Summary: • Observation have been conducted on pollen tube growth in approximately 10,000 styles of more than 2000 hand-pollinated flowers. • Our database includes the commercial cultivars Gala, Golden Delicious and Fuji and the pollinizing cultivars Gala and Golden Delicious as well as Manchurian and Snowdrift crabapples and 12 other crabapples (Figs. 1 & 2). • Results have been combined to formulate pollen tube growth patterns suitable for development and testing of a computer-generated pollen tube growth model for Washington State growers.
