Abstract :In this study, the germination and seedling percent of Crimean Juniper (Juniperus excelsa Bieb.) seeds which were classified into eight classes according to their colours (IA: light-coloured and IB: darkcoloured seeds), morphological appearance (IIA: large-sized and IIB: small-sized seeds), floating ability in saccharine solution (IIIA: floated and IIIB: sunken seeds) and water (IVA: floated and IVB: sunken seeds) were investigated. The seeds were sown to germinate in open-field conditions with sowing Enso-potray of 45x35 cm in size, and the experimental design was “Completely Randomised Design” with three replications. Germination data on seed classes were analyzed using SSPS statistical software. Analysis of variance and Duncan test showed that the highest germination percent (51.3%) was provided by dark-coloured (IB) seeds. In conclusion, as it is easy to practice and economical method for production of Crimean Juniper Seedlings in forest nurseries, the seeds could be classified by floating process in water. It could be said that the germination ability of the floated seeds in water are much better than those of the sunken seeds.
