The production of biologically active substances by plant cell cultures inspace

The impact of the conditions of space flight on the productivity of culture s of the plant cells with respect to the biomass and the metabolites is inv estigated. The experiments were performed with the callus cultures of the c ells of ginseng (Panax ginseng), red root puccoon (Lithospermum arythrorhiz on), and macrotomia coloring (Macrotomia euchroma) onboard the orbital stat ion Mir and American Space Shuttle. A more pronounced variation of the outp ut of the metabolites is noted with respect to the ground control. This out put depends upon the properties of the strain and conditions of the experim ent.
