Abstract

Conditions for induction of callus formation from root and stem explants and long-term maintenance of Deschampsia antarctica Desv. tissue culture have been specified. Ability to callus formation depended on mineral composition of nutrient medium, combination of growth regulator concentrations, place of donor-plant vegetation and type of explant. The optimal for callus tissue generation was Gamborg, Eveleigh — B 5 nut rient medium, supplemented with 0.9–1.0 mg/l 2.4-dichlorophenyl acetic acid and 0.09–0.1 mg/l of cytokinine benzylaminopurine. Callus formation potency from the root explants considerably exceeded (1.5–2 times) that of from stem ones. The shoots were derived through spontaneous indirect organogenesis. Regeneration efficiency was found to be affected by nutrient medium composition and callus origin. Regenerated shoots were rooted and conditions for growth of regenerated plants in vitro were specified.
