To find the optimal basal medium, shoots were grown on four different media: olive medium (OM) and three modified OM media enriched with 2, 4, and 10 times the iron (Fe), magnesium (Mg), and manganese (Mn) concentrations of the OM medium, respectively (OMG, OMG<jats:sub>4<\/jats:sub>, and OMG<jats:sub>10<\/jats:sub>). For the elongation\u2013proliferation stage, media were supplemented with 9.12\u00a0\u00b5mol\u00b7L<jats:sup>\u20131<\/jats:sup> zeatin. Doubling the Fe, Mg, and Mn concentrations (OMG) provided green and healthy shoots, while in other media leaf chlorosis or necrosis and abscission occurred because of either deficiency (OM) or toxicity of the elements (OMG<jats:sub>4<\/jats:sub> and OMG<jats:sub>10<\/jats:sub>). Shoots grown in the OMG medium also had the highest elongation\u2013proliferation rates. Physiological studies were then performed only between OMG- and OM-grown shoots. Chlorophyll a and b contents and fluorescence (F<jats:sub>v<\/jats:sub>, F<jats:sub>m<\/jats:sub>) were higher in OMG-grown shoots. Doubling the concentration of Fe, Mg, and Mn (which are important in photosynthesis) stimulated leaf survival and photosynthesis. OMG-grown leaves had higher Mg, Fe, and Mn levels. Compared with field leaves, in vitro leaves had higher protein contents. Other physiological parameters (membrane integrity, water content, and osmolality) did not differ between the two media. The best rooting rates were obtained for shoots grown in OMG (&gt;85%), and plants were successfully acclimatized. These studies improved the efficiency and quality of micropropagation of O. maderensis, thereby allowing germplasm preservation of this endangered species. <\/jats:p>","DOI":"10.1139\/x09-011","type":"journal-article","created":{"date-parts":[[2009,4,17]],"date-time":"2009-04-17T17:01:01Z","timestamp":1239987661000},"page":"814-822","source":"Crossref","is-referenced-by-count":6,"title":["Basal medium improvement for routine micropropagation of <i>Olea maderensis<\/i>: physiological comparative studies"],"prefix":"10.1139","volume":"39","author":[{"given":"Gina","family":"Brito","sequence":"first","affiliation":[{"name":"Laboratory of Biotechnology and Cytomics, CESAM and Department of Biology, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal."}]},{"given":"Concei\u00e7\u00e3o","family":"Santos","sequence":"additional","affiliation":[{"name":"Laboratory of Biotechnology and Cytomics, CESAM and Department of Biology, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal."}]}],"member":"155","reference":[{"key":"rg1\/ref1","unstructured":"Albar\u00e8de, F. 2007.
