- Intervention effect Pollen from tracking donors had a 32% germination advantage over pollen from tethered donors.
- Intervention effect Tracking flowers had 40% more germinating pollen grains at the end of anthesis.
- Intervention effect Tracking flowers had 44% more pollen tubes midway down the style.
- Intervention effect Solar tracking had no direct effect on pollen tube growth.
- Mechanism More germinating pollen in tracking flowers accounted for increased pollen tube density.
