This work consists on the analysis of germinatión and evaluatión of pregerminative treatments (scarification and depth seeding methods)on seeds of Pinus arizonica and Pinus durangensis collected from the northwest region of the Méxican State of Durango. On the Pinus arizonica, the seeds submerged in oxygenated water at 3 % for 12 hours, to, cause the greater germination of seeds. (96.7 %), meantime of the Pinus durangensis the greater germinataion (85.5 %) of obtain without scarification the seeds. For both species, seeds submerged in boiling water of 30 seconds presented the least germination rate. For both species, the greatest germination rate was obtained at depths of 1.0 and 1.5 cm, with a germination rate of 97 and 89 % in Pinus arizonica and Pinus durangensis, respectively. So the lowest germination rate was obtained at a depth of 3.0 cm.Keyworks: Scarificatión, depth seeding, plantulae.
