Chemical Composition and Antibacterial Activities of Juniperus Horizontalis Essential Oil
(Canadian Science Publishing, Nrc Research Press, 2014) Eryigit, T.; Okut, N.; Ekici, K.; Yildirim, B.
In recent years, the screening of antibacterial activity has been the subject of much research, and the antibacterial activity of essential oils could be a promising subject for future investigation. In this study, the antibacterial activities of Juniperus horizontalis essential oils and their components were investigated. Essential oils were isolated using the hydro-distillation method and their components were analyzed by gas chromatography-mass spectrometry (GC-MS). The main compounds found in the oil of leaves were linalool (33.76%), P-cymene (23.20%), gamma-terpinene (8.67%), trans-sabinene hydrate (8.59%), thyme camphor (8.49%), carvol (5.08%) and borneol (4.22%). Juniperus horizontalis essential oils were evaluated for antibacterial activity against six bacterial strains using the disc diffusion method. The results indicate that the essential oil of J. horizontalis shows variable and significant antibacterial activities against the six tested bacteria species. The diameters of the inhibition zones formed for bacteria were measured. The lowest inhibition zone was 12 mm (sensitive) against Pseudomonas aeruginosa ATCC 10145 and the highest zone was 32 mm (extremely sensitive) against Enterococcus faecalis ATCC 29212.

Screening of Different Nitrogen Rates and Intra-Row Spacing Effects on Yield and Yield Components of Safflower (Carthamus Tinctorius L.) Under Microclimate Conditions, Igdir Plain, Turkey
(Canadian Science Publishing, Nrc Research Press, 2015) Eryigit, T.; Akis, R.; Kaya, A. R.
The yield of safflower (Carthamus tinctorius L.) is affected by many factors, among which nitrogen fertilization and plant density are significant. This study was conducted as a split plot in a randomized complete block design arrangement with four replications, during the successive seasons 2011 and 2012, to determine the effects of nitrogen application rate and intra-row spacing on the growth, yield and yield components of safflower under the ecological conditions of the Igdir Plain, Turkey. The main plots were three intra-row spacing (IRS1, IRS2 and IRS3) and subplots were four nitrogen rates (N-1, N-2, N-3 and N-4). Intra-row spacing had significant effects on all parameters except plant height and seed oil content. There were significant effects of fertilizer rate on all parameters except seed oil content. The interaction of nitrogen rate and years had significant effects on seed yield. Correlations showed significant negative results between 1000-seed weight and seed oil content (-0.217). However, there was a high seed yield in 2011 compared with 2012. Among intra-rows, IRS2 and IRS3 gave greater yield compared with IRS1, while N-3 gave a higher yield than other N rates (0, 100, 150, 200 kg ha(-1)) in both years of the study, especially 2011.
