Özet

This study was performed on Centaurea hermannii F. Herm to acquire information about some characteristics (bioclimatic,

edaphic, topographic, biotic etc.) of its habitat and distribution in Istanbul-Turkey. Plant and soil samples were collected

between Subaşı and Akalan Villages, in Çatalca District of Istanbul. Soil texture, structure and other physical and chemical

measurements such as pH, electrical conductivity (EC), saturation, salinity, organic matter, CaCO3 content were determined

by using various analyses.

The result showed that the soils where plants grow on consist of 34% sand, 34% silt and 32% clay. In the plants, the average

contents of some elements (%) were measured as 1.05, 1.05, 2.93 for N, 0.015, 0.02 and 0.034 for P, 0.026, 0.025 and 0.029

for Na, 1.46, 2.58 and 1.90 for K, 1.70, 0.48 and 1.70% for Ca in roots, stems and leaves, respectively. The values above were

compared with the values of other Centaurea species in different regions of Turkey.
