Abstract

The embryogenic capacity of Araujia sericifera petals and some of the factors involved in the induction of embryos was investigated. The influence of 6-benzyladenine and α-naphthalene acetic acid, light intensity (90 or 5 µmol m-2 s-1) and silver thiosulphate (inhibitor of ethylene action) were studied. It was found that petals are an easy system in which to induce somatic embryogenesis. Plants were recovered from somatic embryos. Although 6-benzyladenine is essential for inducing an efficient response, a high dosage increased callogenesis and reduced embryogenesis. The highest rate of embryogenesis is induced with high light intensity (90–100 µmol m-2 s-1), even though the presence of silver thiosulphate in the medium markedly reduced embryo induction.
