The genotoxicity of tannic acid (TA, tannin) were investigated using chromosome aberration (CA), sister chromatid exchange (SCE), and micronucleus (MN) test systems in human peripheral lymphocytes. Also, the antigenotoxicity TA against known mutagen EMS was also examined. lymphocytes treated with 1.74 × 10−5, 3.49 6.98 10−5 µM for 24- 48-hour treatment periods. For TA, three different concentrations 2.71 EMS. synergically induced CA alone mixture However, did not induce SCE alone, whereas as...

Drought by climate change in East Mediterranean Region will soil temperature and moisture that lead to alter the cycling of biological elements like carbon nitrogen.However, there are few studies show how sensitivity organic matter mineralization and/or can be modified changes these parameters.In order study affect nitrogen mineralization, a laboratory experiment was carried out two depths (0-5 5-15 cm) soils Onobrychis beata Trifolium speciosum being common annual plants Turkey taken from...

Plant secondary compounds can have stimulating effect on C cycling and change its rate in soils. We examined how leaves of bay laurel (Laurus nobilis L.; Lauraceae) 1,8-cineole (CIN), one constituents, affect soil mineralization rate. Leaves samples were taken from Cukurova University Campus (Adana, Turkey) growing naturally under Mediterranean climate conditions. CIN considered as the two forms organic sources. After determining level by gas chromatography-mass spectrometry, soils mixed...

Background: Salt-affected soils occupy wide areas that have ecological importance in semi-arid and arid regions. Excessive amounts of salt adverse effects on soil physical chemical properties also the microbiological processes. The Pinus maritima, pinea, Eucalyptus camaldulensis were found to be under salinity stress present study area. Thus, carbon, nitrogen, phosphorus contents, microbial biomass, carbon mineralization determined sampled from Tarsus-Karabucak Forest Eastern Mediterranean...

Imazamox, is a herbicide intensively used in the peanut field soils of Osmaniye, Turkey with Mediterranean climate conditions. In this study, two types were selected, first not exposed (NE) to Imazamox previously and second treated soil (P). The recommended dose [(RFD), 40 g L -1 active ingredient], 2 × RFD, 4 RFD added NE P soil. microbial activities measured by carbon nitrogen mineralization under different humidity conditions [60% 80% capacity (FC)]. Carbon was determined CO respiration...

Microbial activity can be affected by herbicides when they are introduced in soil. Indaziflam is a herbicide used for weed control vineyards, apple, peach and orange orchards that inhibit cellulose biosynthesis plants (500 g active ingredient/ l). Recommended field dose of (RD) containing (10 ml/ da) its 2 (RD x2), 4 x4), 8 x8) 16 x16) times RD were mixed with loamy soil sampled from Cukurova University Faculty Agriculture Vineyard (Adana, Turkey) this study. These mixtures humidified at 80%...

Background: Soil salinity is a significant problem in arid and semi-arid Mediterranean regions. In this study, the effects of on nitrogen mineralisation Pinus pinaster, pinea Eucalyptus camaldulensis soils from Eastern coasts Turkey were determined. Material Methods: Nitrogen (NH4+ + NO3-) all samples was determined by Parnas-Wagner method over 42 days at 28°C under constant moisture. Results: NO3--N production (mg kg-1) E. soil significantly higher than P. pinaster 11 (P Conclusions: It...

In this study, organic matter mineralization was studied in the Quercus coccifera (Kermes oak, Fagaceae) soils mixed with leaves having high tannin content, Melia azedarach (Neem tree, Meliaceae) and fruits azadirachtin pure azadirachtin. Carbon of all samples determined by CO2 respiration method over 30 days (28oC 80% field capacity). Addition equal (1x) half (1/2x) amounts soil carbon containing both plants to separately increased microbial activity. The increase activity higher 1x added...

Background: Soil samples were taken from a depth of 0-10 cm under the Quercus cerris and Fraxinus excelsior at an altitude 1300-1500 m Kullin site Gulnar-Mersin compared for their pH, CaCOs, nitrogen (N) %, carbon (C) % contents. Balanced soils in natural forest ecosystems are known to be very rich content which increases with latitude that C/N ratio varies greatly between different plant species. We determined values rates Q. F. Gulnar Gezende first time this altitude. Material Methods: A...

The aim of this study was to determine the first effect lead on microbial activity in soil. carried out soil samples from four different radish (Raphanus sativus L. var. radicula, Brassicaceae) fields along highway a district (Kadirli, Osmaniye) Eastern Mediterranean Region, Turkey. After calculation Pb contents, amounts were brought up 50 and 100 mg kg−1 by treatment with Pb(NO 3 ) 2 , for carbon nitrogen mineralization incubated under controlled conditions (28°C, constant moist)....

The objective of this study was to determine the effects sampling time and depth on some soil properties in a natural olive grove. Soil samples were collected at 0–10 cm (S0) 10–20 (S1) depths February, May, August, November between 2013 2015 Cukurova University Campus, Adana, Turkey. determined organic carbon (SOC), total nitrogen (TN), C/N, C mineralization rate (Cmin) under laboratory conditions, aerobic bacteria fungi counts. Effect these more significant than time. SOC, TN, counts, Cmin...

The aim of this study is to investigate C and N mineralization soils with Ceratonia siliqua (Fabaceae) Pinus pinea (Pinaceae) growing on two different parent materials derived from conglomerate marl in the Eastern Mediterranean Region Turkey. Carbon (C) was measured CO2 respiration method at 28°C over 30 days. nitrogen (N) also vitro both under controlled conditions (42 days, 80% field capacity). There were significant differences between for terms carbon ratio (%) all sampling periods...

The environmental risk of Chromium (Cr) pollution is pronounced in soils adjacent to chromate industry.It important investigate the functioning soil microorganisms ecosystems exposed long-term contamination by Cr.The aim this study was determine effects Cr on carbon mineralization soil.The carried out contaminated and uncontaminated with near away from a mine three different districts (Bozluk, Kızılyüksek Yanıkçam) East Mediterranean Region, Turkey.Carbon were determined humidified 80% field...

This study is aimed at determining the characteristics and microbiota of soil upon which some Turkish Colchicum (Colchicaceae) species naturally grows. For this aim rhizosphere samples balansae Planch., triphyllum Kunze variegatum L. were analysed in research. The carbon mineralization rate C. p<0.05 significantly different from that other two soils. In terms nitrogen mineralization, significant difference exists between all three soils (p<0.001). was found to have highest...
