The role of allelopathically active substances in intergenotypical interrelations of spring wheat and rye in combined agrophytocenoses

摘要

The results of studying allelopathically active excretions of different species of spring wheat and rye and their role in intergenotypical interrelations of these crops in artificially formed agrophytocenoses are given. It is shown that allelopathically active rye exomethabolits change methabolism of wheat plants, hamper their growth and cause their chromosome destruction. Mutagenic activity of allelopathically active excretions cause increase in crossing of wheat and rye.
