Doğu Ladini (Picea orientalis) kozalak ve tohum özelliklerindeki coğrafi farklılıklar

The aim of this study is to investigate the geographic variations of some cone and seed characteristics of oriental spruce (Picea orientalis). Fort this purpose, the cones were collected from 33 sampling plots within the species natural distribution in Artvin and Posof (Ardahan). Cone length and diameter, 1000-seed weight, seed length and diameter, height of seed wing and number of seeds in a cone were determined. Geographical features such as altitude, aspect, and distance to the Black Sea, longitude and latitude of the sample plots were recorded. According to the analysis of correlation, the negative correlations were defined between the altitude of sampling points and cone length and diameter. In addition to this, there were negative correlations between the distance to the Black Sea and cone diameter, seed diameter and 1000-seed weight (p<0.05).
