Sakhalin fir (Abies sachalinensis)

Description
Habit

Evergreen tree 25-30 m high (occassionally to 40 m) and 50-70 cm diameter. Ovoid conic crown, densely branched (Bobrov, 1978).

Bark

Dark-greyish bark tinged with green and numerous resinous blisters, old trees with ash-grey or dark-grey bark with lengthwise shakes.

Yellowish-brown inversely wedge-shaped, 4.5-6 mm in length, and 2.5-3.0 mm wide with wing 6-7 mm.

Root system

Development of root system depends on soil-ground conditions: on loam moist soils A. sachalinensis forms surface root system, on deep drained soils it forms a root system with a well developed tap root.

Phenology

A. sachalinensis has a fairly typical Far Eastern phenological rhythm, which is characterised by early beginning of vegetation period. However, phenological phases vary with conditions. According to phenological data (Takatoi, 1950; Kartashov et al., 1984; Funakoshi, 1985): opening of growth buds - late May; start of leaf flushing - early June; full leaf flushing - mid- to late June; differentiation of flower buds - July or August; winter terminal bud formation - late July; pollination - mid-June; flowering - end of May to mid-June. Scattering of cones in late September to October. Abundant seed crops occur every 3-4 years.
