    Sammanfattning : The use of so-called micro-plant propagation have become a well-adapted cultivation technique in Swedish forestry nurseries. Although this production method has many advantages, a commonly occurring problem is that the young plants, after trans- plantation in the nursery, have an underdeveloped root system when the shoot part have reached desired length.

  5. 4. Analys av virkeskvalitet i gallringsfri granskog i Dalby

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Joel Engelbrektsson; [2016]
    Nyckelord :gran; gallring; gallringsfritt; virkeskvalitet; kvalitetsegenskaper;

    Sammanfattning : Granen är ett av Sveriges viktigaste trädslag och har stor efterfrågan från industrin. Granen sköts vanligtvis med trakthyggesbruk med markberedning och plantering som föryngringsmetod, med röjning och ett flertal gallringar innan slutavverkning. Problematik kring gran i samband med gallring involverar främst stormskador och rotröta. LÄS MER
