Versions Notes

The aim of this study was to establish the influence of ferns extracts (Asplenium scolopendrium and Dryopteris filix-mas) on spore germination and gametophyte development in two Dryopteris species.
The extracts were obtained from Asplenium scolopendrium (EA) and Dryopteris filix-mas (ED) leaves. Some variants contained, beside the extracts, Ag nanoparticles (EAN, EDN) [1,2]. Variants with alcohol were also tested (HA). For each variant, dilutions were made (1:10, 1:100).
The percentage of germinated spores decreased after extracts exposure (Figure 1 and Figure 2). In variants with AgNPs, no germination was observed regardless of extract, dilution or species. In the variants with alcohol, the germination of spores was significantly inhibited compared with the control (C, Figure 3) at the smallest dilution, in both species (Figure 4). The lack of the spore’s rhizoid affected the gametophyte development (Figure 5).
Overall, the ferns extracts had a negative influence on ferns spores by reducing the germination percentage and by inhibiting gametophyte development in both species.
