THE TI RESEARCH WORK WILL COVER:
1. RAW MATERIAL: THE VARIATION OF THE PERMEABILITY IN NORWAY SPRUCE (PICEA ABIES (L.) KARST.) FROM VARIOUS FOREST SITES (EFFECT OF SOIL, TIME OF FELLING, EFFECT OF THINNING, GENETICS).
THE AIM WILL BE TO ESTABLISH A KNOWLEDGE FOR SELECTING/BREEDING SPRUCE WITH A PERMEABILITY ADAPTED TO DIFFERENT END USE I.E.:PRESERVATION (HIGH PERMEABILITY), JOINERY (NATURAL LOW PERMEABILITY).
2. SAWN-MATERIAL AFTER FELLING: CHANGES IN ORIGINAL PERMEABILITY IN THE GREEN SPRUCE WHEN SAWN AND DRIED IN THE LABORATORY UNDER DIFFERENT SCHEDULES.
THE AIM OF THIS RESEARCH WILL BE A BASIS FOR SUCH CHANGES (DEVELOPMENT) OF SCHEDULES WHICH WILL CONSERVE OR ALTER THE SPECIFIC PERMEABILITY OF THE GREEN SPRUCE, DEPENDING ON END USE PART 1.
3. CHANGES WITH TIME: STUDYING THE PERMEABILITY-PERMANENCE IN SPRUCE EXPOSED OUTDOOR WITH TIME: EXAMINATION OF THE PERMEABILITY ONCE A YEAR 1983-85 ON SPRUCE FROM PART 2 AND FROM SPRUCE IN EXISTING FIELD-TESTS.
