Contrasting effects of ploidy level on seed production in a diploid–tetraploid system
The relationship between polyploidy in diploid and tetraploid Centaurea phrygia and seed production is mediated by a wide range of factors with opposing directions. Wider flower heads displayed higher above the ground suggested higher seed production in diploids while earlier flowering and a lower a...

| Summary: | The relationship between polyploidy in diploid and tetraploid Centaurea phrygia and seed production is mediated by a wide range of factors with opposing directions. Wider flower heads displayed higher above the ground suggested higher seed production in diploids while earlier flowering and a lower abundance of herbivores suggested higher seed production in tetraploids. The importance of different relationships varies between years. Knowledge of the patterns of interactions is thus more important than the specific values of the links and can be used to model the evolution of species traits and plant-herbivore and plant-pollinator interactions in diploid-polyploid systems. |
