| The present study intended to investigate the effects of different glutathione (GSH) levels (0, 0.1, 0.5 and 1 mM) on the somatic embryogenesis (SE) induction of Acca sellowiana. Besides, we evaluated the effect of different carbon sources (sucrose and maltose) on the somatic embryos conversion. GSH-supplemented treatments resulted in improved SE induction rates (~70%) as compared to the control GSH-free (~35%) after 50 days of culture. The total number of somatic embryos obtained did not differ between treatments, but significant differences were observed for the embryonic stages after 80 days of culture. After 80 days of culture, 0.5 and 1 mM GSH-supplemented treatments showed the largest amount of torpedo-staged somatic embryos. In contrast, treatments... |
