Experimental investigations on the pollen grains of Elaeagnus angustifolia L. and Juglans regia L.
Pollen grains of Elaeagnus angustifolia L. and Juglans regia L. were partially degraded with 2-aminoethanol for 30 minutes, 1,5, 10 and 24 hours. Unstained and stained pollen grains were investigated with the LM method. The weak resistance of the sporopollenin of the ectexine of the pollen grains of...

| Tartalmi kivonat: | Pollen grains of Elaeagnus angustifolia L. and Juglans regia L. were partially degraded with 2-aminoethanol for 30 minutes, 1,5, 10 and 24 hours. Unstained and stained pollen grains were investigated with the LM method. The weak resistance of the sporopollenin of the ectexine of the pollen grains of Elaeagnus angustifolia was established during these experiments. Based on the LM data the pollen grains of Juglans regia are relatively resistant. Alterations in the diameter of the pollen grains were established depending on the length of time of the partial degradation. The trend of the alterations was different in the unstained and stained pollen grains. After 24 hours of treatment using the TEM method, moderate disintegrations were observed in the ultrastructure of the ectexine. |
