[elektronikus dokumentum] / Kedves Miklós 2000 99-106 Plant cell biology and development 11 The transmission electronmicroscopical, results of three Hungarian lignite samples are presented in this contribution. Two samples of Sequoioxylon gypsaceum and one sample of S. medulläre were the subject of these investigations. Non-experimental and partially dissolved lignite fragments with diethylainine and inerkaptoethanol were investigated with transmission electron microscope method. The new results in comparison to the previously described ones indicate that these samples are in a very poor preservation state. Homogenisation of the secondary wall was observed, but sometimes there are important differences in the electron density of the more or less homogeneous substance.
