Canada Goldenrod Solidago canadensis L.

Abstract

The Canada goldenrod Solidago canadensis L. is a rhizomatous, patch-forming herbaceous perennial plant in the family Asteraceae. It was introduced into China in 1935. In addition to its prolific vegetative propagation, S. canadensis releases chemicals that inhibit the growth, germination and survival of native plants, and change the soil composition by diverting nutrients and minerals. Soil water content has greatly influenced the growth of this invasive plant. It is currently abundant in four provinces of southeastern China, with scattered populations in other provinces. The latitudes of the potential range span from 25 degrees to 50 degrees. S. canadensis has caused great ecological threat to biodiversity. Chemical control, mechanical eradication and biological control are possible strategies for management of this invasive plant. Besides, S. canadensis contains a wide range of bioactive compounds that are responsible for its antioxidant, antimicrobial, anti-inflammatory and spasmolytic and diuretic properties.
