Pinus koraiensis | |
Pinus koraiensis is a species of pine known commonly as the Korean pine. It is a relic species of the Tertiary, identified as a rare tree species by United Nations. [2] It is native to eastern Asia: Korea, northeastern China, Mongolia, the temperate rainforests of the Russian Far East, and central Japan. In the north of its range, it grows at moderate elevations, typically 600 to 900 metres (2,000 to 3,000 feet), whereas further south, it is a mountain tree, growing at 2,000 to 2,600 m (6,600 to 8,500 ft) elevation in Japan. [1] Other common names include Chinese pinenut. [3] The ancient woodland of P. koraiensis on the earth is about 50 million hectares, and China has about 30 million hectares, accounting for 60%. [4] It is a second-class national key protected plant in China. [4] P. koraiensis is a tree species with high economic and ecological value. The official name in Chinese is "红松 hóng sōng/red pine", because almost every part of it is related to red. [5]
According to research, P. koraiensis can be divided into two natural types according to the thickness of the bark, namely Pinus koraiensis Sieb. et Zucc. f. pachidermis Wang et Chi and Pinus koraiensis Sieb. et Zucc. f. leptodermis Wang et Chi. [5]
P. koraiensis is a member of the white pine group, Pinus , section Quinquefoliae. Cultivated specimens may grow to about 9 to 15 m (30 to 50 ft) tall, whereas in their native habitat and growing conditions they can reach as much as 30 m (100 ft) or even 50 m (160 ft) in height. [6] [5] It is pyramidal in shape, with younger specimens having ascending branches and older trees having more horizontal branches that reach ground level. The gray or brownish bark flakes off to reveal reddish inner bark. The sapwood is yellowish white, while the heartwood is light yellowish-brown or light reddish-brown. [5] The branchlets and winter buds are also reddish-brown. [5] The branches are lined with bundles of five blue-green needles, each up to 115 mm (4+1⁄2 in), and bear brown cones up to 150 mm (6 in) long. [6] In Northeast China, a particularly large cone is nearly 200 mm (7.9 in) long and 100 mm (3.9 in) in diameter. The seeds take two years of growth to mature, and the mature seeds do not fall off. [5] The cones release a strong scent that is so irresistible to animals that they help to open the hard cones allowing the seeds to disperse. The nutshells are reddish brown. P. koraiensis is monoecious with different flowers. Male cones are reddish-yellow, mostly clustered in the lower part of new branches to form spikes; female cones are green-brown, solitary or in groups near the top of new branches. [5] P. koraiensis can live up to 700 years; after 100–200 years of growth, it enters the fruitful youth stage, and after 300–400 years, it enters the fruitful adult stage. [4] The wild P. koraiensis grows very slowly, it takes fifty or even eighty years to bear fruit, and the cultivated P. koraiensis usually takes more than twenty years to bear fruit, but grafted seedlings can bear fruit within a few years. [4]
P. koraiensis is a precious tree species with both economic and ecological value. Ecologically, it has the functions of water and soil conservation - its root has a large water storage capacity, which is a "small reservoir" in the eyes of ecologists - and the function of maintaining biodiversity. Economically, every part of the plant can be used. In China, it has a long history of being used in food, beverage, health preservation and medical treatment. The ancients called its fruit "長壽果/longevity fruit". [5] The traditional Chinese medicine "海松子/sea-pine nut" refers to the seeds of P. koraiensis, which is a nourishing and strengthening agent. [5] At present, the high-tech industry of P. koraiensis has outstanding achievements in the fields of food, health products, medicine, cosmetics and fine chemicals.
The nuts of this tree are edible and sold commercially. [6] It is the most common taxon sold as pine nuts in markets throughout Europe and the United States. [1] The nut oil contains 11.5% of the unusual fatty acid pinolenic acid (cis–5–cis–9–cis–12 octadecatrienoic acid). [7] It "has a variety of physiological effects such as weight loss, lipid lowering, immune enhancement, anti-inflammation, anti-oxidation, enhancement of insulin sensitivity, and anti-tumor metastasis." [8] Pine nut oil extracted from P. koraiensis nuts has high nutritional value. The oil is also used to make lubricants and soap. [9] The tree is a source of turpentine resin and tannin. [1] [10] The pine needles can be used to extract pine needle oil.
