X-ray effect on the ultrastructure of the pollen grains of Ginkgo biloba L.
Pollen grains of Ginkgo biloba L. were irradiated with CuKa X-ray at 35 KV, 20 mA. Length of time of irradiations were as follows: 5', 15', 35' and 60'. The biopolymer system of the ectexine is relatively resistant to the irradiation, sub-units were not observed. Désintégration i...

| Tartalmi kivonat: | Pollen grains of Ginkgo biloba L. were irradiated with CuKa X-ray at 35 KV, 20 mA. Length of time of irradiations were as follows: 5', 15', 35' and 60'. The biopolymer system of the ectexine is relatively resistant to the irradiation, sub-units were not observed. Désintégration in the ultrastructure was observed in the first place at the intine and the endexine. In the apertural region degradation of the foot layer was also observed. |
