Abstract

The results show the effect of water extracts from dry biomass of adventive plant species with high invasive activity from Belarus on the growth of seedlings of test plants. High correlation between the effect of biologically active substances released from the seeds of Heracleum sosnowskyi Manden on various test plants and plant species is discussed. The strong stimulating effect of water extracts on plant species from Cruciferae family is shown. Plant species from Poaceae family are mainly characterized by a neutral reaction to the biologically active substances emitted from H. sosnowskyi seeds. It has been found that water extracts at the concentrations from 0.01 to 0.001 % have a stimulatory effect on the growth and development of test plants, while an inhibitory effect was observed at the concentrations in the range from 1 to 10 %.
