چکیده :

Turpentine tree or wild pistachio (Pistacia atlantica Desf. ) belongs to the Anacardiaceae family. This tree likes drought and grows well in hot and dry areas. The fruit of this tree is an oily seed, hard, small and round, and its ripe green color. Beneh seed oil is used for medicinal and edible purposes. The resinous compounds extracted from the trunk of the baneh tree called turpentine have significant industrial value. Beneh oil has a lot of saturated and unsaturated fatty acids and terpenoids and sesquiterpenes, which has made it one of the best edible oils. Propagation of baneh is done through seed cultivation, but the existence of mechanical and physiological stagnation is one of the inhibiting factors of seed germination in this plant, which causes a decrease in the percentage and speed of seed germination. This experiment is to overcome the mechanical and physiological stagnation of the baneh seed in a factorial way in the form of a completely random basic design in four replications with four factors including: scratching on two levels (without scratching and treatment with 70% sulfuric acid), cooling in three levels (without cold treatment, wet cooling at 4 degrees Celsius and dry cooling at -20 degrees Celsius), potassium nitrate at three levels (zero, one and two percent) and gibberellic acid at two levels (zero and 50 mg per liter) was done. The results showed that the simultaneous application of three treatments of seed scraping with 70% sulfuric acid, wet chilling and gibberellic acid have the greatest effect on breaking seed stagnation, followed by an increase in the percentage and rate of germination of cotyledon seeds, as well as the initial growth of seedlings.
