Ultrastructure of the partially degraded pollen grains of Corylus avellana L. with 2-aminoethanol and C60 fullerene/benzol solution
Pollen grains of Corylus avellana were partially degraded with 2-aminoethanol for 30 minutes, 1, 5, 10 and 24 hours and the treatment was continued with 5 ml C60 fullerene/benzol solution and 5 ml pure benzol for 5 days. The transmission electronmicroscopical results are as follows: 1. The ectexine...

| Tartalmi kivonat: | Pollen grains of Corylus avellana were partially degraded with 2-aminoethanol for 30 minutes, 1, 5, 10 and 24 hours and the treatment was continued with 5 ml C60 fullerene/benzol solution and 5 ml pure benzol for 5 days. The transmission electronmicroscopical results are as follows: 1. The ectexine and the damaged protoplasm was contrasted by the C60 fullerene without any usual fixation and postfixation processes. 2. The accumulation of the fullerene is not the same on the different parts of the ectexine. 3. Some experiments revealed the molecular system of the ectexine. Mostly cyclic molecules were observed. Clusters of cyclic molecules but sometimes peculiar linear arrangement was observed. 4. Degradation or dissolution of large biomacromolecules were also established. |
