Study of influence of adentitious sorts of drug plants on agrophytocenosis

Abstract

The purpose. Support or resistance or agroeco· systems, safe enrichment of biodiversity. Methods. Classical. oomparative. morphological·eoological·ge· ographycal. Results. The sorts which h.ave justified in new terrain, often appear too aggressive and drive out plants peculiar to that area. To such adcntitious sorts we may treat Potygonum cuspidatum and Potygonum sachalinensis. For searching altemative sources naver noids we use sorts or family of Polygonum which can be used as raw material for biologically ae!ive drugs. Conclusions. At use for production of adcntitious and invasion hazardous sorts one should simultaneously monitor their numerosity in places of their significant spread.
