The ultrastructure of three kinds of apricot pollens by ice nucleation active (INA) bacteria and low temperature was investigated with transmission electron microscopy. The results showed that the ultrastructure of pollen was affected by the INA. The pollen exine was disintegrated by INA. The organelles in pollen were destroyed. The membrane of mitochondrion disappeared. The ridge of mitochondrion was changed into vesiculation.
