Transmission electron microscopy of partially dissolved exines of different bisaccate gymnosperm pollen grains
In the present paper our TEM observations are published on the bisaccate gymnosperm pollen grains treated previously with different organic solvents. The diethylether is a suitable solvent for studying the biopolymer structure of the inner exine layers: foot layer, endexine and intine. The glycogen...

| Tartalmi kivonat: | In the present paper our TEM observations are published on the bisaccate gymnosperm pollen grains treated previously with different organic solvents. The diethylether is a suitable solvent for studying the biopolymer structure of the inner exine layers: foot layer, endexine and intine. The glycogen molecular structure may be discovered with tetrahydrofuran. N-pentane, and particularly pyrrolidine is the best to dissolve the quasi-crystalloid skeleton of the exine, probably of the plant cell wall. This is a tool to investigate the stabilizing biopolymer system. The detailed study of the stabilizing molecular structures will be the subject of further investigations. |
