In vitro propagation of European aspen (Populus tremula L.) from axillary buds via organogenesis
2009
Axillary buds from 1-year-old twigs of European aspen (Populus tremula L.) were used for propagation of indigenous aspen clones for further phytoremedial studies. The most intense bud development was seen after the break of dormancy, i.e. from the middle of February until mid-March. Lower infection rates were observed from the axillary buds collected at an urban forest border in comparison to a forest location, accompanied by higher percentages of browning. The optimal medium for shoot induction primarily via callus cultures was Murashige and Skoog mineral salts medium (MS) supplemented by 20 μM zeatin riboside and 1 μM indol acetic acid. The shoots were rooted in half-strength MS medium supplemented by the same hormones, after which they were successfully transferred to a commercial soil mixture. The protocol for aspen propagation is proposed.
