Weed Control of Cuscuta by Silver Nanoparticle Phytosynthesis Extract of Rhazya stricta Plant

چکیده مقاله

The study of Weed control of Cuscuta by silver nanoparticle photosynthesis extract of Rhazya stricta plant was conducted in two separate experiments as a completely randomized design in three replications in the Medicinal and Ornamental Plants Research Center of Sistan and Balochistan in 2022. The results of synthesizing these nanoparticles showed that the nanoparticles had a maximum absorption at a wavelength of 400-415 nm, an average size of 10-12 nm, and a spherical and uniform shape. The results of the effects of nanoparticle extracts on the germination and growth of Cuscuta weeds showed that 100% silver nanoparticle extract of R. strictasignificantly decreased the germination percentage (50.66%), germination vigour (10.50) and germination rate (2.03) comparison with other treatments. The mean germination time was 2 days in control and increased to 4 days after applying 100% silver nanoparticle extract of R. stricta. Besides, rootlet length and plantlet length were affected by R. stricta extracts. The most reduction was related to 100% silver nanoparticle extract with 0.40 cm in rootlet length and 0.50 cm in plantlet length.
