Embu).  c2000  aThe influence of increasing concentrations of naphthaleneacetic acid and the antibiotics cefotaxim?, timentin, kanamycin, and hygromycin on eggplant (Solanum melongena L. cv. Emb£) somatic embryogenesis was investigated. Cotyledon explants were excised from 16 to 20 days old in vitro grown seedlings. NAA promoted somatic embryogenesis, although its concentrations had no influence on the mean number of embryos. Callusing decreased significantly with increasing NAA concenti-ations. Morphogenesis was stopped with 50 to 100 mg L-I kanamycin and 7.5 to 15 mg L-I hygromycin. Although early globular embryos were observed up to 15 mg L-I, further embryo development was inhibited at 10 mg L .1. Interestingly, cefotaxime (250 and 500 mg L -1) promoted a marked effect on enhancing fresh weight of calli, accompanied by decrease in embryo regeneration, whereas timentin concentrations (150 and 300 mg L-I) did not affect embryo differentiation as compared to the control treatment.  aantibiotics  aembryogenesis  apotassium  aAntibiótico  aBerinjela  aEmbriogénese  aPotássio  aSolanum Melongena  aAubergine1 aOTONI, W.
