Abstract
Seed and seedling characteristics, including one thousand seed weight, germination period, germination percentage, epycotyl length, hypocotyl length, cotyledon length and cotyledon diameter, were studied in three narrow-leaved ash (Fraxinus angustifolia Vahl.) provenances in the present study. One thousand seed weight, germination period and germination percentage were 85.8 gr, 25 days and 48.2 % while epycotyl length, hypocotyl length, cotyledon length and cotyledon diameter were 31 mm, 10 mm, 27 mm and 16 mm, respectively. There were significant differences for germination percentage, epycotyl length, hypocotyl length and cotyledon diameter among the provenances according to the results of analysis of variance The results of the study should be used in nursery practice and breeding of the species such as sowing density, selection of seed stands.

Özet
Bu araştırmada, dar yapraklı dişbudak (Fraxinus angustifolia Vahl.) orijinlerinde, tohum ve fidecik özelliklerinden, tohum bin tane ağırlığı, çimlenme süresi, çimlenme yüzdesi; epikotil boyu, hipokotil boyu, kotiledon boyu ve kotiledon eni çalışılmıştır. Çalışma sonucunda dar yapraklı dişbudakta ortalama, bin tane ağırlığı 85,8 gr, çimlenme süresi 25 gün, çimlenme yüzdesi 48,2; kotiledon boyu 31 mm, kotiledon eni 10 mm, epikotil boyu 27 mm ve hipokotil boyu 16 mm olarak bulunmuştur. Uygulanan varyans analizi sonucunda, orijinler arasında çimlenme yüzdesi, kotiledon eni, hipokotil boyu ve epikotil boyu bakımdan anlamlı fark olduğu belirlenmiştir. Çalışma sonuçları, türün fidanlık tekniği ve ıslah çalışmaları bakımından önemlidir. Anahtar kelimeler: Dişbudak, Tohum, Epikotil, Hipokotil, Kotiledon
