Head cones were a form of solid perfume, containing myrrh, that were presumably made of a mixture of oils, resins and fat. Images of the era show people wearing them on wigs or on shaved heads. The slow melting of the cones due to bodily heat would have spread the fragrance. [3]
Stone pine cones in South Tyrol. To produce pine liqueur, the red pine cones are collected at the end of June, mid-July, while they are still in full sap, before they're woody. The harvest is often labor-intensive, as the pine cones can only be hand-picked when allowed (the trees are often located in natural protection areas, where cone ...
Pine oil is a higher boiling fraction from turpentine. Both synthetic and natural pine oil consists mainly of α-terpineol, a C10 alcohol (b.p. 214–217 °C). [5] [1] Other components include dipentene and pinene. [6] The detailed composition of natural pine oil depends on many factors, such as the species of the host plant. [7]
The cones thus grow over a two-year (26-month) cycle, so that newer green and older, seed-bearing or open brown cones are on the tree at the same time. Open cone with empty pine nuts The seed cones open to 6–9 cm ( 2 + 1 ⁄ 4 – 3 + 1 ⁄ 2 in) broad when mature, holding the seeds on the scales after opening.
On the coast, the knobcone pine may hybridize with bishop pine (Pinus muricata), and Monterey pine (Pinus radiata). In the western foothills of the Sierra Nevada, knobcone pine is often a co-dominant with blue oak (Quercus douglasii). [7] The species is susceptible to fire, but this melts the cone resin, releasing seeds for regrowth. [4]
A mature female big-cone pine (Pinus coulteri) cone, the heaviest pine cone A young female cone on a Norway spruce (Picea abies) Immature male cones of Swiss pine (Pinus cembra) A conifer cone, or in formal botanical usage a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads.
In old-growth pine, the heartwood of the bole is often saturated in the same way. When boards are cut from the fat lighter wood, they are very heavy and will not rot, but buildings constructed of them are quite flammable and make extremely hot fires. The seeds of the longleaf pine are edible raw or roasted. [29]
