- Calycanthus fertilis Walt. is a shrub belonging to the family Calycanthaceae, has great potential as ornamental. In the literature there are no reports on methodpropagation of this shrub in in vitro cultures. Therefore, the aim of this study was a development of the method micropropagation of Calycanthus fertilis Walter. Shoot explants of the size 1 cm, with an apex or node with lateral meristems were placed on the media with mineral composition according to MS and WPM supplemented with BAP (from 0.5 to 2.0 mg·dm–3) and TDZ (from 0.1 to 0.5 mg·dm–3). BAP turnedout to significantly increase initiation frequency whereas TDZ inhibitedthe formation of adventitious shoots andcausedexplant death. The highest percentage of initiated explants were found in shoot fragments placed on WPM medium supplemented with 1.0 mg·dm–3 BAP. Primary explants which initiatedgrowth were transferredon the proliferation media containing WPM macroand microelement, with the addition of different cytokinin: BAP (from 0.5 to 2.5 mg·dm–3), KIN (1.0 to 5.0 mg·dm–3) or TDZ (from 0.1 to 0.5 mg·dm–3). Calycanthus multiplication in vitro shouldbe conductedon WPM media with 1.0 mg·dm–3 BAP. Proliferatedshoots were placedon the WPM rooting medium supplemented with auxins: IBA, IAA or NAA at the concentration from 0.1 to 2.0 mg·dm–3. Maximum rooting was obtained on WPM medium supplemented with 0.5 mg·dm–3 IBA. To sum up, it shouldbe statedthat an efficient method of micropropagation of Calycanthus fertilis Walt. has been developed.
