SINGLE POLLEN TUBE SURVIVES. “In Arabidopsis, typically only a single pollen tube grows towards each ovule. Heterofertilization is likely extremely rare, as only about 1% of ovules attract two or more functional pollen tubes. These numbers indicate that various mechanisms exist in angiosperms to efficiently prevent polyspermy.”
