Gametophytic responses of Pityrogramma calomelanos to Pb(II) stress: potential application in water pollution assessment.
Environmental contamination by heavy metals is a global issue, requiring effective and long-lasting remediation techniques. Pteridophytes are vascular plants that show phytoremediation potential in both gametophytic and sporophytic phases. Pityrogramma calomelanos (L.) of the family Pteridaceae is a fast-growing fern t...
