Abstract
Taurus fir (Abies cilicica /Ant. et Kotschy/ Carriére) is a tree species mostly found in the Taurus mountains in Turkey. The objective of this study was to determine the morphological and physiological characteristics of the seed of the Taurus fir. The seeds were collected from five different provenances of natural distribution, including Göksun, Saimbeyli, Kozan, Anamur, and Bucak. In the laboratory, for each of the different provenances, we measured the1000-seed weight; the length, width, and thickness of the seeds; and the weights of the individual seeds. The morphological characteristics of the seeds varied according to their provenances. To determine the necessary duration of pre-chilling, we attempted to germinate the seeds from each of the five different provenances, after pre-chilling at 4 °C for 0, 2, 4, and 6 weeks. We determined that the optimum pre-chilling duration was six weeks. In order to determine the optimum germination temperature, the seeds from three provenances were subjected to a germination test at each of four different temperatures (12, 16, 20, and 24 °C) after three different pre-chilling durations (2, 4, and 6 weeks). This resulted in various germination rates and speeds. The seeds germinated best at 20 °C and 24 °C.
