Roth, Dryopteris filixmas (L.) Schott and D. affinis (Lowe) Fraser-Jenk. In order to reach this issue, we proposed the following objectives: the monitoring of the gametophyte differentiation on the soil that was contaminated with different lead concentrations and the estimation of the physiological status of the 3 species of fern in the initial development status (gametophyte and young sporophyte) through the analysis of the photosynthetic pigments and the determination of the antioxidant potential through the analysis of polyphenols. The variants tested were V1=0.1 g Pb, V2=0.2 g Pb, V3=0.5 g Pb, V4=1 g Pband Control. Of the three species considered in the study, we have noticed, for the Athyrium filix-femina, the most advanced differentiation of the gametophyte. Low Pb concentrations: V1 and V2 stimulate the pigments content at A. filix-femina, respectively at Dryopteris filix-ma...
