Pollen grain size was used to measure the effect of the presence of a low number of B-chromosomes. The pollen grains of forty-two plants distributed among two classes -those with one to five B-chromosomes and those without B-chromosomes were measured. No significant differences could be detected between the mean pollen grain size of B and non-B-chromosome classes. There is an indication of an effect on the variance in pollen grain size of the B-chromosome class.
