Abstract [sv]

Den här studien är en uppföljning av föryngringsresultatet efter maskinell sådd av contorta (

Pinus contorta Dougl. var. latifolia Engelm.) i Härjedalen. Efter tre växtsäsonger uppgick det totala antalet såddplantor till 3 700 per ha och antalet huvudplantor uppgick till 1 800 per ha. Andelen nollytor uppgick till 2 %. Det var ingen skillnad i föryngringsresultat mellan låg och hög altitud.

Generellt gav maskinell sådd av contorta ett tillfredsställande föryngringsresultat. På mindre bördig mark var såväl det totala antalet såddplantor som antalet huvudplantor högre än på bördigare mark.

Abstract [en]

Mechanical regeneration by seeding of lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) in the province of Härjedalen in Sweden was studied. After three growing seasons the total number of seedlings were 3 700 per ha and the number of main seedlings were 1 800 per ha. 2% of the sample plots had no plants within 3 m. No difference could be found between objects on high and low altitudes.

In general mechanical seeding gave satisfactory regeneration. On low fertile soils the total number of seedlings as well as the future main seedlings was higher than on more fertile soils.
