Abstract
|
|
|
|
Optimal culture conditions for efficient in vitro propagation and polysaccharide production of Orostachys japonicus were established. O. japonicus was cultured in media containing various growth regulators and carbon sources. The highest regeneration rate was achieved in 1.0 and 3.0;mg;l;^{-1} of 2,4-D concentration, while the lowest was obtained in 10.0;mg;l;^{-1} 2,4-D concentration. When different carbone sources were added in the culture medium, plant growth was high in 3% sucrose treatment. The micropropagated shoots were successfully acclimatized in artificial soils and produced comparable amont of polysaccharide compred to parent cultivated plants.
