Abstract:

The development of nanotechnologies represents a promising way to improve sustainable agriculture because nanoparticles can be used as fertilizers, fungicides, herbicides, insecticides, can reduce the stress caused by various factors (salinity) or can be used for seed priming. Green synthesis is an important method to produce nanoparticles due to the lack of toxic waste and because is relatively simple and cheap. However, nanoparticles have unique properties that influence their bioavailability, bioaccumulation and toxicity. Because of this ecotoxicological research, which studies the effect of nanoparticles on plants are important. In this study, we determined the effect of spore extracts with green synthesized bimetallic nanoparticles on cucumber. For obtaining the extracts, we used spores from two species of ferns (Asplenium scolopendrium and Dryopteris filix-mas) and two types of solvents (water and hydroalcoholic solution). The bimetallic nanoparticles (Au:Ag 1:1 and Au:Ag 1:10) were synthesized using HAuCl4 and AgNO3. The extracts were tested in Cucumis sativus seeds after being diluted 10 and 100 times, respectively. Exposure of Cucumis sativus seeds to aqueous extracts of A. scolopendrium and D. filix-mas spores with and without bimetallic nanoparticles has usually stimulated root growth, while the stem growth was stimulated only at the variants without bimetallic nanoparticles. For the hydroalcoholic extracts, at the variants with extracts with bimetallic nanoparticles diluted 100 times were obtained better results than in control with water or with hydroalcoholic solutions.
