The effects of different scotch pine (Pinus sylvestris L.) seed origin to cone and seed characteristics

This study was carried out for determing the effects of different seed sources on cone and seed traits by collecting the cones from Çankırı- Ilgaz seed stand and Eskisehir-Mihalıçcık clonal seed orchard. A total of 1200 cone samples were collected from 30 dominant trees (20 each) at Ilgaz-Uzundag (Number of seed stand is 176) and 30 choosen trees (20 each) representing the clones at Mihalıçcık-Ormantepe (Number of clonal seed orchard is 96) in the rich seed year (2004) for the investigation. The morphologic characteristics of cones, seeds and wings such us the diameter, height, carpel number, weight of each cone and diameter, height, number, weight of each seed derived from each cones and diameters, heights, colours of wings were determined. The average values of cones picked up from Ilgaz seed stand and Mihalıçcık clonal seed orchard were found respectively; Kzç: 23,81 mm and 22,11 mm, Kzb: 47,92 mm and 41,87 mm, Kzag: 11,27 gr and 7,48 gr, Kps: 58,87 pieces and 67,07 pieces, and the average values of seeds vii were found respectively; Ths: 30,18 pieces and 27,96 pieces, Thç: 2,83 mm and 2,73 mm, Thb: 5,13 mm and 4,79 mm, Thag: 0,310 gr and 0,180 gr, BrThag: 0,01 gr and 0,006 gr, Knç: 5,82 mm and 5,30 mm, Knb: 18,56 mm and 16,6 mm. All values were found higher at samples picked up from Ilgaz seed stand than samples picked up from Mihalıçcık clonal seed orchard except Kps. Key Words : Scotch pine, Cone, Seed, Seed Origin
