Selected features of Canadian goldenrod that predispose the plant to phytoremediation

Abstract

Solidago canadensis (Canadian goldenrod) is an invasive plant species occurring in Poland. Canadian goldenrod tolerates a wide range of habitat conditions, it grows in landfills and soils contaminated with heavy metals. The paper presents the selected biometric features of the plant which indicate the possibility of its use for phytoremediation purposes. The analysis was based on the results of own research and literature data. The biometric features of the plant chose for the research are: aboveground biomass (which reaches about 4.4 tons d. m/ha on a surface covered with the plant in more than 70%), the possibility of annual collection of the aboveground parts and their use for energy purposes, extensive roots and rhizomes system ensuring soil stabilization, high accumulation of some metals in the underground parts of the plant.
