Abstract
Shoot-tips of Santolina canescens, an aromatic species producing a novel diacetylene derivative, were in vitromultiplied on Murashige-Skoog basal medium (MS) containing different concentrations of 6-benzyladenine (BA) and kinetin (KIN). Rooting phase was performed on media supplemented with different auxins: 3-indoleacetic acid (IAA), 3-indolebutyric acid (IBA) and 1-naphthaleneacetic acid (NAA). The best axillary-bud proliferation was recorded on MS medium containing 1.33 μM BA plus 0.32 μM NAA. Plantlets rooted easily on the different tested media, but more abundant and stronger roots occurred on media containing 2.68 μM NAA. The composition of oil obtained through the cultured explants was analyzed by headspace gas chromatography (HS-GC), and santolindiacetylene (SDA) in vitro production was tested. In order to stimulate the production of this product, different concentrations of linoleic acid were supplemented to the media. The best santolindiacetylene production was obtained when the rooting media was supplemented with 0.36 μM linoleic acid.
