The phenomenon of partial androsterility of the endemic Dianthus volgicus Juz. (Caryophyllaceae) in the Middle Volga region
With the help of traditional and generally accepted methods of cenopopulational researches one of the aspects of the Volga neoendemic’s sexualization has been studied — the spreading of partial androsterility in different populations of the species and the stability of this process over time and space. It has been discovered that the share of partially androsterile flowers in populations constitutes at an average 10 % of all androgynous and has little influence on the pollinating potential.
