A protocol is described for the adventitious shoot bud regeneration from leaf and stem explants in Aesculus hippocastanum. Effect of different media (Heller, WPM, Rugini and DKW) and growth regulators (BA, TDZ and NAA) combinations on shoot organogenesis were examined. Culture medium content had a significant effect on shoot regeneration in Aesculus. The highest shoot number and length was achieved on Rugini and WPM medium. Adventitious shoot formation was observed in all types of explants. Regeneration frequency and shoot number depended on explant type and growth regulators. The highest regeneration (100%) and the highest shoot bud number (9.7) were recorded in stem explants on WPM medium with 8.9μM BA+0.5μM NAA. Generally, TDZ was less effective on shoot regeneration in stem and leaf explants compared to BA. The addition of NAA to the culture medium improved shoot regeneration from stem discs. Rooting of elongated shoots was significantly increased (68.1%) on full-strength WPM medium supplemented with 2.7μM NAA. Rooted plantlets were acclimatized successfully under greenhouse conditions.
