| Resumo: |
The aim of the present work was to establish in vitro conditions for the induction, stabilization and proliferation of embryogenic cultures of A. angustifolia. Pre-cotyledonary staged zygotic embryos inoculated BM medium supplemented with 5 µM 2,4- D, 2 µM BAP and Kin, and 3% maltose or sucrose resulted in 66.7% induction rate. The rate of induction of embryogenic cultures was affected by the carbon source, as well the multiplication and morphology of the embryogenic cultures. Embryogenic cultures maintained in BM medium with maltose presented bipolar morphology. Globular somatic embryos were obtained BM medium with 9% (PEG) and (9%) maltose. These results could establish an in vitro regenerative protocol towards the conservation and improvement of this important species.
