摘要

Herbicidal effects of aqueous leaf extracts of three?Chenopodium?species;Chenopodium album?L., Chenopodium murale?L. and?Chenopodium ambrosioideswere evaluated on wild oat (Avena fatua?L.), one of the problematic weeds of wheat. Among?the?aqueous extracts of 0, 2, 4 and 6% (w/v) employed in bioassays, 6% ofC. album?and 2% of?C. murale?caused significant inhibition in germination of?A. fatua?resulting in 66 and 34% decline in germination, respectively. Lower concentration of 2% of all the three?Chenopodium?species enhanced seedling growth of?A. fatua.?The?highest extract concentration of?C. album?(6%) markedly suppressed both length and biomass of shoot of test weed species. The highest herbicidal effect was exhibited by 6%?C. album?leaf extract, resulting in 88, 89, 70 and 92% reduction in maximum and total root length, number of roots and root biomass, respectively. This??study concludes that the aqueous leaf extracts of?C. album?contain herbicidal constituents for the management of?A. fatua.
