Abstract

Allelopathy can play an important role in control weeds. Achillea L. is a plant with allelophatic activity. By considering abundance of Achillea species in Iran, a laboratory experiment in 2013-2014 in Isfahan University of Technology was implemented. In this experiments aqueous extract from two Achillea species collected from different region of Iran, including A. nobilis (khorasan), A. pachycephala (Golestan) and A. pachycephala (Hamadan) on Amaranthus retroflexus at concentrations of 0, 3, 6, 12, 25, 50 and 100 percent was performed. The results showed that various concentrations of aquous extract have different effects on target species and their characteristics. Genotype of A. pachysephala of Hamedan has stronger Allelopathy effect and genotype of Golestan has the lowest one. Extracts in concentrations between 3 to 12% have a stimulatory effect and in concentrations of 25 to 100% showed inhibitory effect.
