ECOLOGICAL FEATURES OF CENTAUREA L. SECTION PHALOLEPIS (CASS.) DC. IN TURKEY

In this present study, the ecological characteristics of Phalolepis (Cass.) DC. a section of the Centaurea L. genus growing in Turkish was investigated. Important to note is that all species of the section are restricted endemics. Physico-chemical soil analyses as well as chemical analyses of different parts of the species were conducted. Soil and bedrock samples were investigated resuling in petrographic diagnoses. Discriminant analyses were used to determine the amount of the plant nutritional elements of the different plant parts such as root, stem, and leaf, depending on physical and chemical features of 0-10 cm soil specimens. The amount of the nutrient elements in the roots, stem and leaves, the classification success percentages were 92.3, 92.3 and 88.5, respectively. The discrimination analysis success percentage of the chemical and physical soil contents resulted in 96.2%.
