Abstract :Scotch pine is a primary species that spreads from sea level to very high altitudes in Turkey and has a very wide distribution area in the world. For this reason, it is important to investigate the variations of the species depending on the altitude. The research aims to determine the morphogenetic variations of the seedling characters in populations representing the vertical distribution area of Scotch pine and to reveal the within and among population variations in the vertical distribution areas. In the study, seedlings insert ignore into journalissuearticles values(three, four and five-year-old); grown from the seeds collected from five populations in the altitudinal zones up to 2,250 m from sea level in the natural distribution area of Scotch pine in Trabzon region were used. The seedling’s height, root collar diameter, the number of side branches and crown buds and sturdiness quotient were determined. As a result of the study, it was determined that there were statistically significant differences insert ignore into journalissuearticles values(p<0.01); among populations in different altitude zones. The average seedling heights increase in the transition from the 4th altitude zone to the 5th altitude zone in Zigana, while the height of the seedlings decreases in all three growth periods due to the increase in altitude in general. Also, in the transition from the 2nd elevation zone in Maçka to the 3rd elevation zone in Zigana, the mean root collar diameters increased. On the other hand, in seedlings at altitudes other than these, the root collar diameter averages decreased as the altitude increased.
