In vitro adventitious shoot regeneration and acclimatisation of Brassica oleracea subsp. italica cv. Green Marvel
Cotyledonary explants of Brassica oleracea subsp. italica (broccoli) cv. Green Marvel were cultured on Murashige and Skoog (MS) medium containing different combinations of the growth regulators 6- benzylaminopurine (BAP) and α-naphthalene acetic acid (NAA) for shoot regeneration. The optimal medium...

| Summary: | Cotyledonary explants of Brassica oleracea subsp. italica (broccoli) cv. Green Marvel were cultured on Murashige and Skoog (MS) medium containing different combinations of the growth regulators 6- benzylaminopurine (BAP) and α-naphthalene acetic acid (NAA) for shoot regeneration. The optimal medium for inducing shoots contained 3 mgl-1 BAP and 1 mgl-1 NAA, which produced a shoot induction percentage of 53.33% and a mean number of 0.43 shoot per explant. The shoots were subsequently rooted in MS medium that contained 0.2 mgl-1 of indol-3-butyric acid (IBA). Different potting media were assessed during plantlet acclimatization. The highest percentage of plant survival (83.33%) was on the medium that contained sand and soil (1:1), while maximum root length (4.37 cm) and plant height (7.87 cm) were attained in potting medium that consisted peat moss, perlite and vermiculite (3:1:1). |
