Abstract

Root structure indicates the ability of Heracleum sosnowskyi to absorb resources quickly under optimum soil conditions.

Abstract

The structure of the root systems and roots of the invasive plant Heracleum sosnowskyi and the local species H. sibiricum have been compared in three habitats of the southern taiga subzone by the standard methods of plant morphology and anatomy. Differences in the structure of the root systems and roots of H. sosnowskyi and H. sibiricum ensuring the ability of the invasive species to absorb resources under optimum soil conditions have been revealed. These are the occurrence frequency of ephemeral roots, the number of orders of root branching, the size of absorbing roots, and the development of xylem elements.
