Abstract

A comparison of different species and of Daucus showed that the capacity of their petioles for somatic embryogenesis correlates broadly with the endogenous ABA concentration before culture. Here the competence for this process decreases with lower endogenous ABA concentrations. In some cases somatic embryogenesis could be improved or promoted by an application of ABA to the nutrient medium. Whereas for differentiation and further development of Somatic embryos the concentration of ABA seems to be essential, the induction of somatic embryogenesis seems to depend also on the concentration ratio of endogenous ABA/auxin.
