LM and TEM investigations of partially dissolved and degraded pollen grains of Elaeagnus angustifolia L.
Partially dissolved pollen grains with 8 organic solvents were investigated with light microscope. Dissolution with diethylamine resulted in extremely altered pollen forms. Based on the TEM data of the partial degradation with the 2-aminoethanol and further agents method, it resulted that the sporop...

| Tartalmi kivonat: | Partially dissolved pollen grains with 8 organic solvents were investigated with light microscope. Dissolution with diethylamine resulted in extremely altered pollen forms. Based on the TEM data of the partial degradation with the 2-aminoethanol and further agents method, it resulted that the sporopollenin of Elaeagnus angustifolia is less resistant against degradation. The 2-aminoethanol degraded the ultrastructure of the exine of the pollen grain. A similar extremely soluble sporopollenin was observed previously at the exospore of Equisetum arvense and at the exine of the genus Quercus, Tilia, and Platanus. |
