Allelopathic activity of Acer negundo L. leaf litter as a vector of invasion species into plant communities

Abstract

The article shows the results of the influence of different concentrations of allelochemicals of Acer negundo L. leaf litter, germination energy, absolute germination of seeds and plant growth. The seeds of Raphanus sativus L. and Avena sativa L. were used as model objects. Active substances contained in leaf litter A. negundo, have a selective inhibitory effect on the germination of seeds and the growth of seedlings of monocotyledonous and dicotyledonous plants. The allelopathic effect of the fall is not a limiting factor for the germination of seeds of herbaceous plants of the above-ground cover of the studied plantation.
