- Abstract
Setaria pumila (SP) and latuca sativa are the prominent teff (Eragrostis tef) weeds negatively impacting yield. The allelopathic (weed-suppressing) effects of ten teff varieties were examined for plant growth inhibitory effects, as well as for antagonism against certain major plant infections caused by bacteria and their subsequent antioxidant properties. The in vitro germination and antimicrobial assays were carried out in controlled laboratory settings. The teff cultivar DZ-Cr-387 suppressed weed germination and had substantial allelopathic potential. Both teff shoot and root extracts were noted to have an allelopathic influence on experimental seed germination in comparison to the control. Observations were made on the germination percentage, rate of germination, and germination duration. Additionally, extracts from teff shoots and roots showed significant free radical scavenging activity. Reactive oxygen species, or ROS, have been demonstrated to operate as both signalling compounds and harmful molecules that can oxidatively affect plant tissues throughout all stages of their lifecycle. The highest level of inhibition was reported in DZ-Cr-387 and DZ-01-1681, with a free radical scavenging potential of 85 percentage. The allelopathic teff varieties were also clustered together, indicating that these teff varieties have the potential for allelopathic and anti-microbial capabilities. These allelopathic chemicals can be employed as part of eco-friendly weed management strategies, to generate antimicrobial compositions to combat plant diseases for sustainable agriculture and for use in organic farming. Utilizing these teff varieties will benefit organic farmers by lowering their reliance on chemical inputs in traditional farming systems., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.
