For this experiment, the same four plants are pollinated three different ways: single hand pollinations (each flower pollinated with pollen from one of the donors), mixed donor hand pollinations (each flower pollinated with an equal mixture of pollen from all donors), and field mixed pollinations through natural pollinator visitation by bees and beeflies.
