The effect of trampled soil on the biomass allocation of Ambrosia trifida
MetadataShow full item record
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.
