Absztrakt (kivonat)
Pollen grains of Malva sylvestris L. were treated with C60 fullerene/benzol solution for 1 - 6 days (Experiment No.: T-12- 294-299) and with merkaptoethanol for 24 hours. The cleaned and dried pollen material was embedded in Araldite and was ultrathin sectioned. The transmission! electron microscopical results are as follows: 1. The protoplasm organells were disintegrated easily. 2. The sporopollenin of the ectexine is relatively resistant. 3. The fullerene accumulated differentially in the ectexine layers and at present object the ultrastructure was suitable for TEM study without any postfixation treatment. 4. In general the thick foot layer accepted less fullerene than the thin tectum and the infratectal layer. 5. The treatment in some cases degraded partially the molecular system of the sporopollenin of the ectexine. 6. Large holes and rarely electron dense globular biopolymer units were observed in linear and irregular arrangement. 7. Occasionally regular pentagon and hexagon units occurred which indicated the presence of a quasi-periodic and/or quasi-equivalent biopolymer organization of the ectexine. 8. The diameter of the negative holes is much larger than those of the quasi-crystalloid dimensions.
