Genetic Conservation

First Era: tree introduction, species trail,

botanical garden)

Second Era: tree breeding

(provenance trails, progeny test)

Third Era: Linked with breeding

& biotechnology – DNA Molecular)

Lesson learned from experience

• Seed source from (improved) plantation

is better than from natural forest.

• Breeding strategies of (each) species

should be developed.

• Biotechnology help to enhance

effectiveness and speed up of improved seed source establishment.

• Seed exchange is necessary for effective

genetic test.

Approaches under Climate Changes: Options for future management

• Develop specific breeding program

(well adapted to changing environment)

• Ensuring quantity and quality of

seed sources

• Establish static conservation

(Cryopreservation, cold storage freeze preservation of vegetative part) to preserve improved genetic materials

Development of cryopreservation techniques for long-term in vitro conservation of Siamese Rosewood (Dalbergia cochinchinensis Pierre)

Keep the shoots in Liquid nitrogen (-196 celcius) Shoots from tissue culture
