| Tartalmi kivonat: | The light-microscopical results of partially dissolved spores and pollen grains of the recent species are summarized in this paper: Dryopteris filix-mas, Juniperus virginiana, Betula verrucosa, Carya illinoensis, Juglans nigra and Platycarya strobilacea. Seven organic solvents - diethylamine, merkaptoethanol, methanol, ethanol, n-propanol, n-butanol and i-amyl alcohol - were used. Length of time: 30, 90, 150, 210, 270 and 330 days, temperature 30°C. Taxonomically important alterations were observed at the pollen grains of Juniperus virginiana, Carya illinoensis and Betula verrucosa. In this respect the spores of Dryopteris filix-mas, and the pollen grains of Juglans nigra and Platycarya strobilacea are very resistant. Concerning the results of the pollen grains of Juniperus virginiana as a new term, the DUHOUX effect is introduced. This is the extreme swelling of the intine, which breaks the exine and peculiar forms appear. This phenomenon may be the result of different influences first observed by DUHOUX as a result of hydratation. |
