The proposed procedure allowed approximately tenfold shortening of the species developmental stages with the omission of the gametophyte stage while the sporophyte mass could be increased tenfold within a 6-month period. The cultures were established using vegetative propagules (bulbils) procured from sporophytes growing in the wild without degrading the habitats of this endangered plant species. Explants underwent surface and internal disinfection to eliminate the epiphytic and endophytic bacteria and fungi. In in vitro cultures, the optimum results were achieved using Moore (Mr) medium without growth regulators or supplemented with 0.015 mg/l IBA and 0.3 mg/l kinetin. These media ensured both viability of the propagules and their further development. The biomass growth index for H. selago sporophytes grown from propagules, determined at 3 months of culture (1 passage) on Mr medium with IBA and kinetin was 650%. At 6 months, the biomass growth index increased to 1114%. Vigorous growth of adventitious roots, especially on Mr medium with the addition of 0.25 mg/l NAA, and callus formation on shoot apices were observed. At 6 months of culture, some sporophytes obtained from the bulbils were used as the initiating material for shoot subcultures, which developed best on Mr medium with IBA and kinetin."
