| 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 the longitudinal growth of the filamentous gametophytes, and the proliferation of ramifications from early stages.... |
