The Kadıncık shrub (Flueggea anatolica) is one of the endemic forest shrub species in Turkey. In this study, the morphological and physiological characteristics of F. anatolica seeds from three provenances (Tarsus, Kozan, Andırın) were investigated. The average 1000-seed weight was 4.9 g. There were significant differences between seeds from the different provenances in terms of their morphological characteristics, with the seeds from the Kozan provenance having the smallest seeds in terms of weight, thickness, and width. The seeds germinated at similarly high rates (90 ± 2%) at 16°C, 20°C, 24°C, and 28°C. However, the germinations occurred earlier at 24°C and 28°C, with 24°C appearing to be the most appropriate germination temperature. The results indicated that F. anatolica seeds have physiological dormancy, requiring approximately 10 weeks of prechilling for dormancy removal and germination. A 4-week warm-incubation period at 24°C prior to the prechilling treatment had only a slight effect on the prechilling duration time required to remove dormancy. Seeds stored in the refrigerator (+4°C) with a 2.7% or 4.0% moisture content conserved their high initial germination rates after one year of storage. The average germination rate of the prechilled seeds redried to an 8% moisture content and stored for one year at 4°C dropped from 92.7% to 63.6%. Basing on the results of this study, the suggested moisture content and storage temperature for storing F. anatolica seeds are 3–8% and 4°C or less, respectively.

The present study was carried out to determine the effect of temperature on the seed germination of Fraxinus ornus subsp. cilicica, an endemic taxa on Taurus Mountains in Southern Turkey. Seeds from the three provenances were collected and prechilled for 16 weeks before the germination tests. Germination tests were conducted at constant temperatures (5, 15, 20, 25°C) and at alternating temperatures (5~15, 5~20, 5~25, 15~25°C). Temperature treatments were effective on germination percentage and mean germination time. The highest and the lowest germinability were obtained at the 5–15°C (73.3%) alternating and 25°C (9.8%) constant temperatures, respectively. Mean germination time greatly differed at various temperature regimes. Germination accelerated with increased constant temperatures while it was relatively similar speed at alternating temperatures used in the tests. Seed sources had also an effect on the final germination percentage.

In this study, both the morphological maturation and germination ability of the Oriental beechnut were investigated two months prior to seed dispersal to find out the appropriate period of ripened beechnut collection. Beechnuts were collected in the seed stand, Dokurcun-Adapazari, on August 21, September 9, and September 25 on trees, and on October 16, 2003, from the ground after the major seed fall. Germination percentages were 18.0%, 80.5%, 92.0%, and 94.7% on August 21, September 9, September 25, and October 16, respectively. Similarly, both beechnut weight and the embryo:beechnut weight ratio significantly increased with time and reached an approximate maximum level at September 25, 2–3 weeks prior to seed dispersal. This outcome indicates that ripened beechnuts can be collected from the trees, 15–20 days prior to major seed dispersal. The study also indicates that ripened Oriental beechnuts have physiological dormancy and need about 8–10 weeks chilling at 3°C for germination.

Background: The aim of this study was to evaluate the styloid process (SP) length in the normal population using multidetector computed tomography (MDCT). Materials and methods: In this study, 160 patients who underwent paranasal MDCT between January 2012 and December 2012 were retrospectively evaluated. The patients were divided into groups according to their age and gender: Group 1 age 31–40 years old, 111 subjects; Group 2 age 41–50 years old, 49 subjects; Group A 98 males; Group B 62 females. The mean SP length was calculated from the mean of 2 measurements. SPs were assessed for their average lengths in different gender and age groups. Student’s t-test was used for the comparison of the mean SP lengths between the groups. Differences were considered to be statistically significant at p < 0.05. Results: The mean SP length on both sides varied from 18 to 51 mm (28.4 ± 5.5) in all the patients. The mean SP length was 27.2 ± 5.2 mm in females and 29.2 ± 5.6 mm in males. There was a statistically significant difference between the mean SP lengths in terms of gender (p < 0.028). The mean SP length was 28.5 ± 5.7 mm in Group 1 and 28.2 ± 5.1 mm in Group 2. There was no statistically significant difference between the mean SP lengths in terms of age (p > 0.718). Conclusions: In conclusion, there is still no consensus on the normal values of SP length. Normal values should be determined according to the geographical regions and ethnic groups for the diagnosis of Eagle’s syndrome. (Folia Morphol 2013; 72, 4: 318–321)

This study was conducted to determine the impact of heat stress on some physiological and endocrine traits in Saanen goats raised under Mediterranean climate conditions. The effects of thermal stress on heart rate (HR), respiration rate (RR) and rectal temperature (RT) on plasma total trii-odothyronine (T3), thyroxine (T4), Cortisol (C), and HSP70 concentrations were evaluated on twenty two Saanen goats of different ages in the second week of April 2013, July 2013, October 2013 and January 2014. Climatic data such as temperature (°C) and relative humidity (%) were recorded from Spring 2013 to Winter 2014. Live body and BCS values were also recorded during this period. The physiological parameters above were measured twice on each experiment day (morning and afternoon) in all seasons. Blood samples were collected in each afternoon of the experiment day to analyze T3, T4 C, and HSP70. All data were analyzed. According to the values of rectal temperature (RT), it was estimated that the goats were under extreme heat stress only in the summer season. The heart rate (HR) values in the winter season for morning and noon periods were found statistically significant (p < 0.05). The average respiratory rate (RR) in the spring season was found significantly lower. On the other hand, the RR for the noon period in the summer was higher than in the fall and winter seasons (p < 0.05). There was a significant difference (p < 0.05) between summer and fall seasons for C values. The highest value (96.62 ng/ml) was obtained in spring, whereas the lowest (60.58 ng/ml) in the fall. T3 levels in the fall and winter were found to be statistically significant (p < 0.05). They were the highest in the winter and spring, and the lowest in fall. T4 and T4/T3 levels in the winter were found to be statistically higher than in other seasons (p < 0.05). The lowest value for T4 was found in the fall and for T4/T3 in summer. Mean HSP70 value in spring was found to be statistically low (p < 0.05). The changes in THI values in different seasons, particularly between mornings and afternoons, indicated that thermal stress was evident, and that the animals became resistant to it eventually. The fluctuations of the C, T3, T4 and HSP70 values were indicators of the animals’ reaction to thermal stress. The THI values in spring, which were between 16 and 18 THI, may be considered within the ideal comfort zone for goats. It was observed that Saanen goats were able to adapt to seasonal weather changes in the environmental conditions of the region.
