Acacia mangium seeds – 10 Seeds

$1.50

Acacia mangium is a major plantation species in the humid tropical lowlands of Asia. Its success is due to its extremely vigorous growth rate, tolerance of highly acidic, low nutrient soils, ability to grow reasonably well where competition is severe (for example Imperata grasslands), relative freedom from disease, wood properties that make it suitable for a wide range of uses, and ease of establishment in cultivation. Plantations in Indonesia and Malaysia are the resource base for a large pulp and paper industry. Other uses included fuelwood, timber for building and furniture and particle board.

Acacia mangium seeds – 10 Seeds

Acacia mangium is a major plantation species in the humid tropical lowlands of Asia. Its success is due to its extremely vigorous growth rate, tolerance of highly acidic, low nutrient soils, ability to grow reasonably well where competition is severe (for example Imperata grasslands), relative freedom from disease, wood properties that make it suitable for a wide range of uses, and ease of establishment in cultivation. Plantations in Indonesia and Malaysia are the resource base for a large pulp and paper industry. Other uses included fuelwood, timber for building and furniture and particle board.

The natural distribution of Acacia mangium overlaps the warm and hot tropical climatic zones. In these areas the temperatures are high and equable throughout the year, with the mean maximum hottest month at 31-34°C and the mean minimum coolest month at 15-22°C. The mean annual rainfall is 1,500 to 3,000 mm, with summer (January to March) being the wettest period. Brown salwood grows best in well-drained, acidic soils (pH of less than 4.0) of moderate to low fertility. It grows well in areas of disturbance and has the potential to become weedy under certain conditions.

Overview
Brown salwood is normally a large tree, which grows up to 30 m tall, with a straight trunk that can occupy over half the total tree height, and which is sometimes fluted at the base. On adverse sites it may grow as a small tree or large shrub of 7–10 m tall. The pale grey-brown to dark brown bark is rough and longitudinally furrowed. The branchlets are acutely angled and hairless.

The phyllodes (leaf-like petioles) are obliquely narrowly elliptic to elliptic, large (normally 11–27 cm long and 3-10 cm wide), with three or four main longitudinal nerves which merge at their base. The minor nerves strongly cross-connect to form a fine, elongated network between the main nerves.

Flowers
The white to cream flowers are pentamerous (have parts arranged in groups of five) and are loosely aggregated into spikes, which are 5 to 12 cm long.

Fruits
The pods are openly coiled and twisted, or sometimes tightly spirally coiled, 3 to 5.5 mm wide, leathery to sub-woody, and hairless. The black seeds are 3.5–5 x 2–3 mm, and have a small, bright, yellow or orange aril (fleshy growth) at their base.