松花粉/Pine pollen is the dried pollen produced by the stamens. It is a traditional Chinese medicine and a traditional Chinese cooking ingredient. It is even used as the name of cakes or drinks, such as "松花糕/pine flower cake", "松花酒/pine flower wine" etc. ""中国预防医学科学院营养与食品卫生研究所/The Institute of Nutrition and Food Hygiene of the Chinese Academy of Preventive Medicine" has confirmed that pine pollen contains more than 200 nutritional components and bioactive substances, with anti-fatigue, anti-aging, regulating blood lipids, enhancing immunity, and beautifying five major health care functions". [11] ""国家体育总局运动医学研究所兴奋剂检测中心/The Doping Testing Center of the Institute of Sports Medicine of China" indicated that no ingredients banned by the Olympic Games were found in pine pollen". [11]
The Korean pine is used as an ornamental tree. It is tolerant of several soil types and thrives in urban settings. It is adapted to climates with very cold winters. [6] There are several cultivars, including the blue-tinged 'Glauca' and 'Silveray' and the wide-bodied 'Winton'. [12] The Korean pine is also a good tree species for afforestation in Northeast China. [4]
The wood is versatile and very useful for construction. [6] It is light, with straight grains, and easy to work. It is used for a great variety of products, including telephone poles, railroad ties, bridges, boats, plywood and flooring, furniture, sports equipment, and musical instruments. It is easy to break down into chips, particle board, or pulp for paper. [1] The fatwood used to be the best kindling in the forest area of Northeast China, and now it is a rare objet. The carvings or prayer beads made of it are collected or used like precious ancient objects. [4]
The value of P. koraiensis has led to overexploitation of wild populations of the tree, and destruction of the forest ecosystems in which it grows. The Siberian tiger is resident in these pine forests, and preservation of this tree species is one step in the conservation of the tiger. [1]
Other associates of the tree in nature include the spotted nutcracker (Nucifraga caryocatactes), which collects the seeds and plays an important role in their dispersal. [13]
In China, the ancient P. koraiensis forests are concentrated in the Paektu Mountain and Lesser Khingan areas, and are the building species of the natural forests in the northeast. Except for the pure P. koraiensis forests in some areas, most of them are mixed with other coniferous and broad-leaved tree species. [5] The broad-leaved-P. koraiensis forest preserves the ancient structural characteristics of the Tertiary plant community. It is a climax community in Northeast China, and its ecological value is extremely precious. It maintains ecological balance and ecological security in Northeast China. [4] Yichun located in Lesser Khingan has the most typical and best-preserved P. koraiensis virgin forest community in Asia. [14] Yichun has two national nature reserves, 丰林/Fenglin and 涼水/Liangshui, which specialize in the protection of P. koraiensis. Among them, Fenglin Nature Reserve has been included in the World Network of Biosphere Reserves" by UNESCO. The P. koraiensis virgin forest community in Yichun is an important gene pool of China's biodiversity. "There are more than 110 kinds of precious coniferous and broad-leaved trees, more than 60 kinds of large mammalian wild animals, and more than 270 kinds of birds, including 64 kinds of national first-class and second-class protected animals; there are 1390 kinds of plants, including more than 700 kinds of wild medicinal materials". [14] Since 2004, the logging of wild P. koraiensis trees has been completely prohibited in Yichun, and the existing P. koraiensis trees have been registered one by one for protection. [2]
A pine is any conifer tree or shrub in the genus Pinus of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta, also known as Coniferophyta or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews. As of 2002, Pinophyta contained seven families, 60 to 65 genera, and more than 600 living species.
The nutcrackers (Nucifraga) are a genus of four species of passerine bird, in the family Corvidae, related to the jays and crows.
Pine nuts, also called piñón, pinoli, or pignoli, are the edible seeds of pines. According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible but are too small to be of notable value as human food. The biggest producers of pine nuts are China, Russia, North Korea, Pakistan and Afghanistan.
