The effects of different pot length and growing media on seedling quality of Crimean juniper (Juniperus excelsa Bieb.)

The aim of this study was to determine appropriate pot length and growing medium for Crimean Juniper seedlings (Juniperus excelsa Bieb.), which will be used for afforestation of extreme areas. For this purpose, polyethylene pots of 11 cm width and 20, 25 and 30 cm lengths were used. As growing medium, 13 different treatments were used, containing different ratios of forest soil, pumice, creek sand and humus collected from the species’ natural forest environments. The experimental design was a randomized block with 3 replications under open field conditions. Some morphological properties of the seedlings, such as seedling height, root collar diameter, shoot and root fresh and dry weights and shoot/root ratios (fresh and dry weights) were measured on 1 + 0 year old seedlings. Statistical analyses indicated that when pot length increased, the seedling quality improved. The seedlings with the best quality in terms of the measured criteria can be grown in 11 cm x 30 cm pots. In respect to the growing media, 70% forest soil + 15% humus + 15% pumice or creek sand should be used

Determination of Bioactive Compounds and Mineral Contents of Seedless Parts and Seeds of Grapes

In this study, phenolic compounds, minerals, total flavonoids, total phenolic contents and antioxidant activities of the seedless parts (pulp+skin) and seeds of table and wine grapes were determined. Also, the total oil, tocopherol contents and fatty acid composition of seed oils of table and wine grapes were investigated. The highest total phenolic content of the grape pulp was found in Trakya ilkeren (199.063mg/100 g), while total flavonoid and antioxidant activity of the pulp was determined at a high level in Red Globe (6.810 mg/g, 90.948%). Antioxidant activity, and the total phenolic and flavonoid contents of grape seeds varied between 86.688 and 90.974%, 421.563 and 490.625 mg GAE/100 g, and 90.595 and 145.595 mg/g respectively (p < 0.05). Generally, the main phenolic compounds of all grape pulps and seeds were gallic acid, 3,4- dihydroxybenzoic acid, (+)-catechin and 1,2-dihydroxybenzene. In addition, the oil contents of grape seeds ranged from 5.275 (Çavuş) to 13.881% (Çınarlı karası) (p < 0.05). The major fatty acids of grape seed oils were linoleic, oleic and palmitic acid. The seed oil of the Trakya ilkeren variety was rich in tocopherols in comparison with the other varieties. The major minerals of both the seedless parts and the seeds were determined as K, Ca, P, S, Mg

Spoligotyping of M. tuberculosis strains from cattle in Turkey [Türkiye’de sığırlardan İzole edilen M. tuberculosis suşlarının spoligotiplendirmesi]

Although it is generally accepted that M. Bovis leads to tuberculosis in cattle, there are statements given from the different regions of the world, referring to the fact that M. tuberculosis, which is known as the human tuberculosis agent, causes tuberculosis in cattle as well. The material of the study consisted of 13 M. tuberculosis isolates which were isolated and identified from the organ pieces of 95 cattle with the culture methods; these organ pieces had been taken from the cattle with granulomatous lesion detection after the slaughtering in slaughterhouses located in Çukurova region and brought to the laboratory under sterile conditions. It was determined in the genotyping conducted by using the Spoligotyping method that 13 of the 55 isolates were M. tuberculosis and they belonged to the T1 family (SIT53) by becoming dense in one cluster (100%). Consequently, it was shown with this study that M. tuberculosis, which leads to tuberculosis in humans, could be transmitted from humans to animals and from animals to humans again, and researching the human and epidemiological tuberculosis cases by using molecular epidemiology-based methods such as spoligotyping might provide useful information about explaining the ways of transmission of tuberculosis. © 2015, Veteriner Fakultesi Dergisi.
