BA increased the rate of germination and the number of lateral shoots (3,4 vs 1,2 per seedling). Stem nodes from these lateral shoots were cultured on proliferation media with 4,.4 uM BA, and multiple shoots (3.5) were formed within 4 weeks of culture. Increasing the concentration of BA or the addition of naphthaleneacetic acid (NAA) did not affect shoot formation.Shoots produced from explants and lateral shoots from germinated sedlings were rooted in media containing activated charcoal (AC) or 9,8 uM indolebutyric acid (IBA). Shoots rooted with IBA had a higher rooting percentage (100% vs 75%) and a greater number of roots (5.5 vs 3.2) but the shoots were shorter (2.6 vs 3.4 cm) than when rooted in AC, and they required an additional 4 weeks of culture in media hith AC to achieve shoot elongation. About 80% of the shoots with roots survived in the glasshouse and produced normal phenotypic plants. agermination atissue culture aGerminação aGoiaba aAC-activated charcoal aBA-benzyladenine acultura de tecidos aIBA-indole-3-butyric acid aMS-Murashige and Skoog (1962) medium aNAA-1-naphthaleneacetic acid aPropagacao aSeed aSelection aSementes aShoot aTDZ-thidiazuron1 aBARRINGER, S.
