Medium-Term Preservation by the In Vitro Minimum Growth Method of Cedrela odorata L.

Area of Science:

• Botany
• Conservation Biology
• Plant Science

Background:

• Cedrela odorata L. is a high-value timber species facing overexploitation and population decline.
• It is listed under Mexican Official Standard NOM-059-SEMARNAT-2010 and CITES, highlighting its endangered status.
• Ex situ conservation is crucial for threatened species like Cedrela odorata L.

Purpose of the Study:

• To evaluate minimum growth in vitro as an ex situ conservation method for Cedrela odorata L.
• To determine the efficacy of this method for medium-term germplasm safeguarding.

Main Methods:

• Implementing minimum growth in vitro techniques for Cedrela odorata L. germplasm.
• Maintaining plant material in vitro for extended periods (9 months to 1 year) on the same culture medium.

Main Results:

• Minimum growth in vitro proved to be an efficient alternative for conserving Cedrela odorata L. germplasm.
• The method allows for successful medium-term conservation, maintaining plant material for up to one year in vitro.

Conclusions:

• Minimum growth in vitro is a viable and complementary strategy for the ex situ conservation of endangered Cedrela odorata L.
• This method contributes to safeguarding the genetic resources of species listed under SEMARNAT's NOM 059.
