Contrasting effects of ploidy level on seed production in a diploid–tetraploid system

Popis výsledku v původním jazyce

Previous studies demonstrated the effects of polyploidy on various aspects of plant life. It is, however, difficult to determine which plant characteristics are responsible for fitness differences between cytotypes. We assessed the relationship between polyploidy and seed production. To separate the effects of flowering phenology, flower head size and herbivores from other possible causes, we collected data on these characteristics in single flower heads of diploid and tetraploid Centaurea phrygia in an experimental garden. The results showed that the relationship between polyploidy and seed production is mediated by most of the studied factors. Wider flower heads displayed higher above the ground suggested higher seed production in diploids. In contrast, earlier flowering and a lower abundance of herbivores suggested higher seed production in tetraploids. Overall, this study demonstrated that tetraploids possess overall higher fitness estimated as seed production.
