Abstract
Epicotyl, petiole, and cotyledon explants derived from 14-d-old seedlings of Albizia odoratissima were cultured on Murashige and Skoog (MS) basal medium supplemented with different concentrations of either 6-benzylaminopurine (BAP) solely or in combination with 0.5 μM naphthalene-3-acetic acid (NAA). The percentage of shoot regeneration and the number of shoots regenerated varied significantly depending on the type of explants used, the concentration of plant growth regulators, and the orientation of explants on the culture medium. The best response in terms of the percentage of shoot regeneration was obtained from epicotyls cultured horizontally on MS medium supplemented with 5 μM BAP, whereas the highest number of shoots per responding explant was recorded on medium containing 2.5 μM BAP and 0.5 μM NAA. Successful rooting was achieved by placing the microshoots onto MS medium containing 25 μM indole-3-butyric acid (IBA) for 24 h first, then transferring to the same medium without IBA. Of the various substrates tested, vermiculite was the best for plant acclimatization, as 75% of the plants survived and became established.
