Germination and growth of Deschampsia cespitosa and Festuca ovina in arsenic soil
Arsenic contaminated soil is one of the major arsenic sources for potential harmful ecological impact on living organisms. Phytoremediation using viable plant species is an emerging, biological technology for the removal of toxic contaminants from soil. Although hyperaccumulating plants and plant va...

Arsenic contaminated soil is one of the major arsenic sources for potential harmful ecological impact on living organisms. Phytoremediation using viable plant species is an emerging, biological technology for the removal of toxic contaminants from soil. Although hyperaccumulating plants and plant varieties are known, there is still a need to find new (and preferably local) plant species for phytoremediation. The aim of this study was to investigate the germination and growth of two grass species common in the northern Fennoscandia with respect to the influences of high concentration arsenic. The study was conducted on Deschampsia cespitosa and Festuca ovina species that were collected from both arsenic contaminated and arsenic free areas at Green Stone Belt area in Kittilä, Central Lapland. Seed germination, seedling growth and cuttings growth in both the arsenic contaminated soil (collected from Kuotko area) and controlled soil (collected from Kallo area) were observed over a period of 8 weeks (2017 to 2018). Seed or cutting origin, soil type and inoculant plant origin, all either contaminated (arsenic) or control, were the studied factors.
