Hevea : micropropagation by somatic embryogenesis

The different steps of the process for maintained somatic embryogenesis were described. The current yields of the process were shown. They led to discuss on the limiting factors with the prospect of mass micropropagation. The first field trial with five, years old vitroplants was analysed. First conclusions were promising. Some ways were proposed for the next years, in order to achieve the development of the process and to integrate it into the strategy for rubber tree improvement
