Abies firma Japanese fir seeds
LATIN NAME: ABIES FIRMA
COMMON NAME: Japanese Fir
The Japanese fir pillars the tall, evergreen conifer with the dense, stiff, dark-green needles with the pale bands and the deeply furrowed, grey-brown bark, the needles pillaring the broad, conical crown, the large, upright, cylindrical, grey-green cones with the exserted bracts following along the upper branches. The tree grows steadily into the tall, broad crown, and it stands the cold and the warm, humid spells well. It likes the sun, and the deep, moist, well-drained soil.
Scientific Research & Plant Biotechnology
The bracted cones of the Japanese fir give it a recognised place in the research on the warm-temperate Asian firs of the true fir group, and the firma species appears in the studies of the lowland forest growth and the cone bract structure. The work looks at the way the cylindrical cones pillar along the upper branches, the soft, straight timber, and the seed biology. The foresters value the wood, and the growers of the warm-climate specimen conifers keep the species in their catalogues.
Ecological & Economic Value & Wide Applications
In the warm garden, the Japanese fir pillars the warm garden with the broad, conical crown. The upright cones stand along the upper branches, the timber serves the building and the boxes, and the tree makes the fine specimen and the windbreak. It thrives in the deep, moist, well-drained, sunny ground. Bracted-coned, broad and warm-tolerant.
To grow the Japanese Fir from seed, set the seeds into the deep, loamy drills of the open ground in the autumn.
Set the seeds into the deep, loamy drills of the open ground, and give the young trees the open, sunny spot. The pillar form comes over the years. , then cover them lightly, keep the drills gently watered, and the young trees wake over the spring. The pillar form will broaden within a few seasons.
Description Tree to 50 m. tall and 200 cm dbh. Trunk massive, straight, with long branches horizontal or ascending. Crown broadly pyramidal or domed, becoming flat-topped with age. Bark gray, smooth with resin blisters when young, then fissured, corky and darker with age. Branchlets grooved, yellowish-green to gray-brown, glabrous or with fine blackish pubescence. Buds ovoid to conical, to 10 × 5 mm, slightly resinous, with broadly conical scales, grayish-brown, persisting several years. Juvenile leaves bifid, extremely sharp pointed, present at the base of old trees. Leaves pectinate, nearly 2-3 ranked, spreading outwards and upwards, with a distinct V-like parting, grooved above, keeled below, bright dark green above, glaucous-yellow below; stomata usually absent above, in 12-13 lines below; 1.5-3.5 cm long by 2-4 mm. wide, base twisted, apex obtuse, emarginate or notched. Pollen cones cylindrical, yellowish, solitary and pendant in leaf axils, 2.5-3 cm long. Seed cone ovoid-oblong to conical, apex rounded, green with yellow bracts, maturing yellow-brown, 8-15 cm long by 3-5 cm. wide, resinous; bracts erect and slightly exserted, narrow, diamond-shaped. Seed scales 2-2.5 cm long by 2.8-3.2 cm wide, smooth or longitudinally striated. Seed 6-8 mm long, light brown with a 10-15 mm long brownish wing
