Résumé :

Forests and forest-wood sector are considered as key players towards de-carbonation of the economy worldwide and mitigation of climate change. It is the dynamic forest management for wood production that would likely contribute to reduce (carbon sequestration) or prevent greenhouse gas emission (material and energy substitution) while increasing the flexibility to adapt forests to climate change. Intensively managed plantation forests are expected to play a major role, especially faster-growing and more successful conifers for reforestation. This will require however significant capacity to produce high-quality seedlings at reduced cost. Reproduction strategies of selected varieties based on vegetative propagation may therefore become more essential in the near future to continuously improve upon wood biomass production. Micropropagation technologies are promising for scaling-up the production of many forest tree species, especially conifers. However forest biotechnologists are facing recurrent problems for decades, i.e. low genotype capture and yield during the process and poor plant quality compared to reference seedlings. The presentation will highlight some ongoing tissue culture strategies and challenges to make biotech forest a reality in the bioeconomy era.
