Abstract

Parthenium is widely distributed, almost across the world and has become the most important invasive weed. The present study was designed to investigate the allelopathic effect of aqueous extracts of Anagallis arvensis L. against the Parthenium hysterophorus L. A. arvensis extracts demonstrated inhibitory effects on seed germination and seedling growth of parthenium. Aqueous extract of leaves and inflorescence of A. arvensis exhibited highest inhibition than the extracts of root and stem. Significant control was calculated in germination percentage (50%), fresh weight of seedling (-55% and -44%) and dry weight of seedling (-65% and -66%) by aqueous leaves and inflorescence extracts of scarlet pimpernel. In vitro foliar bioassay aqueous concentration (15 %) of A. arvensis surpasses the all treatments and reduce the fresh biomass of plant (-45%) and dry biomass of plant (-42%) in first week of spray and fresh biomass of plant (-75%) and dry biomass of plant (-82%) in second week of spray. Under In vivo conditions, significant reduction was calculated in fresh and dry biomass of root and shoot of Parthenium hysterophorus in response to allelopathic stress of dried whole plant of Anagallis arvensis. Parthenium fresh root biomass reduced from (-10% to -39%) and dried root biomass reduced from (-20 to -40) respectively as compare to control. Parthenium shoot fresh biomass reduced from (-25% and -26%) and dried biomass of shoot (-26% and -17%) respectively as compare to control.
