| Tartalmi kivonat: | Results of different experiments carried out on pollen grains of Cycas rumphii MlQ. with use of 2- aminoethanol, KMnO-t aq. dil. and merkaptoethanol have been summarized. Alterations in morphology of the studied pollen were observed with the help of light microscope and the superficial degradation was studied with SEM. Ultrastructure of partially degraded exine with 2-aminoethanol and KMnCL was investigated with a view to observe the changes or alterations. Ultrastructural studies reveal that no further thinning or reduction in ectexine was noticed in apertural area of pollen. Molecular structures of different organization levels were observed in highly magnified pictures of the pollen wall. |
