Vegetative propagation can produce well-known and homogeneous plant material for different uses of forest biomass. The aim of the project is to improve the cost-effectiveness of the technology based on spruce embryo reproduction (somatic embryogenesis, SE) at the various stages of production, as well as to pilot the breeding of SE seedlings in cooperation with the industry. In the project, the efficiency of the research laboratory producing spruce cellular lines will be improved through databases and identification systems that allow lighting, bioreactor applications and large quantities of lines to be handled by LED technology. This will result in an increased number of laboratory-tested lines for field testing, which is important for obtaining high-quality and hereditary forest reproductive material. Field testing will be accelerated by integrating cell nursery production and cutting technologies. At the same time, it will be examined whether integration can also improve the progress of forest breeding. Cellular seedling production chains could be built on the model of smart specialisation and partnership between different actors. The project examines how the growth of cellular seedlings can be achieved in a modern nursery intended for conventional seedling production, on the one hand, and on the other hand, in the operation of mass reproduction in bioreactors in solution breeding, developed in Sweden. As a result, the amount of handicrafts in the production and testauprosts of cellular seedlings can be reduced, thereby improving cost and energy efficiency. The project will result in a clearer division of roles between research and commercial mass production, allowing actors to assess opportunities for specialisation and partnership.
