Mountain pine ( Pinus mugo )
Needles, cones and seeds
The dark green, pointed needles are in pairs on the short shoots and are up to 5 cm long. Their lifespan is 5 to 10 years.
The mountain pine is single sexed ( monoecious ), so there are male and female cones on one individual. The pollen is formed at the base of young long shoots instead of leafy short shoots in the axils of scale leaves.
The hard and egg-shaped female cones are set near the end of young long shoots. They hardly grow longer than 10 mm, are pale pink to red and hardly grow until the first autumn. In the second year they grow and mature; then they release the winged seeds . These are 4 to 5 mm in size. The ovules sit open on scale-shaped carpels, so they are not enclosed in an ovary ( naked seed ).
The seed cones are symmetrical; the spiral has asymmetrical cones. The tenon (if any) is centric and straight, i. H. lying in the pin axis. The shield of the seed scales is mostly flat, seldom slightly arched or conical. The cones are between 3 and 7 cm long. If the cones are open, they reach a width between 2 and 5 cm. The flowering period during the summer months of June and July is followed by seed ripening in October. The fruits develop over a period of three years.
The mountain pine occurs in at least three subspecies and other intermediate forms, which differ particularly in their shape and their occurrence. All three subspecies of the mountain pine have the chromosome number 2n = 24. Other authors have the rank of species.
Pinus mugo Turra subsp. mugo (mountain pine, laying pine, crippled pine)
Pinus mugo subsp. mugo , even mountain pine , mountain pine , mountain pine , mountain pine , Legkiefer , Zunter , mountain pine or cripple pine called: This subspecies grows mostly shrubby and reaches stature heights of 1 to 3 meter. It is characterized by its crooked growth with prostrate to arching trunks and branches; these often form an impenetrable tangle ( pine felt or pine field ). The trunk of the mountain pine is long, but lies on the ground and is hardly recognizable.
The main occurrences of mountain pine are in the Alps , the Ore Mountains , the Carpathians , as well as the northern Apennines and the mountains of the Balkan Peninsula ( Balkan Mountains , Dinarides , Pirin , Rhodope Mountains ) at altitudes of 1000 to 2700 meters. In Austria , except for Vienna and Burgenland, it is frequently represented in all federal states.
The mountain pine grows mainly in the subalpine Krummholzzone of ocean high mountains and is there associated with alpine roses . In addition, it inhabits moderately dry, rocky, very wet, cold or destructive snow movements ( avalanches ). Mountain pines, like green alder, can even colonize slopes on which avalanches often break out that completely destroy all other tree species. From locations that are more favorable for tree growth, mountain pines are being displaced by more demanding and there more competitive climax tree species, such as the common beech, provided that the natural competitive conditions are not distorted by game browsing, grazing cattle, alpine and forestry or other human activities. As an ornamental wood, it is often planted in gardens, where it thrives better protected from competing tree species (especially competition from light) in human care than in its natural habitat.
Pinus mugo subsp. uncinata (DC.) Domin (Spirke, hooked pine, upright mountain pine)
Pinus mugo subsp. uncinata , also called Spirke , Hooked Pine or Upright Mountain Pine . Some botanists call it a separate species of Pinus uncinata DC. viewed. The Spirke grows tree-shaped and reaches heights of up to 25 meters.
The hooked pine is found in the Pyrenees , the French Massif Central , the Swiss Jura , the western and central Swiss Alps and the northern Alps (e.g. in the Wimbachtal , Friedergries and the Fernpass as Austria's largest spiral forest). In the Jura it inhabits altitudes from 500 to 1700 meters and in the Valais from 900 to 2300 meters. The Spirke sometimes forms extensive pure stands, but also grows in the lower layers in particular with larch , Swiss stone pine and Scots pine .
Pinus mugo subsp. rotundata (Link) Janch. & H.Neumayer (Moorspirke)
Pinus mugo subsp. rotundata , also called bog mountain pine or bog spirke , is in habitus between the mountain pine and the spirke. Depending on the location, it resembles the leg pine with prostrate branches without a recognizable main trunk or, as an upright, often multi-stemmed tree with a growth height of 8 to 10 meters, the hook pine.
It occurs in the Vosges, the Black Forest, the Alpine Foreland , the Bavarian Forest , South Bohemia, the Fichtel and Ore Mountains and in the Lausitz . The Moor-Spirke is a wood of the montane level and grows mainly at heights between 800 and 1200 meters. In the Allgäu Alps, it rises on the Windecksattel at Gottesacker to an altitude of up to 1750 meters.
The elastic branches are adapted to the winter snow pressure of the high altitudes.
The wood of the mountain pine is hard and difficult to split, i. that is, it has good transverse strength and is not very elastic. Due to its resin content, it gives off a resin odor. It has a reddish core that darkens when exposed to light and a sapwood that is 2 to 4 cm wide and yellowish-white. Also typical are the soapy surface and relatively large branches of dark brown color.
The use of the wood is similar to that of the Scots pine . Since the trunks and branches are not very thick, they can at best be used as wood turners and carved wood, as well as for simple furniture, as planed goods in interior and exterior construction and in window construction. Freshly cut, however, the sapwood is very susceptible to bluish fungus.
Mountain pine oil for cosmetic products is obtained from fresh needles, twig tips and branches . In the distillery , the oil is obtained by means of steam distillation. As a finished mountain pine oil, it can be bottled naturally and offered for sale. It is used both externally and internally for catarrh of the upper and lower respiratory tract. In medicinal baths it is used for the supportive treatment of diseases of the rheumatic type in the non-acute stage.
