Tragus racemosus often grows in close proximity to motorways. The aim of this work was determine whether the seeds species can grow under salt (NaCl) stress, how plants are able accumulate heavy metals and what plant architecture prerequisites they have for spreading. It found that structure consists a single rosette first order, from which shoots order develop, on rosettes second grow, is repeated modularly. Higher-order produce their own root systems. Research revealed its small metal tolerances during germination early development. concentration above-ground parts following rank: Fe >> Zn > Ni ≥ Pb Cu; soil, it Cu Ni. germinates successfully environments containing NaCl up 0.50% (including solutions 0.12% 0.25%). However, higher contents 0.99% 1.96% proved lethal seed germination. This tolerance explains why T. commonly along motorways where winter road maintenance involves application salt. These adaptations give competitive advantage these human-modified environments. Furthermore, turned out be possible hyperaccumulator.
