CO2 enrichment in vitro. Effect on autotrophic and heterotrophic cultures of Nicotiana tabacum (var. Samsun)

  • Marianne Mousseau
Short Communication


Plantlets of Nicotiana tabacum (var. Samsun) were grown under CO2 enriched air supplied by a Warburg buffer. Growth of all plant parts was enhanced. The maximum growth increase was found for roots (120%).

Addition of 30 g.l-1 sucrose in the medium resulted in a three time faster growth. However, the effect of CO2 enrichment was still positive in these conditions, although less pronounced than in autotrophic cultures.
