Summary:

Oriental hornbeam (Carpinus orientalis Miller) is one of the two endemic species of Carpinus genus in Turkey. Origin based variations of seed, leaf, pericarp characteristics and some morphological characteristics of 1+0 year old seedlings were studied for Oriental hornbeam. Also, variations caused by different seed collection period and effects of pre-treatments on germination were investigated. Seed length and width, seed size, 1000 seed weight, seed fullness ratio, leaf length and width, leaf area, specific leaf area, pericarp length, width and area, and seedling length and root collar diamtere of 1+0 year old seedlings measurements were made on collected seeds and seedlings to determine morphological characteristics.

The highest germination percent was observed in tree no: 22nd (%58,5) of 1st population while the lowest germination percent was tree no: 13 (% 0,5) of 3rd population. Between pre-treatments the highest germination percent on 1st population was “citric acid (5000)”, for 2nd population “GA3 (500 ppm)” showed the highest germination percent and for 3rd population the highest germination precent was observed in “two months of cold stratificatıon + GA3 (500 ppm)” pre-treatments. Variance analysis (ANOVA) showed genetical varitation between populations and within populations. Also, in order to determine similar groups Duncan test were made on between and within populations.
