The allelopathic characteristic of some Alnus Mill. genus species

Abstract

Data about allelopathic activity of certain species Alnus Mill. is presented. It has been found that alder’s water-soluble compounds show different allelopathic activity depending on species, studied organ, test-object and concentration of active compound. Amaranth and wheat roots appeared to be the most sensitive to the alder allelopatically active substances than coleoptile. The leaves’ activities were higher than those one of stems and roots. The immature plants showed more difference in allelopathic potential than mature plants.
