Efecto alelopatico de Sorghum halepense (L.) Pers. sobre el crecimiento de la plantula y la biomasa aerea y radical de Triticum aestivum (L.)


, : Efecto alelopatico de Sorghum halepense (L.) Pers. sobre el crecimiento de la plantula y la biomasa aerea y radical de Triticum aestivum (L.). Ecologia Austral 13(1): 49-61

Allelopathic effects of four Sorghum halepense populations on both seedling growth and above-ground and below-ground biomass of wheat (Triticum aestivum) varieties after 50 and 90 days of soil decomposition were studied. Weed rhizomes from four Argentinean sites (Rufino, Rojas, Parana, and 9 de Julio) were collected. Aqueous extracts of the rhizome residues were tested for phytotoxicity to radicle growth and coleoptile growth of four early wheat varieties and four late wheat varieties.
