A study on Reseda lutea L. distributed naturally in West Anatolia in Turkey

Morphology and seed germination of Reseda lutea L. (Resedaceae), which is distributed naturally in Turkey, were investigated. Germination trial was observed at 10, 15, 20, 25, 30, 35 and 40 °C. In laboratory conditions at 25 °C, 87% of the seeds of R. lutea germinated, while in soil conditions, the best germination rate was only 23%, achieved with seeds sowed at 10 mm depth. The results of germination under different light conditions showed that the germination rate at 25 °C in continuous darkness was 87%, 76% with 6 hours of light, 67% with 12 hours of light, 52% with 18 hours of light and 42% with continuous light. Measurements of samples collected from different localities showed that the length of the plant is inversely proportional to the altitude

A study of the soil-plant interactions of Pistacia lentiscus L. distributed in the western Anatolian part of Turkey

This study was undertaken with the aim of illuminating the soil-plant interactions of Pistacia lentiscus L., which is a Mediterranean sclerophylleous coastal zone plant in the Western Anatolian part of Turkey. The soil analysis data showed that this plant grows on different kinds of soils such as sandy-clayey-loam, clayey-loam, sandy-loam and loamy texture. Soils are not saline, with pH moderately and slightly alkaline. This species prefers soils with low phosphorus and potassium contents, but with different calcium carbonate and nitrogen contents. Three negative linear correlations were observed between plant calcium and soil pH, plant nitrogen and soil calcium carbonate, plant potassium and soil calcium carbonate

Determination of trace elements in the plants of Mt. Bozdag, Izmir, Turkey

The aim of this study was to determine the current level of atmospheric heavy metal content on the Bozdag Mountain of the Aegean Region, Turkey. Twenty nine different plants were selected to study their potential as biomonitors of trace elements such as Ni, Zn, Fe, Pb, Mn and Cd (μg g-1, dry weight). The samples were collected from two different altitudes of Mt. Bozdag. The concentrations of trace elements were determined by atomic absorption spectrometry. The mean concentrations determined at 1000 m altitude ranged from 0.025 to 1.609, 0.232 to 0.731, 0.578 to 5.983, 0.287 to 0.565 and 0.176 to 2.659 (μg g-1, dry weight), for Ni, Zn, Fe, Pb and Mn, respectively. At the altitude of 1600 m, the values ranged from 0.023 to 0.939, 0.258 to 1.254, 0.839 to 5.176, 0.301 to 1.341 and 0.405 to 3.351 (μg g-1, dry weight) for Ni, Zn, Fe, Pb and Mn, respectively. No Cd was detected at either altitude. Statistical significance was determined by the independent sample t-test and comparisons were made in order to determine if there were any differences between the averages of herbaceous and woody plants.

Studija o biljkama uz rub cesta (Zapadna Anatolija, Turska)

In this study, roadside plants distributed throughout the link roads of all the cities in West Anatolia in Turkey were investigated. The length of the selected 17 roads is around 2700 km. The total number of samples collected from the study area is 271 taxa belonging to 57 families. Among them, Asteraceae, Fabaceae, Poaceae are the families that have the largest number of taxa, and Bromus L., Rumex L. and Silene L. are the genera that have the largest number of taxa. The most frequently found taxon throughout the selected roads is Valerianella coronata (L.) DC. and therophytes are the most frequently found life form.Istraživane su biljke uz rub svih cesta koje povezuju gradove u Zapadnoj Anatoliji u Turskoj. Duljina 17 izabranih cesta je iznosila oko 2700 km. Prikupljeni uzorci pripadali su 271 svojti, odnosno 57 biljnih porodica. Među njima su najzastupljenije bile porodice Asteraceae, Fabaceae i Poaceae, a među rodovima to su bili Bromus L., Rumex L. i Silene L. Najčešće nađena svojta uz istraživane ceste bila je Valerianella coronata (L.) DC., a najčešći biljni oblik su bili terofiti

JOURNAL OF ENVIRONMENTAL BIOLOGY

The West Anatolian Region is one of the most important areas for industrialization, population density and traffic in Turkey. Therefore, the leaves of Populus nigra L. (Salicaceae), which are used as biomonitor to investigate the levels of the trace elements Cd, Pb, Fe, Zn and Cu, were sampled at 30 locations having different pollution levels in the region. The concentrations of elements were determined by atomic absorption spectrometry. The samples were collected at both reference and contaminated locations where iron was found as the priority element. The strong association between a gradient of contamination and concentration in all samples tested indicates that they are reflecting well the environmental changes, and that they appear as appropriate biological indicators of heavy metal contamination

EKOLOJI

Denizli is one of the rapidly developing states in the West Anatolian Region of Turkey Keeping this in view, 30 different plants were selected to study their potential as biomonitors of trace elements like Pb, Cd, Ni, Zn, Fe and Mn (mu g g(-1), dry weight). The samples were collected from two different altitudes of Honaz Dagi, a mauntain overlooking at state of Denizli. The concentrations of trace elements were determined by flame atomic absorption spectrometry (FAAS). The mean concentrations determined at 1000 in altitude ranged between 0.273 to 0.488, 0.099 to 0.488, 0.306 to 0.682, 1.017 to 3.744, and 0.148 to 0.674 (mu g g(-1), dry weight), of Pb, Ni, Zn, Fe and Mn, respectively. At 1600 in altitude, the values ranged between 0.225 to 0.534, 0.150 to 0.842, 0.234 to 0.905, 1.082 to 3.864 and 0.023 to 0.982 (mu g g(-1), dry weight) of Pb, Ni, Zn, Fe, Pb and Mn, respectively. No Cd was detected at both altitudes

(Turkish red pine) in the Western Anatolian part of Turkey

Background: Pinus brutia Ten (Turkish red pine) is a widespread evergreen tree in the Mediterranean and Aegean regions of Turkey. Methods: The barks of red pine were tested as a possible biomonitor of trace element pollution studied in the Western Anatolian part of Turkey. Samples collected from control, industry, roadside, suburban and rural areas from 30 locations in the study area were investigated. The concentration of cadmium, lead, chromium, iron, nickel and copper were determined in the bark of the red pine by atomic absorption spectrometry. Results: As results of this study, the following concentrations were determined: Cd: 0.60 - 0.71 mu g g(-1), Pb: 4.59 - 20.03 [mu g g(-1), Cr: 0.44 - 3.17 mu g g(-1), Fe: 486.35 - 1274.04 mu g g(-1), Ni: 3.56 - 18.87 19 g(-1) and Cu: 3.52 - 15.30 mu g g(-1). Conclusion: The results of this study imply that barks of P brutia can be a useful biomonitor for the determining heavy metal pollution in an area
