title: Pollen Tube Growth Rates in Zea mays: Implications for Genetic Improvement of Crops.
abstract: Speed of pollen tube growth is positively correlated with the quality of the resultant sporophytic generation. Therefore, gametophytic competition may be an important adaptive mechanism. Furthermore, pollen tube growth rates may be used to predict the quality of F(1) crosses in crop species.
