Summary
A factorial cross design was used to evaluate the influence of differences among pollen donors and recipients on variation in stylar attrition of pollen tubes in self-fertile plants of Petunia hybrida. Pollinations to flower buds were used to reduce the inhibitory ability of the style and these crosses were compared with flower pollinations to assess the degree of stylar influence on pollen fertilization ability. There was less pollen tube attrition after bud pollinations than after flower pollinations, indicating that styles of buds were less able to inhibit pollen tubes. The variance component for plants acting as pollen donors tended to be greater after flower pollinations than after bud pollinations. The lower variance in male success after bud pollinations indicates that differences among pollen donors after flower pollinations were due to stylar inhibition of pollen rather than differences in pollen vigor. Since the level of variation in pollen growth after pollination to flowers was greater among clones than among ramets within clones, the differences in pollen fertilization ability are probably genetically based.
