  1. However, only did a few pollen germinate in inter - specific hybridization between cerasus fruticosa and c. avian and many pollen tubes are crosswise on stigma and couldn " t penetrated into style. although a few pollen tubes entered, they couldn " t continue to grow due to accumulation of callosity in pollen tubes. in view of above - mentioned results, the irregular growth of pollen was the main reason to cause the incompatibility of distant hybridization between cerasus fruticosa and c. avium
