摘要：This paper presents a research on the content of low-molecular
metabolites possessing protecting properties (free proline, reducing sugars,
succinic acid) in Taraxacum officinale Wigg. which grows on the mining
wastes of Kedrovsky open pit in Kemerovo region. The paper also
researches the topic of relation between the content of the above substances
and morphometric characteristics of the plant such as weight of leaves and
roots, length of roots and surface area of leaves. In the course of the
research in was established that adverse edaphic effects of mining waste
cause adaptive changes of Taraxacum, which affect the plant on
biochemical and organ level. As for biochemical level the increase in
content of low-molecular protectors in leaves and roots was revealed. As
for organ level the evident reduction of morphometric characteristics
(weight of leaves and roots, length of root, surface area of leaf) was
revealed which can be interpreted as an evidence of xerophytesation
increasing the plant’s survivability in hostile environment. The revealed
adaptive changes described above form the plant’s resistance to the
extreme environmental factors and present an evidence of plant’s ability to
fully conduct its vital functions in the conditions of the mining waste.
