Abstract:	Sugar beet (Saccharomices cerevisiae var. Saccharifera) is a species of economic and food interest, which, in terms of clonally multiplication, is liable to hyperhydricity. In these studies was identified a method that prevents the hyperhydricity process installation, and at the same time, it increased in vitro plant biomass, using honey, as a replacement for sucrose, and deuterium depleted water (DDW), as a replacement for distilled water (DW), either culture in single-sided, or in the double layer system. Murashige-Skoog mineral culture media, solid, free of growth regulators, prepared with DW or DDW, with the supernatant consist in diluted honey either DW or in DDW were most beneficial in stimulating both the rhysogenesis and the caulogenesis process. The increase of plant biomass in the vitroculture and eliminating waste generated by hyperhydricity has a positive economic impact for producers in this branch.
