Sypnosis Pollen germinated and tubes entered the style within 5 minutes after pollination of common oats, Avena sativa . The tube passed between cells of the conducting tissue near the center of style and into the ovary. The male generative nuclei were near the egg nucleus and polar nuclei within 30 minutes. Within 4 hours the male gamete had entered the egg. The fertilized egg was in prophase 13.5 hours after pollination and a two‐celled proembryo was observed 19 hours after pollination.
