| description | The aim of the current research is to evaluate the allelopathic activity of fifty grass genotypes from different species and to identify phenolic compounds in the genotypes that have the highest allelopathic activity and inhibitory effect on <i>Eruca sativa</i> L. (Rocket). Aqueous extract was prepared from the leaves of grass genotypes in different concentrations and its effect on germination and growth of <i>E. sativa</i> L. was measured. According to the results, the type of genotype and the concentration of the extract significantly decreased the percentage of germination, hypocotyl length, radicle length, and dry weight of <i>E. sativa</i> L. seedlings. Increasing the concentration of the extract resulted in a decrease in germination and growth of seedlings. The genotypes of <i>Festulolium</i> (Festulolium) (GR 5009, GR 1692, GR 5004) had the most inhibitory effect on the growth of <i>E. sativa</i> L. Also, among the genotypes studied, two genotypes (DG-M) and (DG-P) of <i>Dactylis glomerata</i> L. (orchardgrass) species showed the least allelopathic activity. The results of HPLC-MS indicated nine phenolic compounds including caffeic acid, syringic acid, vanillic acid, p-coumaric acid, ferulic acid, apigenin acid, chlorogenic acid, 4-hydroxybenzoic acid, and gallic acid. The phenolic compound most present in the aqueous extract was caffeic acid. However, phenolic compounds derived from <i>Festulolium</i> genotypes showed the greatest allelopathic action on the growth parameters of <i>E. sativa</i> L. The aqueous extracts of the <i>Festulolium</i> genotypes can be considered valid systems of sustainable weed control thanks to the phytocomplex rich in phenols. |
