  • Patent number: 4254580
    Abstract: The production of sunflower seeds (i.e. Helianthus annus seeds) is an important industry in the United States as well as in many other parts of the world. Such seeds are useful in the production of sunflower oil or may serve as a food source for man and other animals. The present invention provides a novel and highly effective technique for enhancing the production of sunflower seeds via an agricultural process wherein a greater proportion of the florets which make up the sunflower are effectively pollinated. The production of sunflower achene which lack the desired kernels accordingly is minimized and a greater seed yield is made possible per growing area.
