Figure 1 Graphic representation of the treatments used in the
experiment. For the heterospecific treatment, a mix of conspecific
pollen from a different individual and of heterospecific pollen from a
heterospecific individual was applied to the recipient flower. For the
conspecific control, on the same recipient plant a second flower was
treated with conspecific pollen only. Both heterospecific and
conspecific treatments of the same pair would use pollen from the same
conspecific pollen donor individual. Pollen amount used was always
saturating.
