The Effect of Altitude on Seedling Quality Characteristics of Common Hornbeam and Oriental Hornbeam

This study aims to determine some morphological characteristics of two-year-old common hornbeam (Carpinus betulus L.) and oriental orientalis Mill.) seedling the quality classes seedlings according Turkish Standards Institute’s (TSI) standards sturdiness quotient values. As a material, seedlings, grown from seed obtained three different altitudes as lower (0-400 m), mid (400-800 m) upper (800-1200 in Trabzon-Maçka watershed were used. The seedbeds open nursery conditions Karadeniz Technical University Forestry Faculty Research Application Greenhouse. Seedling length root collar diameter measured seedlings. was calculated with data characteristics. Quality classified TSI determined for highest mean 48.76 cm at 3rd altitude level, while found 38.90 2nd level. diameters varied between 4.97-5.23 mm 4.62-5.09 hornbeam. result variance analysis, statistically significant differences (p
