… the correlation between tetratherm and the growth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms the usefulness of digital terrain models in providing data for a lot of different factors and for the tetratherm model. Hopefully will this tetratherm map …
tillväxt och höjdutveckling i Siljansfors försökspark
Sibirisk lärk (Larix sibirica och Larix sukaczewii) är ett snabbväxande barrträd som odlats i Sverige i mer än 100 år. Trots det finns det få studier angående dess potential i Sverige och dessutom visar studierna på skilda resultat. Med data från bestånden med sibirisk lärk i …
en jämförelse efter stormen Gudrun
… wind tolerant than spruce. The method was to compare larch, Japanese larch (Larix kaempferi Lamb.), European larch (L. decidua Mill.) and hybrid larch, (L. x eurolepis A. Henry) and spruce growing side by side and with equivalent premises. Totally 26 pairs of larch and 34 stands …
… In this work for cultivation with Pinus contorta var. latifolia Engelm., Larix sukaczewii Dylis, Abies lasiocarpa (Hook.) Nutt., Populus × wettsteinii Hämet-Ahti (tremula x tremuloides) and Picea mariana (Mill.) Britton et.al. for increased volume growth per hectare in northern …
The effectiveness of Phlebiopsis gigantea to prevent spore infections from Heterobasidionannosum and Heterobasidion parviporum on hybrid larch stumps were investigated in fivestands in southern Sweden. All sites are former forest land and the age of the trees wasbetween 9 and 13 …
… of this report is to describe and evaluate an experiment with hybrid larch (Larix x eurolepis) as shelter wood, and different tree species growth and survival depending on the density of the shelter wood. The experiment is conducted by southern Swedish forest research centre …
… has grown. One tree species that has become very interesting is hybrid larch (Larix × eurolepis Henry.), regarded as a fast growing species. Hybrid larch don’t differ from spruce when it comes to Heterobasidion annosum, it gets sever damages as well. The objectives with this …
The purpose of this study was to show how the Hybrid Larch (Larix eurolepis x) are used by large herbivores in terms of grazing and fraying. More specifically I studied how impact on the seedlings was affected by forest stand area, tree height and stem density (stems/ha).The …
hur påverkas produktionen i blandbestånd jämfört med trädslagsrena bestånd?
The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests. The purpose …
-Designförslag i tre tänkta miljöer
Denna uppsats presenterar tre designförslag på samplanteringar med barrväxter i fokus. Designförslagen är gjorda till tre fiktiva platser med olika ståndort i växtzon 5, en liten entréplantering i västerläge med kalkhaltig jord, en mellanstor plantering i söderslänt med …
