Abstract: Activated carbon is often used to improve cell growth and development in somatic embryogenesis. In this study, three types of activated carbon, including phosphoric acid activated carbon, activated carbon for refinement of injection and activated carbon purchased from Sigma were added respectively to the mediums for improving somatic embryogenesis frequency of two genotypes of cell lines in Liriodendron hybrids. The number of total somatic embryos and cotyledon embryos were counted, pH and osmotic pressure of the mediums were detected, and the adsorption ability of activated carbon were analyzed to select the most suitable activated carbonl and to find their potential effects on somatic embryogenesis of Liriodendron hybrids. The results showed that the first two types of activated carbon induced more total somatic embryos and cotyledon embryos than the third type, especially the activated carbon for refinement of injection. The adsorption ability of activated carbon for refinement of injection was moderate among the three, and the pH and osmotic pressure of the mediums containing it were also temperate compared with the other two types of activated carbon. It was concluded from the results that the adsorption ability of activated carbon may change the pH and osmotic pressure of mediums directly to influence the somatic embryogenesis of Liriodendron hybrids.
