An efficient plant regeneration protocol for shoot organogenesis from Hovenia dulcis callus cultures was established. Induction of organogenic callus was achieved on Murashige and Skoog (MS) medium supplemented with 4.65 lM kinetin and 4.5 lM 2,4-dichlorophenoxyacetic acid (2,4-D). Further differentiation of organogenic callus into primordia, shoot-like structures, and plantlets was achieved on MS medium supplemented with 0.23 lM gibberellic acid (GA 3 ) and 0.46 lM kinetin. Numerous abnormal shoots developed upon transfer of callus to MS medium containing cytokinins, and these failed to grow further into whole plantlets. However, transfer of 'abnormal' shoots to a fresh MS medium lacking cytokinins resulted in growth of normal shoots. Elongated shoots subsequently were rooted in basal MS medium, and whole plantlets were established in a soil mix. Analysis of regenerated plants using random amplified polymorphic DNA (RAPD) confirmed the genetic stability of these regenerant plantlets.

An efficient in vitro plant regeneration system was established from callus culture of Scopolia parviflora. Callus was induced from adventitious roots on B5 medium with 0.45-9.04 μM 2,4-dichlorophenoxyacetic acid (2, 4-D). In vitro plantlet regeneration was achieved on B5 medium supplemented with 44.38 μM benzyladenine (BA), 3% sucrose, and 0.38% gelrite. Plantlets were transplanted to artificial soil and grown to maturity successfully in a greenhouse. The tropane alkaloid contents in regenerated plants were analyzed using high-performance liquid chromatography (HPLC), and were found to be higher than those of adventitious roots, native growing plants, and acclimated plants. Regenerated plants from organogenic callus cultures produced a greater amount of tropane alkaloids.
