Achene Characteristics of Turkish Centaurea (asteraceae) and Their Systematic Application
This article investigates the exomorphic characteristics of the achenes which are achene size, color, and surface pattern, and pappus length, and colour. All these characteristics in seven taxa of Asteraceae namely, C. aggregata Fisch. & C.A. Mey. ex DC. subsp. aggregata, C. sivasica Wagenitz, C. polypodiifolia Boiss. var. polypodiifolia, C. polypodiifolia Boiss. var. szowitziana (Boiss.) Wagen...
متن کاملTaxonomic significance of achene morphology in the genus Centaurea L. (Asteraceae)
Achene morphology of 49 taxa of the genus Centaurea L. was studied in terms of 19 different characteristics. On the basis of the variation in these features, some sections, such as sect. Cyanus with hairy hilum, were separated. Despite various differences, C. leuzeoides and C. gilanica were categorized in the section Psephelloideae, a section with lots of character variations within its species...
متن کاملCytogenetical studies on achene colour polymorphism of Picris asplenoides L. and Urospermum picroides L. (Asteraceae) in Egypt.
Achene morphs of Picris asplenoides L. and Urospermum picroides L. were investigated in order to gain insight into its genetic variation based on the evidence obtained from karyotype analysis, electrophoretic pattern of achene proteins as well as nucleic acid analysis. In Picris asplenoides L., three achene morphs were observed from every inflorescence as follows: violet, brown and white, these...
متن کاملAssessment of the antioxidant potential and fatty acid composition of four Centaurea L. taxa from Turkey.
This paper focused on the assessment of antioxidant property and fatty acid composition of four Centaurea species. The antioxidant activity of its methanol extract was evaluated by several in vitro experiments including phosphomolybedum assay, DPPH assay, β-carotene/linoleic acid, ferric and cupric reducing power. Total phenolic and flavonoid contents were also evaluated. The methanol extract o...
متن کاملComposition of the volatile oils of two Anthemis L. taxa from Turkey.
The essential oils of water-distilled aerial parts of Anthemis pseudocotula and Anthemis cretica subsp. pontica (Asteraceae) were analysed by GC-MS. As a result thirty-five and forty compounds were identified representing 93.1% and 89.0% of the oils, respectively. The main compounds of A. pseudocotula were 1,8-cineole (39.40%), camphor (9.36%), artemisiaketone (5.68%), filifolene (5.15%), and a...
