In this study, we aimed to establish the influence of aqueous ferns extracts on the growth in length of the cucumber root. There were tested variants with aqueous extracts obtained from leaves of two species of ferns: Asplenium scolopendrium L. (As) and Dryopteris filix-mas (L.) Schott (Dfm). Some variants with aqueous extracts also contained Ag nanoparticles (As NP, Dfm NP). In this experiment, we used two dilutions (1:10, 1:100) for each type of extract.
At the first (Figure 1—left) and the second (Figure 1—right) measurements, the highest values of root length were obtained at the variants with AgNPs regardless of dilution. After 5 days of exposure, the highest average root length was 42.73 mm and settled at As NP 1:100 variant (Figure 2—left). Generally, for the variants without nanoparticles, better results were recorded at 1:10 dilution (Figure 2—right) than at 1:100 dilution. AgNPs have a positive effect at low concentrations [1]. Cui et al. (2014) observed that cucumber root elongation was stimulated after exposure to AgNPs at concentrations below 200 mg L−1 [2].
During the experiment, all extracts stimulated the growth of the root length in C. sativus compared to the control.
