PAULOWNIA TOMENTOSA L. IN VITRO PROPAGATION
Journal Title: Natural Resources and Sustainable Development - Year 2016, Vol 6, Issue 1
Abstract
The purpose of this study was to obtain in vitro Paulownia tomentosa L. vigorous and less expensive seedlings than the traditional method. Micropropagation was performed starting from the seed germinated made in sterile culture medium Murashihe-Skoog (1962) ½ with Gamborg et al. (1968) ½ vitamin, solid, without growth regulators. At 3 months from the germinated were obtained seedlings with 3-4 cm stem size with a well-developed root system, capable to ex vitro transfer. Plantlets acclimatization survival percentage was 65% in peat: perlite 2: 1 substrate. By comparison with traditional breeding methods we found that the production of in vitro seedlings assumed three times less cost, but it disadvantage is still producing clones devoid of genetic variability.
