    Abstract The tree fern Alsophila odonelliana is found from southern Bolivia to northwestern Argentina, in the Tucuman-Bolivian forests. Spore germination was tested in three sterile nutritive media: Dyer (D), Murashige and Skoog (MS) and Knudson (K). We also evaluated the effect on gametophyte development of the addition of two growth regulators, BAP and 2,4-D to the culture medium Dyer; 2,4-D was evaluated using two concentrations: 0.1 and 2.0 mg/L, and BAP using three concentrations, 0.01; 0.1 and 1.0 mg/L. We found no significant differences in the germination of spores among all three media. We noted that supplementing media with BAP affected… More >
