| The most effective conditions of In vitro culture and ex vitro sporophyte formation from prothallus were studied for mass propagation of Dyropteris varia. The most effective medium of prothallus proliferation was Murashige and Skoog's basal medium supplemented with 10:50mM of $NH_4^+:NO_3^-$ and 2% sucrose. The optimum pH level was 5.8 and prothallus growth was promoted on medium containing $0.6{sim}0.8%$ agar. Almost of the tested growth regulators (NAA, IAA, 2,4-D, BAP, kinetin and 2ip) were inhibitory in prothallus proliferation as the concentration of growth regulators became higher. The highest number of sporophytes was obtained by transplanting prothallus on compost only than on any other soil compositions. Sporophyte formation was promoted remarkably by soaking prothallus with $100{mu}M;GA_3$ for 3 hours. |
