Pinus pinaster (maritime pine) profile

Written by Maggie

Pinus pinaster, also called maritime pine or cluster pine, is a plant of Pinus genus in Pinaceae. Pinus pinaster is naturally distributed in Mediterranean coastal areas and has been artificially introduced and cultivated in China.

Pinus pinaster is a light-loving tree that requires a warm and humid climate, but can tolerate dry conditions in summer. The provenances of Pinus pinaster in Portugal and the southern coast of the Mediterranean (especially Algeria and Tunisia) are more susceptible to freezing than the provenances of the Akundine region. As a calcium-hating species, Pinus pinaster is well suited to poor acidic soils but grows most quickly in thick, fertile soil.

Morphological characteristics of Pinus pinaster

Stems

Pinus pinaster is an arboreal tree, reaching a height of 30 meters in its native place; Bark is deep longitudinal lobed, brown; The large branches are sometimes drooping, forming a pinnacle - shaped crown; Branches grow once a year, sometimes more than once; Branchlets are reddish-brown, without white powder; Winter bud are rectangular round, brown, no resin.

Leaf

Needles of Pinus pinaster are a 2-needle bunch, 10-20 cm long, 2 mm in diameter, stout, often twisted, light green; Transverse section semicircle, two to three layers of subcutaneous layer cells, under the epidermis in an inverted triangle discontinuous distribution, 6 resin channels, mesophytic.

Fruit

Cones of Pinus pinaster are large, shortly pedunculate, often concentrated, conic-ovoid or ellipsoid-ovoid, 9 -- 18 cm long, symmetrical or subsymmetrical, species scales late opening when ripe; The scale shield of species scale is strongly raised, light brown, scale umbilical protuberance, extend into spines.

Ecological habits of Pinus pinaster

Pinus pinaster is a light-loving tree that requires a warm and humid climate, but can tolerate dry conditions in summer.

As a calcium-hating species, Pinus pinaster is well suited to poor acidic soils but grows most quickly on thick, fertile soil.

The distribution area of Pinus pinaster

Pinus pinaster is native to the Mediterranean coast. China Jiangsu Nanjing and Hyundai mountain introduced cultivation, growing vigorously, for the development of the future of afforestation tree species.

Pinus Pinaster is distributed in East China, North subtropical deciduous, evergreen broad-leaved mixed forest areas (major cities: Nanjing, Yangzhou, Zhenjiang, Nantong, Changzhou, Wuxi, Suzhou, Hefei, Wuhu, Anqing, Huainan, Xiangfan, Shiyan).

The use of the Pinus pinaster

The role of wood

The wood of Pinus Pinaster is heavy, dark red, and has many uses, such as a pillar, joinery board, saw wood, paper pulp, railway sleeper, telegraph pole, various boards, furniture, wood floor, wall protection, construction, pillar, veneer, etc.

The use of bark

Pinus Pinaster Bark extract "Pycnogenol" has strong beauty, anti-aging and medical effects. There are a variety of "Pycnogenol" products on the market, which are expensive and have very good market value.

Function of resins

Resin production (turpentine): The resin of Pinus Pinaster is the raw material for turpentine production.
