Jun. 21—It starts with the cones. They're usually gathered in the wild, from whitebark pine trees several thousand feet above sea level somewhere in the West. The cones get shipped to the U.S ...
In some cases, they will drop their seeds, but in most Pinus serotina, they will persist and hold their seeds. The color of the seed cones and seed scales is red-brown in color. The foliar sheaths measure 0.4 to 0.8 with long bases. The seeds are ovule in shape, being 0.2 and 0.24 in length, and have an angled tip colored a pale brown. [10]
When first extracted from the pine cone, they are covered with a hard shell (seed coat), thin in some species and thick in others. The nutrition is stored in the embryo in the center. Although a nut in the culinary sense, in the botanical sense, pine nuts are seeds; being a gymnosperm, they lack a carpel (fruit) outside.
[citation needed] The cones, which contain the seeds (or nuts), of the Swiss pine are 4 centimetres (1.6 in) to 8 centimetres (3.1 in) long. Cones take 2 years (24 months) to mature. The 8 millimetres (0.31 in) to 12 millimetres (0.47 in) long seeds have only a vestigial wing and are dispersed by spotted nutcrackers. The species is long-lasting ...
The seeds are 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, with a thick shell, with a vestigial 1–2 mm (0.04–0.08 in) wing; the seedlings have 18–24 cotyledons, the highest number reported for any plant. It differs from all other pinyon species in that it has very massive cones and large seeds.
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.
To obtain the resin from the live longleaf pine, pioneers first cut and removed wood exposing a deep cavity, called a box at the base of the tree. Next a medium-sized, V-shaped cut was performed, above the box to start the resin flow into the box. As resin flowed into the box, it was collected and placed in barrels for shipment.
The Pinaceae (/ p ɪ ˈ n eɪ s iː ˌ iː,-s i ˌ aɪ /), or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, piñons, larches, pines and spruces.
