Yellow pine 1.4 m
Ecology: Decorative with a dark green crown, long, densely collected needles at the ends of the shoots. Drought-resistant and heat-resistant, light-loving. Grows well on light loamy soils. Does not tolerate damp and heavy soils. In its range it can withstand temperatures down to -40 C. It enters the climatic zone (4 b) in the north-eastern part of its range. Outside its range in Russia it is rare. It deserves wider distribution as a highly decorative crop. Heavy pine has significant intraspecific genetic variability and forms a number of subspecies and forms. In this section we're talking about the typical form of heavy pine and its variety Pinus benthamiana, the characteristics of which are outlined below.
Spreading: homeland - North America, South part Canadian Province of British Columbia in the northern part of the range and in the United States, in the States; Washington, Oregon, Idaho to Western Montana in the east of the range.
A variety of heavy pine (pinus ponderosa ssp. benthamiana) differs from the typical form in the large size of the generative organs, for example; cones up to 15 cm long, with seeds up to 9 cm long and a seed wing up to 2.5 cm, longer and thinner needles up to 25 (30) cm, red pollen, red-brown shoots and highly resinous buds. Can reach 80 m in height and 4 m in trunk diameter.
Macrostrobiles during the dusting period
Spreading: Pinus benthamiana grows in the States, Washington and Oregon in the Coast Range region, in California, where it reaches the coast Pacific Ocean, further to the southeast it rises into the Sierra Nevada mountains to an elevation of 2300 m and reaches the border with Mexico. Benthamian pine grows almost everywhere in warm climates within (7 – 10) climate zone. When introduced, it should be tested in Crimea and the Caucasus.
Megastrobiles of yellow pine in the juvenile phase of development
Seed sources for yellow pine vary geographically. From the seeds collected at these points, seedlings were grown in our nursery.
Seed source No. 1. USA. Montana State, national reserve Kootenay (northwestern part of the state).
Seed source No. 2. Canada, British Columbia. Seed collection in the middle Fraser River region.
Seed source No. 3. USA. State of South Dakota, Black Hills Mountains (yellow pine).
Seed source No. 4. GBS. Queen cell.
A tree 50 meters or more in height, with a narrow-conical, light crown and strong, relatively few, short, outstretched or often arched branches from the middle to the top. The bark is very thick (8–10 cm thick), reddish or dark brown to almost black, coming off in large plates. The shoots are brownish-green, without plaque. The buds are elongated-conical, pointed, up to 1.8 cm long, resinous; their scales are pressed, reddish-brown. The needles are in bunches of 3, sometimes 2 or 5 on the same tree, thick, very dense, protruding and somewhat curved, prickly, dark green, up to 30 cm long and 1.5 mm wide. The vaginas are long, up to 2.2 cm long.
Female spikelets are dark red. Cones are single or 3–5 in whorls, almost sessile and sometimes slightly bent downward, elongated-ovate, 10–15 cm long and 5–6 cm wide, shiny brown, soon opening when ripe. The scutes are slightly swollen, but with a clear transverse carina and several radially diverging folds, widely rounded in front. The navel is raised, dark, with a small straight or downward curved spine that remains. The seeds are dark brown, 7–10 mm long and 5–6 mm wide; the wing is 2.5–3 cm long, with the greatest width in the middle. There are 21.8 thousand seeds in 1 kg.
Motherland: western North America from British Columbia (51°30′), where it grows in the Cascade Mountains, south to southern California, the Coast Mountains and especially the Sierra Nevada. It grows on dry slopes and valleys, at an altitude of 1,400 - 2,600 meters, with sandy and loamy rocky soil. Forms forests pure or together with Pinus Lambertiana, Pseudotsuga taxifolia, Abies concolor and other conifers.
Often divorced in North America- in the eastern states; It is stable in the coastal states up to and including New York State, and in protected locations in Massachusetts. It's freezing in Arnold Arboretum. Introduced into Europe in 1827 and is quite common in Western Europe. Quite stable in Germany, in Sweden up to 60° north latitude, in England; in Ireland it grows poorly, which is obviously explained by the humid climate that is not suitable for it.
In Russia in 1837 it was introduced by Nikitsky Garden. There are several specimens in the garden; the oldest, about 100 years old, with the upper part of the trunk broken by a storm, has a trunk diameter of 67 cm and a height of 10 m.
Grows well, bears fruit abundantly, produces viable seeds; drought-resistant; is affected by scale insects, but tolerates these lesions well. Good specimens are also available on the Black Sea coast of the Caucasus in Sukhumi, as well as in Kislovodsk. In Ukraine, well-growing specimens, 7–8 meters tall, are available in Kyiv, in the Odessa region and in the Veliko-Anadolsky forestry. Growing in Minsk. There is an indication that a small, 75 cm tall, specimen of this pine is available in Nikolsk Vologda region; so far it does not suffer from frost, but so far to the north Pinus ponderosa, apparently, cannot be promoted.
Pinus ponderosa- a drought-resistant tree that grows best in open sunny locations on light loamy soils. Very poorly tolerated wet soils. At first it grows slowly, then its growth becomes more rapid. How decorative tree for parks deserves wide distribution in Ukraine, Crimea, the North Caucasus and Transcaucasia. Beautiful when planted alone and in small groups. Its known form is with long hanging branches (f. pendula Sarg.). Experiments on introducing it into forestry are of interest, since it has high-quality wood, widely used in North America as construction and ornamental timber; wood yellow color, durable, specific gravity 0.4–0.47. The bark contains about 11% tannins. The resin contains 18.5% turpentine.
Yellow pine, or Oregon pine, or heavy pine (lat. Pínus ponderosa) is a plant, a large tree of the genus Pine of the Pinaceae family. It grows naturally in the western regions of North America. Average height adult tree 18-39 m (72 m maximum). The trunk thickness is 80-120 cm in diameter; the trunk is straight. The crown is broadly cone-shaped or rounded. The bark is yellow to red-brown, with deep, irregular fissures that intersect so that the bark appears as rectangular scaly plates. The branches either point downward or spread upward. The branches are strong, up to 2 cm thick, orange-brown, darken and become rough with age. Needles up to 25cm long.
One of the main forest-forming tree species in North America (western states of the USA (Oregon, southern California)) on the cascading coastal rocky mountains, where it grows mixed with other conifers or in pure stands at an altitude of 1400-2600 m. Sun-loving. The requirements for soil and moisture are low; it prefers well-drained sandy or rocky loamy soils. Lives 300-600 years.
Relatively stable in urban environments, more stable than Scots pine, but less stable than black pine. It tolerates the city well in large gardens and parks. This tree feels great in any conditions: it can withstand severe frosts and hot sunny days. What is really dangerous for yellow pine is stagnant water and swampy soil, which can lead to the death of the tree
Very fast growing in good conditions, the owner of highly valuable wood, is very impressive with its airy openwork crown. Large brown cones collected in whorls give the tree a special color. It is a symbol of the state of Montana.
The germination of seeds is low, so they should be sown in bowls with further picking on ridges at the end of May during the spring-summer rains. The first year requires protection from direct sunlight.
