Micropropagation of English Yew, an Ornamental-Medicinal Tree

An in vitro propagation method of English yew (Taxus baccata L.) through organogenesis method using kinetin (Kin) and indole 3-butyric acid (IBA) as plant growth regulators and apical bud as explant is presented. Apical buds excised from mother plants were inoculated on Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of Kin (0.00, 0.50, 1.00 and 2.00 mg l–1) as a cytokinin and IBA (0.00, 0.50, 1.00 and 2.00 mg l–1) as an auxin. Results showed that the highest number of node (6.75) was obtained on MS medium containing 2.00 mg l–1 Kin. The maximum shoot number (5.00) was obtained on MS medium supplemented with 1.00 mg l–1 Kin together with 1.00 mg l–1 IBA. The largest number of root (6.50) was produced on explants grown on medium enriched with 2.00 mg l–1 Kin together with 1.00 mg l–1 IBA. Plantlets were transferred to pots filled with perlite and peat moss in equal proportions for acclimatization. These plantlets were acclimated and successfully established in cultivation beds. .
