Introduction in culture in vitro of Deschampsia аntarctica Desv. (Poaceae) from two regions of Maritime Antarctica

Abstract

There were developed conditions for seeds germination, micropropagation as well as for induction of callus formation from root and stem explants for a long-term Deschampsia antarctica Desv. tissue culture growing. Optimal for micropropagation of the species was nutrient medium B5 with 0,2 mg/l Kin; for callusogenesis of both explants types – the same medium supplemented with 0,9 mg/l 2,4-D and 0,09 mg/l BAP. Callusogenesis from the root explants considerably exceeded (2-2,6 times) that from the stem one.
