Abstract

Amaranthus spinosus L. weed grows luxuriantly in unpolluted fallow land, along roadsides and in areas contaminated with sewage water. Laboratory studies proved its phytotoxicity to redgram and fenugreek. The concentration of the allelochemicals was maximum in the leaves and least in the roots. Interestingly, the plants collected from the unpolluted area, roadside with heavy vehicular traffic and along the sewage line differed in phytotoxicity. However, detailed phytochemical analysis failed to show any qualitative difference, though there was quantitative difference in the allelochemicals. The nature of the allelochemicals and the effect of pollutants on the allelopathic potential of Amaranthus spinosus L. are discussed in the paper.
