| Abstract: | Gametophytic development and rapid-proliferation techniques of Lygodium scandens (Linn.) Sw. were studied. The process of spore germination and gametophytic development were observed and recorded. The spores were gold, blunt triangular polar view, the equator concept as a semi-circular or circular and three cracks. The pattern of spore germination was the Anemia-type and the gametophyte development was the Adiantum-type. Lygodium scandens(Linn.) Sw. was cultured with tissue culture for rapid propagation, an... |
