The article gives an analysis of the elemental
composition in raw materials of stevia. Stevia plant is
able to regulate the flow of heavy metals, allowing
them, on the one hand, actively oppose the excessive
intake of toxic elements and on the other hand,
selectively cumulate essential elements. The contents
of essential elements in plant raw materials do not
exceed the acceptable standards regardless of the
growing conditions
A priority direction at the present stage of vegetable
growing development is to obtain high-quality,
environmentally friendly production on the basis of
development and introduction of new technologies of
cultivation. At the same time, it is compulsory to
emphasize the importance of expanding the range of
crops which can vary nutrition of population. Currently
promising direction is search of new high-efficient and
environmentally friendly methods of plant protection.
Biological methods of effect on the plant body acquire
great significance. One of such methods is using grafts.
In a light of new changed conditions, the research on
grafted plants was not conducted in our country
The analysis of the accumulation and distribution of
heavy metals in the stevia raw material grown in
different agroecological regions is carried out. The
elements present in the soils always have a complex
effect on the plant and at the same time enhance or
weaken each other's action. Plants of stevia are able to
regulate the flow of the heavy metals under study,
assimilating organs accumulate the optimal number of
elements necessary for their growth and development,
regardless of the growing conditions
