Abstract
An efficient protocol for in vitro propagation of the valuable ornamental and medicinal plant Bush germander (Teucrium fruticans L.) was developed through axillary shoot proliferation. A Murashige and Skoog agar medium supplemented with benzylaminopurine (6.6 μM), α-naphthaleneacetic acid (0.053 μM), and sucrose (3%) significantly improved the production of multiple shoots directly from nodal segment explants, resulting in an average of 2.8 shoots per segment with an average of 6.8 nodes per shoot that would be potential newly formed explants. The new shoots were developed without a marked decrease in the average height of the shoots. Shoots treated with 2.5 μM indole-3-butyric acid showed the highest average root number (7.9) and the highest percentage of rooting (94%). Plantlets were hardened off and transferred to jiffy pots for acclimatization under greenhouse conditions, resulting in a 100% survival rate.
