Bjorkman, Thomas, 1995: The effect of pollen load and pollen grain competition on fertilization success and progeny performance in Fagopyrum esculentum. Flowers of cultivated buckwheat (Fagopyrum esculentum Moench) often receive natural pollen loads of fewer than 10 pollen grains. The cultivated varieties also have high genetic variability. These observations raise the question of whether seed pro...

Charlesworth, D., 1988: Evidence for pollen competition in plants and its relationship to progeny fitness: a comment. A brief discussion is presented on the existence in natural populations of genetic differences in fertilization ability that can lead to heritable differences in the quality of progeny. Previous workers have suggested that high pollen loads give r...

Palmer, T., M.; Zimmerman, M., 1994: Pollen competition and sporophyte fitness in Brassica campestris: Does intense pollen competition result in individuals with better pollen?. In flowering plants, competition among pollen grains can result in positively correlated responses in sporophytic vigor. Whether this indirect selection on the sporophyte can drive the evolution of sporophytic traits depends in part upon whether t...

Competition among pollen grains to fertilize ovules is expected to lead to increased vigor of the resulting progeny. Tests of this "pollen-competition hypothesis," however, have been equivocal, and this may, in part, result from the leve...

Competition among pollen grains from a single donor is expected to increase the quality of the offspring produced because of the recessive deleterious alleles expressed during pollen-tube growth. However, evidence for such an effect is inconclusiv...

The lack of ability to measure pollen performance traits in mixed pollinations has been a major hurdle in understanding the mechanisms of differential success of compatible pollen donors. In previous work, we demonstrated that nonrandom mating bet...

The prevalence of nonrandom fertilization due to postpollination events has rarely been studied in natural populations, despite important implications for outcrossing rates, mate choice, and plant fitness. Nonrandom paternity within fruits can be...

The relationship of pollen tube growth in vitro and pollen tube growth in situ was studied for several tetra-ploid alfalfa clones.
