| Tartalmi kivonat: | The LM results of the high temperature effect on fresh pollen grains of Platanus hybrida are summarized in this paper. The qualitative and the quantitative alterations are presented herein of the fresh and heated pollen grains at 200 °C during 10', 1 hr., 5, 10, 25 and 50 hours. The Longaxones characteristic features are more gradually expressed by the increasing lengthening of the time of heating. Short time heating resulted in swelling the pollen grains. Characteristic contraction was observed after 50 hours of heating. By the length of time of the heating, the P/E ration increases with several maxima from 1.3-1.6. |
