Abstract
Ambrosia trifida is an invasive
species that is believed to have first arrived in
Korea with the American troop deployment
during the Korean War and has since taken root
in the ecosystem. Ambrosia trifida is most
commonly found in military or developmental
areas where there is a high level of human
activity. Since trampled soil is a result of human
activity, this study was conducted with the aim of
analyzing the growth process of Ambrosia trifida
in trampled soil by examining biomass allocation.
Biomass allocation indicates how the plant
optimizes resources by distributing nutrients to
different parts of the plant. By measuring the
number of leaves, stem length, stem thickness,
and root growth of Ambrosia trifida, this study
found that plants in the control group allocated
more resources to their leaves. On the contrary,
plants in trampled soil allocated more resources
to their roots. There were no significant
differences between the control group and the treatment group in stem length, stem thickness,
and the number of leaves.
