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 morphs differ in their color. In the inflorescence of Urospermum picroides L., three achene morphs… Expand
