Response of biotesterLepidium sativumto the effects of native herb extracts and phytoinvaderSolidago canadensis

Abstract

The effects of aqueous extracts from aboveground parts of Solidago canadensis L. as well as from dominant species of four main succession stages on the degraded forest soils of the Kemerovo region (Filipendula ulmaria, Chamaenerion angustifolium, Cirsium setosum, Poa pratensis) on the germinating capacity and speed of Lepidium sativum seeds were investigated. It was showed that Solidago canadensis and Filipendula ulmaria have the greatest effect on the reduction of germinating capacity of Lepidium sativum seeds.
