Department of Forest Physiology and Genetics

Long-term stability of forest ecosystems is based on conservation of the adaptability of forest trees to changing environmental conditions. A precondition for sustainable growth of forests and conservation of forest genetic sources is an understanding of the physiology, functional, genetic and species diversity of forest trees and their symbionts.

Our tasks, projects and programmes are based on research and development in the field of forest physiology and genetics, developmental and expert guidance concerning forest reproductive material, fulfilment of obligations deriving from public authorizations, providing advice and transfer of knowledge, and managing the Slovenian Genetic Bank, molecular and biochemical data bases and reference material as well as live collections of forest tree root symbionts.

Our goals are to achieve internationally recognized scientific excellence, transfer knowledge, and provide guidance for the developmental needs and capacities of Slovenian forests and forestry with respect to forest biology and conservation of forest genetic resources, as a precondition for long-term stability of forest ecosystems and their multifunctional role in the preservation of biodiversity and carbon sink modelling.
The activities support programme and project networking, development of employees' capacities and knowledge, equipment and facilities, attainment of scientific criteria, and expert advice-giving.

We are in charge of projects and civil forest service tasks on:

• physiology of forest trees,

• forest genetics, provenance research, and population genetics,

• conservation of forest genetic resources (in situ, ex situ),

• physiology of growth and development, root growth, physiology of symbioses, and stress physiology,

• development of seed and nurseries technologies (seed processing, storage, germination and planting),

• mycorrhiza and interactions in the rhizosphere,

• forest soil biodiversity,

• physiology and ecology of root growth and development,

• myco- and rhizo-bioindication of stress in the rhizosphere,

• molecular ecology,

• biotechnology, biotechnical engineering and myco-rhizo-remediation technologies,

• forest tree plantations, counselling on plant use in energy and biomass plantations .

As the authorized official body for the approval of forest seed objects, certification and diagnostics of forest reproductive material and the diagnostic laboratory for molecular identification of forest pathogens, the Department carries out various tests, keeps registers and issues documents for the needs of the forest inspection service and other commissioners. The results of our research and development contribute to the long-term stability of forest ecosystems and their multifunctional role through conservation of biodiversity and carbon dynamics modelling.
