Abstract:
In the present study phenological properties of six endemic taxa which occurred under a Pinus nigra Arn. subsp. pallasiana Holmboe forest at Kirklar Mountain, Amasya were examined. Phenological life cycles of geophytic species were completed lower temperatures as compared to the other species. Vegetative growth was begun between 0.2-3.5°C and flowers and fruits were beared at 1.1 and 4.6°C, respectively in microthermic species. At the onset of vegetative growth temperature was 4.6°C in mesothermic species. The appearance of flowering and fruits were took place at 18.2-20.8°C and leaf abscission and dormancy was took place at 20.7-20.8°C in mesothermic species. Flowering is occurred in heliophilous species at the first half of May and June which daylight period was longer. However, flowering period of sciophilous species was February and March, respectively. Fruit ripening was followed similar pattern to flowering. Some significant correlations were found between the different climatic parameters and the number of fruits and flowers. Negative correlations were found between relative humidity and the number of flowers and fruits in all species and they were statistically significant. Mostly positive correlations were found between daylight hours and the number of flowers and fruits and most of them were not statistically significant.
