by growth conditions of plants as well as their developmental stages. Therefore, they may be established in the same growth conditions and at the same developmental stages only. Also, genetic specificity in plant mineral nutrition may be affected by certain physiological and biochemical processes. Genetic specificity in plant mineral nutrition is manifested not only through the element content of certain plant organs but in the morphological and physiological features and in plant dry matter weight.
