The differences among populations in scots pine (Pinus silvestris L.) seed stands of western Black Sea region

III THE DIFFERENCES AMONG POPULATIONS IN SCOTS PINE (Pinus süvestris L.) SEED STANDS OF WESTERN BLACK SEA REGION (M.Sc Thesis) Hakan ŞEVİK GAZI UNIVERSITY INSTITUTE OF SCIENCE AND TECHNOLOGY February 2005 ABSTRACT The aim of this study was determine the differences among some of the the registered seed stands in the l'st breeding zone by means of the morphological characters. 18 morphological characters were designated by measuring and observing on seed, seedling and sampling concerning to the 9 seed stands in the l'st breeding zone. The obtained data was analysed by variance, cluster and penrose analys. In this way, both the determination of the closeness and remoteness among the seed stands and the investigation of the results of the different analysis methods applied to the same data were evaluated. In conclusion, It was determined that the different analysis methods applied to the same data were supported to each other sometimes. Sometimes, the different methods were in conradiction with the others and this caused inconsistency. In respect of the cluster analysis, Akyaza-Dokurcun seed stand was determined as the most different seed stand in the studied stands. The most remote seed stands were determined as Akyazi-Dokurcun and Beypazarı-Eğriova according to the penrose analysis.IV Science code Key Words Page number Thesis Advisor : 502.01.02 : Scots pine, Morphologic character, seed stand :60 : Asist Prof. Sezgin AYAN