The pinyon or piñon pine group grows in southwestern North America, especially in New Mexico, Colorado, Arizona, and Utah. The trees yield edible nuts, which are a staple food of Native Americans, and widely eaten as a snack and as an ingredient in New Mexican cuisine. The name comes from the Spanish pino piñonero, a name used for both the American varieties and the stone pine common in Spain, which also produces edible nuts typical of Mediterranean cuisine. Harvesting techniques of the prehistoric American Indians are still used today to collect the pinyon seeds for personal use or for commercialization. The pinyon nut or seed is high in fats and calories. In the western United States, pinyon pines are often found in pinyon–juniper woodlands.
Araucaria bidwillii, commonly known as the bunya pine, banya or bunya-bunya, is a large evergreen coniferous tree in the family Araucariaceae which is endemic to Australia. Its natural range is southeast Queensland with two very small, disjunct populations in northeast Queensland's World Heritage listed Wet Tropics. There are many planted specimens on the Atherton Tableland, in New South Wales, and around the Perth metropolitan area, and it has also been widely planted in other parts of the world. They are very tall trees – the tallest living individual is in Bunya Mountains National Park and was reported by Robert Van Pelt in January 2003 to be 51.5 m (169 ft) in height.
Pinus sabiniana, with vernacular names including towani pine, foothill pine, gray pine, bull pine, and digger pine, is a pine endemic to California in the United States. Some sources discourage using the name "digger pine," considering it pejorative.
The northern nutcracker, previously known as spotted nutcracker and Eurasian nutcracker, is a passerine bird in the crow family Corvidae. It is slightly larger than the Eurasian jay but has a much larger bill and a slimmer looking head without any crest. The feathering over its body is predominantly chocolate brown with distinct white spots and streaks. The wings and upper tail are virtually black with a greenish-blue gloss.
Pinus densiflora, also called the Japanese red pine, the Japanese pine, or Korean red pine, is a species of pine tree native to East Asia and Siberia. In China, the plant is known as 赤松.
Jack pine, also known as grey pine or scrub pine, is a North American pine.
The stone pine, botanical name Pinus pinea, also known as the Italian stone pine, Mediterranean stone pine, umbrella pine and parasol pine, is a tree from the pine family (Pinaceae). The tree is native to the Mediterranean region, occurring in Southern Europe and the Levant. The species was introduced into North Africa millennia ago, and is also naturalized in the Canary Islands, South Africa and New South Wales.
Pinus longaeva is a long-living species of bristlecone pine tree found in the higher mountains of California, Nevada, and Utah. Methuselah is a bristlecone pine that is 4,856 years old and has been credited as the oldest known living non-clonal organism on Earth. To protect it, the exact location of this tree is kept secret. In 1987, the bristlecone pine was designated one of Nevada's state trees.
Pinus monophylla, the single-leaf pinyon, is a pine in the pinyon pine group, native to North America. The range is in southernmost Idaho, western Utah, Arizona, southwest New Mexico, Nevada, eastern and southern California and northern Baja California.
Pinus gerardiana, commonly known as the chilghoza pine or neja, is a pine native to the northwestern Himalayas in Afghanistan, northern Pakistan, Waziristan and northwestern India, growing at elevations of 1,800–3,350 metres (5,910–10,990 ft). It often occurs in association with Cedrus deodara, and Pinus wallichiana.
Pinus armandii, the Armand pine or Chinese white pine, is a species of pine native to China, occurring from southern Shanxi west to southern Gansu and south to Yunnan, with outlying populations in Anhui. It grows at altitudes of 2200–3000 m in Taiwan, and it also extends a short distance into northern Burma. In Chinese it is known as "Mount Hua pine" (华山松).
Pinus bungeana, also known by the common names Bunge's pine, lacebark pine and white-barked pine, is a pine tree native to northeastern and central China. It is a slow-growing tree that can grow to heights of 15–25 metres (49–82 ft) is frost hardy down to below −26 °C (−15 °F). Its smooth, grey-green bark gradually sheds in round scales to reveal patches of pale yellow, which turn olive-brown, red and purple on exposure to light.
Araucaria angustifolia, the Paraná pine, Brazilian pine or candelabra tree, is a critically endangered species in the conifer genus Araucaria. Although the common names in various languages refer to the species as a "pine", it does not belong in the genus Pinus.
Pinus henryi, or Henry's pine, is a species of conifer in the family Pinaceae.
Conifer nuts are the edible seeds of conifers, which includes most notably pine nuts and Araucaria nuts.
