Pine nuts, also called piñón (Spanish:), pinoli (Italian: [piˈnɔːli]), or pignoli, are the edible seeds of pines (family Pinaceae, genus Pinus).According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally [1] owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also ...
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...

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. The seeds are 11–16 mm (7 ⁄ 16 – 5 ⁄ 8 in) long, with a thin shell, a white endosperm, and a vestigial 1–2 mm (1 ⁄ 32 – 3 ⁄ 32 in) wing.
