ABSTRACT: Horsetail (Equisetum arvense L.) is a perennial
herb which creates during the life cycle spring and summer stems. The selected
species and populations were monitored in the years 2009-2011
in three
different natural locations in Laborecká vrchovina (Slovakia).
Samples were collected by destructive methods in all three locations. Silicon
content was determined in dry biomass by AAS. Silicon content in plants ranged
from 21.11 ± 3.24 g·kg-1 to 32.80 ± 8.03 g·kg-1. The highest content of silicon
exhibited samples of the September collection. We found that the location and
the year in terms of silicon content were not statistically significant. The
main sources for statistical variability in the accumulation of silicon were
during the collections.
