Transmission electron microscopy of the partially degraded pollen grains from the Thanetian layers of Menat (France) II.
The new partial degradation experiments damaged the ultrastructure of the pollen grains heavily. The 2- aminoethanol and the KMnC^ treatment 24 hours was destructive. In several cases the nearer determination of the pollen grain was impossible. In this way at this fossil material the previously used...

| Tartalmi kivonat: | The new partial degradation experiments damaged the ultrastructure of the pollen grains heavily. The 2- aminoethanol and the KMnC^ treatment 24 hours was destructive. In several cases the nearer determination of the pollen grain was impossible. In this way at this fossil material the previously used solvent, the merkaptoethanol seems to be appropriate for the moderate, partial dissolution to discover ontogenetically or taphonomically important ultrastructural elements. |
