Abstract

The effects of aqueous extracts from aboveground parts ofSolidago canadensisL. 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 ofLepidium sativumseeds were investigated. It was showed thatSolidago canadensisandFilipendula ulmariahave the greatest effect on the reduction of germinating capacity ofLepidium sativumseeds.

Highlights

According to a number of scientific reports, Solidago canadensis can suppress the development of many herbs on the different stages of ontogenesis [1 – 5] leading to the dysfunction of native phytocenosis and failure of disturbed land restoration caused by S. canadensis invasion beyond their native areal (North America) [6 – 10].To study the effects of Solidago canadensis L. on the germinating capacity of other plants’ seeds and to compare the obtained effects with ones of dominant species of four main succession stages on the degraded forest soils of the Kemerovo region (Filipendula ulmaria, Chamaenerion angustifolium, Cirsium setosum, Poa pratensis) we selected Lepidium sativum L. characterized by the most balanced differentiating ability in assessing the allelopathic activity of various “donor plants” [11]
The germination capacity and speed (19% on the first day of the experiment and about 70% in total) was discovered in the control group; the extracts obtained from all studying herbs at the first stage of the experiment were associated with significantly reduced germination (Fig. 1)
The majority of studied extracts lose their effects after third day of the experiment – the viability of seeds of testing culture approach the control values excluding the extracts obtained from Solidago canadensis and Filipendula ulmaria associated with the suppressed development of testing culture
