The TEM method was used for pollen grains partially dissolved with diluted glycerine for 30 days. Based on the new experimental data, the sporopollenin of the ectexine of this pollen grains is less resistant and may be degraded very quickly. The inner body, which consists of the intine and protoplasm is more resistant. The sym DO -10.6165/tai.2002.47(1).43
