Abstract: (6 Views)
The increasing use of chemical inputs and their environmental consequences have led to the creation of strategies for targeted control of weeds, including the synthesis of nanoparticles with plant extracts. An experiment was conducted as a factorial experiment based on a completely randomized design with three replications at Mohaghegh Ardabili University in the spring of 2024. The treatments included Sunflower aqueous extract (0, 30, and 60 g L-1), titanium dioxide nanoparticles synthesized with sunflower aqueous extract at 30 and 60 g L-1, titanium dioxide nanoparticles synthesized without extract and control. Titanium dioxide nanoparticles were synthesized by the sol-gel method for 48 hours, and the type of bonds was identified using FTIR. Germinated wild mustard (Sinapis arvensis L.) seed counting continued for 14 days, and at the end, seedling length and weight indices were measured. The results showed that seed germination decreased 25 and 50% and dry weight decreased 21.49 and 53.48% in 30 and 60 g L-1 of sunflower aqueous extract by titanium dioxide nanoparticles compared to sunflower aqueous extract. The minimum radicle and plumule length (1.20, 0.93, 1.90, and 1.33 cm) and catalase enzyme activity (55.46 OD μg protein/min-1) were obtained from 60 g L-1 in both treatments. The increase of lipid peroxidation in nanoparticles synthesized with 30 and 60 g L-1 of extract was more (10.71 and 3.65 %) than that of aqueous sunflower extract. The results showed high inhibition of titanium dioxide nanoparticles synthesized with sunflower extract on germination and length and weight indices of wild mustard seedlings.
