This research was carried out in the Forest Department's nursery at the University of Mosul's College of Agriculture and Forestry, as well as in a green house, to investigate the effect of collecting pine (Pinus brutia Ten.) seeds from three regions in northern Iraq: Mosul (Nineveh Governorate), Zawita (Dohuk Governorate), and Koysinjak (Erbil Governorate) on the effect of soaking the seeds. The seeds were planted in the spring of 2018, the experiment lasted two years, and the results were obtained in the fall of 2019, using the correct full form of RCBD. The study's findings showed that there are major variations between the treatments, with seeds collected from Zawita and Koysinjaq area giving the best significant results in germination percentage and other seedling growth characteristics compared to seeds collected from Mosul, and soaking with humic acid giving the best results in germination percentage and other seedling growth characteristics.
