JIMENEZ, VÍCTOR M.. Regulation of in vitro somatic embryogenesis with emphasis on to the role of endogenous hormones. Rev. Bras. Fisiol. Veg. [online]. 2001, vol.13, n.2, pp.196-223. ISSN 0103-3131.

Different aspects of the in vitro somatic embryogenesis regulation are reviewed in this A description of g General aspects, such as terminology, uses, stages of development and factors associated with the somatic embryogenesis, are described. is carried out. Although a brief description ofn the effects of the addition of different plant growth regulators to the culture medium wasis given, the article is centereds itself on the effect that the endogenous hormone concentrations in the initial explants and in the tissue cultures derived from them could play oin the induction and expression of somatic embryogenesis. It is significant that few to emphasize the low amount of systematic studies have been conducted, in this subject, in which different species and hormone groups were compared in cultures with and without embryogenic capacity. Moreover, the lack of correlation between the results presented in different studies the distinct works indicates that the hormone content of the cultures is not the only factor involved.
