| Tartalmi kivonat: | This contribution presents LM results of partially dissolved pollen grains of the following species: Larix decidua MILL., Thalictrum minus L., Platanus hybrida BROT., Tilia platyphyllos SCOP, and Castanea sativa MILL. Diethylamine, merkaptoethanol, methanol, ethanol, n-propanol, n-butanol and i-amyl alcohol were used as solvents at 30 °C, during 30, 90, 150, 210, 270 and 330 days. The Duhoux-effect was observed at the pollen grains of Larix decidua MILL. The sporopollenin of the ectexines of Platanus hybrida and Tilia platyphyllos were the less resistant to the influence of diethylamine. But not so important qualitative alterations were observed at the investigated angiosperm pollen grains. Worth of mentioning is the resistance of the exine of Castanea saliva in contrast to the less resistant exine of the genus Quercus. The variation of the size was statistically investigated at the pollen grains of Platanus hybrida, the peculiar alterations of the pollen grains of Larix decidua, finally the pollen tube development at Tilia platyphyllos. |
