Summary
Shoot organogenesis of Guazuma crinita Mart. from root and petiole explants was obtained via adventitious bud formation. Root segments and petiole explants excised from in vitro generated plantlets were cultured on woody plant medium (WPM) supplemented with [trans-6-(4-hydroxy-3-methylbut-2- enyl)aminopurine] (zeatin) or with [6-benzyladenine] (BA). After 45 d of culturing, clumps of green bulbous structures containing small adventitious buds (clusters) were generated in all explants cultured with 10 µM zeatin under a photon flux density of 65 µmol m−2 s−1. For subsequent shoot differentiation, clusters were transferred onto medium containing 1 µM zeatin. After 60 d of culturing, 30% of clusters generated from petiole explants developed into plants. The regenerated plantlets were successfully acclimatized and all survived and grew well. No morphological abnormalities were observed.
