	Pedunculate oak - Wikipedia, the free encyclopedia
		The Pedunculate Oak or English Oak (Quercus robur) is native to most of Europe, and to Asia Minor to the Caucasus, and also to parts of North Africa.
		It is the type species of the genus (the species by which the oak genus Quercus is defined), and a member of the white oak section Quercus subgenus Quercus section Quercus.
		Pedunculate Oak is distinguished from this species by its leaves having only a very short stalk 3–8 mm long, and by its pendunculate acorns.

	Trees for Life - Species Profile: Oak
		About 450 species of oak have been described worldwide, of which 25 are native to Europe, but only sessile and pedunculate oak have such a broad distribution, and they are the sole species native to the north and west of the continent.
		Both species of oak are distributed throughout much of Scotland at lower elevations, usually less than 300 metres, although pedunculate oak is more common in the south and east of the country and sessile oak predominates in the north and west.
		Oaks are deciduous trees, and in winter their buds are distinctive by being clustered at the end of the twigs.

		This oak, the 'king of trees' has a special place in the English psyche, and is a well-loved symbol of strength and duration (4).
		The pedunculate oak is the dominant tree of deciduous woods in Britain, it occurs in coppice woodland, high forest and ancient wood pastureland, and has often been planted in hedgerows.
		Upland oak woodlands have declined by 30-40% over the last 60 years as a result of re-planting with conifers, conversion to grazing land, overgrazing by sheep and deer, and unsuitable management (8).

		Oak made excellent charcoal, and in the north of Britain the smelters' furnaces were fed by charcoal from the sessile or durmast oak (Quercus petraea), which tolerates the more acid, less fertile soils of the region.
		The huge quantities of oak required for charcoal exceeded the supply of this slow-growing tree, and by the 17th century large tracts of the Scottish countryside had been stripped of its oaks by greedy lairds eager to cash in on their value to the smelters.

	Mycorrhiza Literature Exchange
		Pedunculate oak (Quercus robur L.) was germinated and grown at ambient CO2 concentration and 650 mu mol mol(-1) CO2 in the presence and absence of the ectomycorrhizal fungus Laccaria laccata for a total of 22 weeks under non-limiting nutrient conditions.
		Allocation of reduced sulphur from oak leaves was studied by flap-feeding radiolabelled GSH to mature oak leaves.
		From these experiments it can be concluded that, in mycorrhizal oak trees grown at elevated CO2, the transport of sulphate to the shoot is increased at the level of xylem loading to enable increased sulphate reduction in the leaves.
